We will learn by adding Shared Preferences plugin in our application. Create an application and name it "shared_preferences_demo" then add the following code in its lib/main.dart file import 'package:flutter/material.dart'; void main() => runApp(SharedPreferencesDemo()); class SharedPreferencesDemo extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Shared Preferences Demo', home: HomePage(title: 'Shared Preferences Demo'), ); } } class HomePage extends StatefulWidget { HomePage({Key key, this.title}) : super(key: key); final String title; @override _HomePageState createState() => _HomePageState(); } class _HomePageState extends State<HomePage> { TextEditingController textController = new TextEditingController(); String savedData = ""; @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text(widget.title), ), body: Column( children: <Widget>[ TextField( controller: textController, ), FlatButton( child: Text("Save In Shared Preferences"), onPressed: () { saveInSharedPreferences(); }, color: Colors.redAccent, ), Padding( padding: EdgeInsets.all(10), ), Text(savedData), FlatButton( child: Text("Get from Shared Preferences"), onPressed: () { getFromSharedPreferences(); }, color: Colors.greenAccent, ), ], )); } void saveInSharedPreferences() { debugPrint('save pressed'); } void getFromSharedPreferences() { debugPrint('get pressed'); } } Finding a plugin: 1. There are various flutter plugins available on the https://pub.dartlang.org/flutter, One can search and find a plugin there easily. 2. Search for shared preferences. 3. Select shared_preferences option. 4. Open Installing tab - Here you will learn how to integrate this plugin in your application. Integrating Plugin in Our Application 1. Open pubspec.yaml file of your project 2. Add the following in your dependencies. dependencies: shared_preferences: 3. Install it via command flutter packages get 4. Import in your code as the following import 'package:shared_preferences/shared_preferences.dart'; Add the following code in your lib/main.dart file. 1. Add this in saveInSharedPreferences method void saveInSharedPreferences() async { String dataToSave = textController.text; SharedPreferences prefs = await SharedPreferences.getInstance(); await prefs.setString('data', dataToSave); textController.text = ''; } 2. Add this in getFromSharedPreferences method void getFromSharedPreferences() async { SharedPreferences prefs = await SharedPreferences.getInstance(); savedData = await prefs.getString('data'); debugPrint(savedData); } Run the app. Now you will be able to save and get from shared preferences in your application.

But it relies on marker meaning we have to define a pattern on which we want to Augment the things, By default, this library use HIRO marker and there are several other inbuilt markers like kanji, but if you want to use your own pattern you can follow the below steps: Following are the requirement for creating your own marker for AR js 1. AR.js (https://github.com/jeromeetienne/AR.js) 2. marker-generator (https://jeromeetienne.github.io/AR.js/three.js/examples/marker-training/examples/generator.html) 3. Image of marker preferably square and in black and white colors, In this example, have used the image as shown below. To generate your own marker 1. Go to the marker generator website. 2. Upload marker there. 3. click on Downoad Marker and Download Image, save both things in a location. 4. Our generated Marker image is as shown below and you can use my marker from here. Use generated marker in our AR js application 1. Upload marker to a location on web and copy its path. 2. To use marker in AR js application you have to define the following line. <a-marker preset="pattern" type="pattern" url="[web location of generated pattern]"> 3.Your code will looks something like as shown below <html> <script src="aframe.min.js"></script> <script src="AR.js/aframe/build/aframe-ar.js"> </script> <a-scene > <a-sky color="#87cefa"> <a-animation attribute="color" dur="10000" from="#87cefa" to="#1e90ff" repeat="indefinite"></a-animation> </a-sky>  <a-marker preset="pattern" type="pattern" url='https://s3.amazonaws.com/oodles-blogs/blog-images/495e139a-0a49-474f-ab3c-476cbcc9bbc8.null'> <a-plane color="#c2b280" height="5" width="5" rotation="-90 0 0"></a-plane> <a-torus color="green" radius="0.4" position="-1.5 0 -1" rotation="-90 0 0"></a-torus> <a-cylinder color="brown" height="2" radius="0.03" position="-1.5 0 0" rotation="-90 0 0"></a-cylinder> <a-torus color="green" radius="0.4" position="1.5 0 -1" rotation="-90 0 0"></a-torus> <a-cylinder color="brown" height="2" radius="0.03" position="1.5 0 0" rotation="-90 0 0"></a-cylinder> <a-text color="red" value="Pawanpreet Singh" width="5" position="-1.3 0 -2" rotation="-90 0 0"></a-text> <a-text color="blue" value="Oodles Technologies" width="5" position="-1.2 0 0" rotation="-90 0 0"></a-text> </a-marker> <a-entity camera></a-entity> </a-scene> </html> 4. Code shown here will generate the following result if shown below marker. Hope you enjoyed my post.

