Barcode&QRcode Generator and Scanner application IONIC 4, Material design, Admob banner

Introduction

With the increasing demand for efficient and convenient data collection methods, barcode and QRcode scanning has become an essential feature in many industries such as retail, healthcare, and logistics. Ionic Framework, a popular framework for building hybrid mobile applications, provides a powerful solution to integrate barcode and QRcode scanning capabilities into your Ionic 4 application using the Barcode&QRcode Generator and Scanner application.

In this tutorial, we will be building a complete application using Ionic 4, Material Design, and Admob banner that utilizes the Barcode&QRcode Generator and Scanner application. We will cover the installation, implementation, and customization of the application, as well as the integration of Admob banner for monetization purposes.

Step 1: Setting up the Environment

Before we start, make sure you have the following installed:

• Node.js (LTS)
• Ionic CLI (using npm: npm install -g @ionic/cli)
• Android Studio (for Android emulator and building APK)
• Xcode (for iOS simulator and building IPA)

Step 2: Creating the Ionic 4 Project

Create a new Ionic 4 project using the following command:

ionic start barcode-scanner blank

This will create a new Ionic 4 project in a directory called barcode-scanner.

Step 3: Installing Dependencies

Install the following dependencies:

• ionic-ng-barcode: npm install ionic-ng-barcode
• angular material: npm install @angular/material
• admob: npm install ng-admob
• ionic-plugin-fingerprint-aio: npm install ionic-plugin-fingerprint-aio
• cordova-plugin-datepicker: npm install cordova-plugin-datepicker

Update the package.json file to include the required dependencies.

Step 4: Configuring Barcode&QRcode Generator and Scanner

Add the Barcode&QRcode Generator and Scanner plugin to your Ionic 4 project by running the following command:

ionic plugins add ionic-ng-barcode

Modify the app.component.html file to include a button that triggers the scanning process:

<ion-content>
  <ion-button (click)="scan()">Scan QRcode/Barcode</ion-button>
</ion-content>

In the app.component.ts file, add the necessary code to scan for barcodes and QRcodes using the Barcode&QRcode Generator and Scanner plugin:

import { Component } from '@angular/core';
import { BarcodeScanner } from 'ionic-ng-barcode';

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.css']
})
export class AppComponent {
  constructor(private scanner: BarcodeScanner) {}

  scan() {
    this.scanner.scan((result) => {
      console.log(result);
    });
  }
}

Step 5: Implementing Material Design

Add the Material Design components to your Ionic 4 project by running the following command:

npm install @angular/material

Modify the app.component.html file to use Material Design components:

<ion-app>
  <ion-nav [root]="root"]>
    <ion-tab-bar>
      <ion-tab-button [tab]="tab1">
        <ion-icon name="search"></ion-icon>
      </ion-tab-button>
      <ion-tab-button [tab]="tab2">
        <ion-icon name="settings"></ion-icon>
      </ion-tab-button>
    </ion-tab-bar>
    <ion-tab [root]="tab1" tab="tab1">
      <ion-content>
        <ion-button (click)="scan()">Scan QRcode/Barcode</ion-button>
      </ion-content>
    </ion-tab>
    <ion-tab [root]="tab2" tab="tab2">
      <ion-content>
        <ion-item>
          <ion-icon name="information-circle-outline"></ion-icon>
        </ion-item>
      </ion-content>
    </ion-tab>
  </ion-nav>
</ion-app>

Modify the app.component.ts file to include the necessary code for the Material Design components:

import { Component } from '@angular/core';
import { Platform } from 'ionic-angular';
import { SplashScreen } from '@ionic-native/splash-screen';
import { BarcodeScanner } from 'ionic-ng-barcode';

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.css']
})
export class AppComponent {
  root = 'Tab1Page';
  tab1 = 'Tab1Page';
  tab2 = 'Tab2Page';

  constructor(private platform: Platform, private splashScreen: SplashScreen, private scanner: BarcodeScanner) {}

  scan() {
    this.scanner.scan((result) => {
      console.log(result);
    });
  }
}

Step 6: Integrating Admob Banner

Add the Admob plugin to your Ionic 4 project by running the following command:

npm install ng-admob

Modify the app.component.html file to include a banner ad:

<ion-app>
  <ion-header>
    <ion-navbar color="primary">
      <ion-title>Barcode Scanner</ion-title>
    </ion-navbar>
  </ion-header>
  <ion-content>
    <ion-button (click)="scan()">Scan QRcode/Barcode</ion-button>
    <adf-banner [admobEnabled]="true" [interstitial]="false"></adf-banner>
  </ion-content>
</ion-app>

Modify the app.component.ts file to include the necessary code for the Admob plugin:

import { Component } from '@angular/core';
import { Admob } from 'ng-admob';

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.css']
})
export class AppComponent {
  constructor(private admob: Admob) {}

  scan() {
    this.scanner.scan((result) => {
      console.log(result);
    });
  }
}

Step 7: Building and Running the Application

Run the following commands to build and run the application:

• ionic build android (builds the APK)
• ionic run android (runs the application on the Android emulator)
• ionic build ios (builds the IPA)
• ionic run ios (runs the application on the iOS simulator)

Conclusion

In this tutorial, we have demonstrated how to use the Barcode&QRcode Generator and Scanner application with Ionic 4, Material Design, and Admob banner. We have implemented the scanning process, incorporated Material Design components, and integrated Admob banner. This application can be extended to include additional features and functionality to meet specific needs.
