Guides¶

How to build an Ionic Barcode Scanner with Capacitor

Installation¶

npm install @capacitor-mlkit/barcode-scanning@next
npx cap sync

Attention: Please use the next tag to install the latest version of the plugin due to issue #179.

Android¶

Permissions¶

This API requires the following permissions be added to your AndroidManifest.xml before the application tag:

<!-- To get access to the camera. -->
<uses-permission android:name="android.permission.CAMERA" />
<!-- To get access to the flashlight. -->
<uses-permission android:name="android.permission.FLASHLIGHT"/>

You also need to add the following meta data in the application tag in your AndroidManifest.xml:

<meta-data android:name="com.google.mlkit.vision.DEPENDENCIES" android:value="barcode_ui"/>
<!-- To use multiple models: android:value="face,model2,model3" -->

Data Binding¶

Enable the databinding library by setting the dataBinding and enabled build options to true in your module-level (app-level) Gradle file (usually android/app/build.gradle):

android {
    ...
+    buildFeatures {
+        dataBinding true
+    }
+    dataBinding {
+        enabled = true
+    }
}

iOS¶

Minimum Deployment Target¶

Make sure to set the deployment target in your ios/App/Podfile to at least 15.5:

platform :ios, '15.5'

Variables¶

This plugin will use the following project variables (defined in your app’s variables.gradle file):

$androidxCameraCamera2Version version of com.google.mlkit:barcode-scanning (default: 1.1.0)
$androidxCameraCoreVersion version of com.google.mlkit:barcode-scanning (default: 1.1.0)
$androidxCameraLifecycleVersion version of com.google.mlkit:barcode-scanning (default: 1.1.0)
$androidxCameraViewVersion version of com.google.mlkit:barcode-scanning (default: 1.1.0)
$mlkitBarcodeScanningVersion version of com.google.mlkit:barcode-scanning (default: 17.1.0)
$playServicesCodeScannerVersion version of com.google.mlkit:barcode-scanning (default: 16.0.0)

iOS¶

Add the NSCameraUsageDescription key to the ios/App/App/Info.plist file, which tells the user why the app needs to use the camera:

+ <key>NSCameraUsageDescription</key>
+ <string>The app enables the scanning of various barcodes.</string>

Configuration¶

No configuration required for this plugin.

Demo¶

A working example can be found here: robingenz/capacitor-mlkit-plugin-demo

Usage¶

import {
  BarcodeScanner,
  BarcodeFormat,
  LensFacing,
} from '@capacitor-mlkit/barcode-scanning';

const startScan = async () => {
  // The camera is visible behind the WebView, so that you can customize the UI in the WebView.
  // However, this means that you have to hide all elements that should not be visible.
  // You can find an example in our demo repository.
  // In this case we set a class `barcode-scanner-active`, which then contains certain CSS rules for our app.
  document.querySelector('body')?.classList.add('barcode-scanner-active');

  // Add the `barcodeScanned` listener
  const listener = await BarcodeScanner.addListener(
    'barcodeScanned',
    async result => {
      console.log(result.barcode);
    },
  );

  // Start the barcode scanner
  await BarcodeScanner.startScan();
};

const stopScan = async () => {
  // Make all elements in the WebView visible again
  document.querySelector('body')?.classList.remove('barcode-scanner-active');

  // Remove all listeners
  await BarcodeScanner.removeAllListeners();

  // Stop the barcode scanner
  await BarcodeScanner.stopScan();
};

const scanSingleBarcode = async () => {
  return new Promise(async resolve => {
    document.querySelector('body')?.classList.add('barcode-scanner-active');

    const listener = await BarcodeScanner.addListener(
      'barcodeScanned',
      async result => {
        await listener.remove();
        document
          .querySelector('body')
          ?.classList.remove('barcode-scanner-active');
        await BarcodeScanner.stopScan();
        resolve(result.barcode);
      },
    );

    await BarcodeScanner.startScan();
  });
};

const scan = async () => {
  const { barcodes } = await BarcodeScanner.scan({
    formats: [BarcodeFormat.QrCode],
  });
  return barcodes;
};

const isSupported = async () => {
  const { supported } = await BarcodeScanner.isSupported();
  return supported;
};

const enableTorch = async () => {
  await BarcodeScanner.enableTorch();
};

const disableTorch = async () => {
  await BarcodeScanner.disableTorch();
};

const toggleTorch = async () => {
  await BarcodeScanner.toggleTorch();
};

const isTorchEnabled = async () => {
  const { enabled } = await BarcodeScanner.isTorchEnabled();
  return enabled;
};

const isTorchAvailable = async () => {
  const { available } = await BarcodeScanner.isTorchAvailable();
  return available;
};

const setZoomRatio = async () => {
  await BarcodeScanner.setZoomRatio({ zoomRatio: 0.5 });
};

const getZoomRatio = async () => {
  const { zoomRatio } = await BarcodeScanner.getZoomRatio();
  return zoomRatio;
};

const getMinZoomRatio = async () => {
  const { zoomRatio } = await BarcodeScanner.getMinZoomRatio();
  return zoomRatio;
};

const getMaxZoomRatio = async () => {
  const { zoomRatio } = await BarcodeScanner.getMaxZoomRatio();
  return zoomRatio;
};

const openSettings = async () => {
  await BarcodeScanner.openSettings();
};

const isGoogleBarcodeScannerModuleAvailable = async () => {
  const { available } =
    await BarcodeScanner.isGoogleBarcodeScannerModuleAvailable();
  return available;
};

const installGoogleBarcodeScannerModule = async () => {
  await BarcodeScanner.installGoogleBarcodeScannerModule();
};

const checkPermissions = async () => {
  const { camera } = await BarcodeScanner.checkPermissions();
  return camera;
};

const requestPermissions = async () => {
  const { camera } = await BarcodeScanner.requestPermissions();
  return camera;
};

An example of the CSS class barcode-scanner-active with Ionic Framework could be:

// Hide all elements
body.barcode-scanner-active {
  visibility: hidden;
  --background: transparent;
  --ion-background-color: transparent;
}

// Show only the barcode scanner modal
.barcode-scanner-modal {
  visibility: visible;
}

@media (prefers-color-scheme: dark) {
  .barcode-scanner-modal {
    --background: transparent;
    --ion-background-color: transparent;
  }
}

An example of the CSS class barcode-scanner-active without Ionic Framework could be:

// Hide all elements
body.barcode-scanner-active {
  visibility: hidden;
}

// Show only the barcode scanner modal
.barcode-scanner-modal {
  visibility: visible;
}

If you can't see the camera view, make sure all elements in the DOM are not visible or have a transparent background to debug the issue.
