flutter pub add qrcode根據套件公開資料產生的選型評估，僅供參考。
qrcode 包是一個專為 iOS 和 Android 平台設計的 Flutter 插件，用於掃描二維碼。在 iOS 上，它利用 AVCaptureSession 實現高效的條碼檢測；在 Android 上，則使用 ZXing 庫以確保可靠的掃描性能。這一輕量級解決方案使開發者能夠以最少的設定將二維碼掃描功能整合到其應用中。它支援即時掃描，並提供對解碼資料的簡單存取，非常適合需要從二維碼快速取得資料的應用程式。

A flutter plugin for scanning QR codes. Use AVCaptureSession in iOS and zxing in Android.
Add this to your package's pubspec.yaml file:
dependencies:
qrcode: ^1.0.5
You can install packages from the command line:
with Flutter:
$ flutter pub get
Now in your Dart code, you can use:
import 'package:qrcode/qrcode.dart';
class _MyAppState extends State<MyApp> {
QRCaptureController _captureController = QRCaptureController();
bool _isTorchOn = false;
@override
void initState() {
super.initState();
_captureController.onCapture((data) {
print('onCapture----$data');
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Stack(
alignment: Alignment.center,
children: <Widget>[
QRCaptureView(controller: _captureController),
Align(
alignment: Alignment.bottomCenter,
child: _buildToolBar(),
)
],
),
),
);
}
Widget _buildToolBar() {
return Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
FlatButton(
onPressed: () {
_captureController.pause();
},
child: Text('pause'),
),
FlatButton(
onPressed: () {
if (_isTorchOn) {
_captureController.torchMode = CaptureTorchMode.off;
} else {
_captureController.torchMode = CaptureTorchMode.on;
}
_isTorchOn = !_isTorchOn;
},
child: Text('torch'),
),
FlatButton(
onPressed: () {
_captureController.resume();
},
child: Text('resume'),
),
],
);
}
}
To use on iOS, you must add the following to your Info.plist
<key>NSCameraUsageDescription</key>
<string>Camera permission is required for qrcode scanning.</string>
<key>io.flutter.embedded_views_preview</key>
<true/>