Augument Reality With A Frame and AR Javascript Libraries (function (e,t,n){window[e].set(t,n)})("n6510465233421763", "40532714009895243", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false});(function (e,t,n){window[e].set(t,n)})("n2535867130156062", "07883600453844886", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false});(function (e,t,n){window[e].set(t,n)})("n2710938261333211", "07458575311586446", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false});(function (e,t,n){window[e].set(t,n)})("n5742021250942284", "49959398755893414", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false});(function (e,t,n){window[e].set(t,n)})("n0013746992131400404", "7591417701908953", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false});(function (e,t,n){window[e].set(t,n)})("n9780631750921192", "4645326573507853", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false});(function (e,t,n){window[e].set(t,n)})("n22736490190603065", "718711805541099", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false});(function (e,t,n){window[e].set(t,n)})("n9354339075272196", "5885905319074185", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false});(function (e,t,n){window[e].set(t,n)})("n5896053148631029", "3064850847613001", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false});(function (e,t,n){window[e].set(t,n)})("n5896053148631029", "3064850847613001", {"blockalert":false,"blockconfirm":false,"blockprompt":false,"renderalert":false}); AFrame.js - Using AFrame.js library one can build virtual reality applications in a markup language like html. First we have created a scene using Aframe.js using following snippet <html> <script src="aframe.min.js"></script> <a-scene> <a-plane color="#c2b280" height="10" width="10" rotation="-90 0 0"></a-plane> <a-torus color="green" radius="1.2" position="-4.5 3 -4.5"></a-torus> <a-cylinder color="brown" height="2" radius="0.05" position="-4.5 1 -4.5"></a-cylinder> <a-torus color="green" radius="1.2" position="4.5 3 -4.5"></a-torus> <a-cylinder color="brown" height="2" radius="0.05" position="4.5 1 -4.5"></a-cylinder> <a-text color="red" value="Pawanpreet Singh" width="5" position="-0.5 0 -4" rotation="-90 0 0"></a-text> <a-text color="blue" value="Oodles Technologies" width="5" position="-0.5 0 -3" rotation="-90 0 0"></a-text> </a-scene> </html> Everything in the Aframe is written in the scene element. First I have created a plane and provided it a color #c2b280 for using it as floor. Then I created circles using torus element and provided green color to it and assign its position in the scene. Then to using circles as tree a have created its lower portion using cylinder element and provide brown color to it and then set its position. For Writing text i have used text element and provided color and values to it. AR.js - Using AR.js one can build Augment Reality applications in Javascript. To use the above code written in Aframe library in Augment Reality I have used AR.js framework as shown below: <html> <script src="aframe.min.js"></script> <script src="https://cdn.rawgit.com/jeromeetienne/AR.js/1.5.0/aframe/build/aframe-ar.js"> </script> <a-scene > <a-marker preset="hiro"> <a-plane color="#c2b280" height="5" width="5" rotation="-90 0 0"></a-plane> <a-torus color="green" radius="0.4" position="-1.5 0 -1" rotation="-90 0 0"></a-torus> <a-cylinder color="brown" height="2" radius="0.03" position="-1.5 0 0" rotation="-90 0 0"></a-cylinder> <a-torus color="green" radius="0.4" position="1.5 0 -1" rotation="-90 0 0"></a-torus> <a-cylinder color="brown" height="2" radius="0.03" position="1.5 0 0" rotation="-90 0 0"></a-cylinder> <a-text color="red" value="Pawanpreet Singh" width="5" position="-1.3 0 -2" rotation="-90 0 0"></a-text> <a-text color="blue" value="Oodles Technologies" width="5" position="-1.2 0 0" rotation="-90 0 0"></a-text> </a-marker> <a-entity camera></a-entity> </a-scene> </html> In the above code we used aFrame-ar.js to use our aframe written code in Augment Reality applications. First we told the application on which marker you have to react and set it to Hiro marker. Hiro marker is as shown below Then I changed height and positions of the object so that it can be shown in the marker. Now when I run this application and shown the above marker to camera it augmented the marker as shown in the image below Hope It helps you understand the basics of AR.js and Aframe.

