qrscan_plus

A Flutter plugin for scanning QR/barcodes and generating QR code images.

Platform Support

Feature	Android	iOS
scan() (camera)	✅	✅
scanPhoto() (gallery image)	✅	✅
generateBarCode()	✅	✅
scanPath(path)	✅	❌
scanBytes(uint8list)	✅	❌

• On iOS, scanPath and scanBytes are not implemented.
• generateBarCode generates a QR image (PNG bytes on iOS, image bytes on Android).

Installation

dependencies:
  qrscan_plus: ^1.0.6

Android Setup

1) Add JitPack repository

This plugin depends on android-zxingLibrary from JitPack. Add JitPack in your Android repositories.

If you use settings.gradle(.kts) with dependencyResolutionManagement:

dependencyResolutionManagement {
    repositories {
        google()
        mavenCentral()
        maven("https://jitpack.io")
    }
}

If your project still uses legacy allprojects repositories:

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}

2) Permissions

Add required permissions in your app manifest (android/app/src/main/AndroidManifest.xml):

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Notes:

• Gallery picking with scanPhoto() may work without manually requesting storage permission on modern Android.
• If your app explicitly requests media/storage permissions at runtime, use Android-version-aware logic (Android 13+ media permissions differ from legacy storage permissions).

iOS Setup

Minimum iOS deployment target: 12.0.

Add usage descriptions in your app Info.plist:

<key>NSCameraUsageDescription</key>
<string>This app needs camera access to scan QR/barcodes.</string>

<key>NSPhotoLibraryUsageDescription</key>
<string>This app needs photo library access to scan QR/barcodes from images.</string>

Usage

import 'package:qrscan_plus/qrscan_plus.dart' as scanner;

Future<void> runQrscan() async {
  final cameraResult = await scanner.scan();
  final photoResult = await scanner.scanPhoto();
  final qrBytes = await scanner.generateBarCode('https://github.com/itxmubi/qrscan_plus');
}

Android-only methods:

final byPath = await scanner.scanPath('/storage/emulated/0/Download/test.png');
final byBytes = await scanner.scanBytes(uint8list);

Error Handling Recommendation

Handle platform exceptions around scan/generate calls:

try {
  final result = await scanner.scanPhoto();
  // use result
} on PlatformException catch (e) {
  // handle e.code / e.message
}