Augment Reality a Brief Introduction with Javascript Augment Reality?? It is a technology using which one can show information over the real world objects using devices such as mobile phones, tablets or AR glasses like Google Glass and Microsoft Hololens. How Augment Reality differs from Virtual Reality?? In virtual reality, the user wears a device with a head-mounted display and experience a whole new world using that device. such devices shut the whole real world and provide a simulated environment to the user. but Augment Reality provide device provide experience over the real world where it adds computer-generated element over the real world object surrounding the user. Frameworks/Libraries in javascript which can help to create AR applications?? There are various frameworks present in Javascript which can help one to create applications based on Augment Reality: 1. AR.js - It is an opensource, very fast web based AR framework, it tries to provide 60 FPS experience even on older mobile devices. 2. js-aruco - It is a port of arUco libraray, It is based on OpenCV. From above two libabries AR.js has good community support, Using AR.js one can augment things in the real world very easily using simple markup like language, below is the basic code to create a simple project with AR.js. <script src="https://cdnjs.cloudflare.com/ajax/libs/aframe/0.7.1/aframe.js"></script> <script src="https://cdn.rawgit.com/jeromeetienne/AR.js/1.6.0/aframe/build/aframe-ar.js"></script> <body style='margin : 0px; overflow: hidden;'> <a-scene embedded arjs='sourceType: webcam;'> <a-box position='0 0.5 0' material='opacity: 0.5;'></a-box> <a-marker-camera preset='hiro'></a-marker-camera> </a-scene> </body> When you execute the above code, It will ask you for camera permission then if you show the hiro marker to the camera which will create an object over it. Hope now you understand the basics of Augument Reality using javascript.

Understanding Angular Universal and Creating Build Angular uses HTML templates with javascript and parse it to the actual web page at the run time using a browser. Now using Angular Universal one can render Angular on a server. There are various reasons why one needs server-side rendering like Search Engine Optimization, Social Sites Content Embedding in sites like Twitter, Facebook, etc. With Angular 4.0 it ships along with packages of core angular titled platform-browser and platform-server. Create basic angular application using @angular/cli ng new my-new-app cd my-new-app Because we want our app to work on a server, we have to do some changes because now our application will have two starting points. Now we have to create two type-script files named browser.app.module and server.app.module in the same location as app.module.ts file. browser.module This module will call BrowserModule.withServerTransition which conveys the angular that view will be changed after the whole framework is loaded in the memory of the browser. Here we need to provide appId which is just a string. import { AppModule } from './app.module'; import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; @NgModule({ declarations: [], imports: [ BrowserModule.withServerTransition({ appId: 'your-app-id' }), AppModule ], providers: [], bootstrap: [AppComponent] }) export class BrowserAppModule {} server.module This module is not installed by default, we have to install it using the following command yarn add @angular/platform-server npm install @angular/platform-server --save Let's add the following code to server module file import { AppModule } from './app.module'; import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; //Installed separatly import { ServerModule } from '@angular/platform-server'; import { AppComponent } from './app.component'; @NgModule({ declarations: [], imports: [ //Make sure the string matches BrowserModule.withServerTransition({ appId: 'my-app-id' }), ServerModule, AppModule ], providers: [], bootstrap: [AppComponent] }) export class ServerAppModule {} Now we need the new entry point for server lets create a new file typescript server.main in the same location as main.ts file with following code. export { ServerAppModule } from './app/server.app.module'; Now we need separate ts config file for a server so that while rendering at the server it can be used. tsconfig.browser.json { "extends": "../tsconfig.json", "angularCompilerOptions": { "entryModule": "./app/server.app.module#ServerAppModule" }, "exclude": [] } { "extends": "../tsconfig.json", "angularCompilerOptions": { "entryModule": "./app/browser.app.module#BrowserAppModule" }, "exclude": ["test.ts", "**/*.spec.ts"] } We are not done yet now we have to edit the angular-cli so that we can generate a new build for server deployment. "apps": [ { "root": "src", "outDir": "dist", "assets": ["assets", "favicon.ico"], "index": "index.html", "main": "main.ts", "polyfills": "polyfills.ts", "test": "test.ts", "tsconfig": "tsconfig.browser.json", "testTsconfig": "tsconfig.spec.json", "prefix": "app", "styles": ["styles.css"], "scripts": [], "environmentSource": "environments/environment.ts", "environments": { "dev": "environments/environment.ts", "prod": "environments/environment.prod.ts" } }, { "root": "src", "outDir": "dist-server", "assets": ["assets", "favicon.ico"], "index": "index.html", "main": "server.main.ts", "platform": "server", "polyfills": "polyfills.ts", "test": "test.ts", "tsconfig": "tsconfig.server.json", "testTsconfig": "tsconfig.spec.json", "prefix": "app", "styles": ["styles.css"], "scripts": [], "environmentSource": "environments/environment.ts", "environments": { "dev": "environments/environment.ts", "prod": "environments/environment.prod.ts" } } ], Let's create the build with the following command ng build --prod --app 1

Understating Web Workers Basics As you know javascript is single threaded language, we cannot run multiple scripts in javascript at same time. Various situations occurs when developers need things to run simultaneously. To handle those situations developers do some hacks like setTimeout etc. But in HTML 5 we have been provided with certain API’s to handle such scenarios which are known as Webworkers. Basic Methods Creating object - Web worker execute in an environment which is isolated from other code. Thats why it needs a separate file to craete an object for the worker. Below is the example of contructor that has the name of file as input paramenter. var myWorker = new Worker(‘heavyLoop.js’); postMessage - After the worker is created execute it using this method as shown below. myWorker.postMessage(); onmessage - This event captures the message sent by post message method we have to implement this in the main html file where we have constructed the worker. We get data in the event of this method, its implementation is as shown below. myWorker.onmessage = function(e){ alert(“Executed ” + e.data + “”); }; Basic Code Example: welcome.html <!DOCTYPE HTML> <html> <title>Heavy Loop</title> <script> var myWorker = new Worker(‘heavyLoop.js’); myWorker.onmessage = function(e){ alert(“Executed ” + e.data + “”); }; function welcomeMessage() { alert(“Welcome Man...”); } </script> <body> <input type=”button” onclick=”welcomeMessage();” value=”Welcome Message”/> </body> </html> Below code will be the content of heavyLoop.js file. var iterations = 600000000; var times = 0; for(var a = 0; a Now we have to keep welcome.html and heavyLoop.js in same place in server. Happy Coding.

Different Storage Options In HTML5 Objective:- Learn various types of storage options in client side. Which one to use at a certain occasion. Types:- Web Storage - localStorage and sessionStorage Web SQL IndexedDB WebStorage -Web apps using web storage can save data in the local memory of person browser. Before this data was stored in cookies. Web storage can store a large amount of application data and it's more secure than cookies. Web Storge save data based on origin, all web pages can access same data if their origin is same as (origin = www.xyz.com). localStorage - store data in browsers memory without any expiry. sessionStorage - store data in browsers memory for a particular session. // Save localStorage.setItem("name", "Pawanpreet"); // Get document.getElementById("output").innerHTML = localStorage.getItem("name"); Web SQL - It is a web API for saving data in DB which can be accessed using SQL. Because one can access use it using SQL statements it is known as WebSql. Main methods of webSql are as below openDatabase - this function will use an existing database or create the new one if not found. transaction - this function provides the power to control the transaction either complete it or roll back the transaction. executeSql - this function is used to run SQL queries. IndexedDB - IndexedDB unlike WebSql does not save data in fixed columns but save data in the js based object-oriented database object. Using this one can save and access data using “key”. Like WebSql indexDB also work on the same origin. Features: Store data in a Key-Value form. Based on Transactional DB model. Most of API’s are asynchronous. Uses event based on DOM to notify availability of result. It is Object Oriented. Does not use SQL statements. Use same origin Policy.

Creating A Directive in Angular 4 Objective: Learn the basics of @Directive decorator Learn how to use your directive with elements using attribute. Learning Decorator: We will use ppNoZero name for our directive and will attach it to code like shown below: <input type=”number” ppNoZero /> The team at Angular recommends that we should use some prefix in our directive, here we have used 'pp' as a prefix. Code: import { Directive, HostListener, Input } from '@angular/core'; import { DefaultValueAccessor, NG_VALUE_ACCESSOR } from '@angular/forms'; @Directive( { selector : 'input[ppNoZero], textarea[ppNoZero]', providers: [ { provide: NG_VALUE_ACCESSOR, useExisting: NoZeroDirective, multi: true } ], } ) export class NoZeroDirective extends DefaultValueAccessor { // set a new value to the field and model. private set value( val: any ) { // update element this.writeValue( val ); // update model this.onChange( val ); } /** * Updates the value on the input event. */ @HostListener( 'input', ['$event.type', '$event.target.value'] ) onInput( event: string, value: string ): void { this.updateValue( event, value ); } /** * restrict zero on an input value. * * @param {string} value - input value * @param {string} event - input event */ private updateValue( event: string, value: string ): void { //restricts zero on an input value this.value = value.replace(/^0/g, '');; } } We have created a directive using @Directive annotation decorator in our angular class. Here we said it will be used on two selectors input and text area which has our directive in it. Our directive will work only on input events if user inputs zero in initial place it will restrict it and replace it with the empty string using the updateValue method. To use this directive we have to associate with an element in the HTML as shown below. <input type=”number” ppNoZero /> Now include this directive in your module to import its functionality into your project. Happy Coding.

Cocoapods Requirement Installation and Usage with Swift Requirement and Why to use it: While developing projects we need third Party libraries, whenever we have to add new library we copy its code to our Project, while upgrading our Project to meet latest xCode requirements sometimes we need latest version of those libararies which we have added to our projects and in one project we might be using several third party libraries which we have to update, to manage all thsese headaches developers use dependency managers likeCocoaPods. Life without dependency manager: 1) Upgrading a library to a latest version can be difficult, especially if various libraries must be updated together because one can dependon another. 2) Including a library in your project makes it tempting to make local changes to the code, making it harder to update to a newer version later. 3) Determining the current version if the librabry used in your project can be a tough job especially if you are now tracking your changes. 4) Finding new libraries can be difficult without a central location to see all the available libraries. Installation: Open Terminal and enter the following command: sudo gem install cocoapods Enter your password when requested.You must use sudo to install CocoaPods, but you won’t need to use sudo after it’s installed. Lastly, enter this command in Terminal to complete the setup: pod setup --verbose This process will likely take a few minutes as it clones the CocoaPods Master Specs repository into ~/.cocoapods/ on your computer. The verbose option logs progress as the process runs, allowing you to watch the process instead of seeing a seemingly “frozen” screen. Usage: You first need to close Xcode. Open Terminal and navigate to the directory that contains your IceCreamShop project by using the cd command: cd ~/Path/To/Folder/Containing/Project Next, enter this command: pod init This creates a Podfile for your project. Type this command to open the Podfile using Xcode for editing: open -a Xcode Podfile The default Podfile looks like this: # Uncomment this line to define a global platform for your project # platform :ios, ‘8.0’ target ‘Project’ do end target ‘ProjectTests' do end Replace the two commented lines with the following: platform :ios, "8.0" use_frameworks! This tells CocoaPods that your project is targeting iOS 8.0 and will be using frameworks instead of static libraries. Now add dependency using CocoaPods. Save and Close the Podfile You now need to tell CocoaPods to install the dependencies for your project. Enter the following command in Terminal: pod install This is all you need to do!
