+A QR code scanner that works on both iOS and Android by natively embedding the platform view within Flutter. The integration with Flutter is seamless, much better than jumping into a native Activity or a ViewController to perform the scan.

+## Get Scanned QR Code
+
+When a QR code is recognized, the text identified will be set in 'qrText'.
+
+```dart
+class _QRViewExampleState extends State {
+ final GlobalKey qrKey = GlobalKey(debugLabel: 'QR');
+ var qrText = "";
+ QRViewController controller;
+
+ @override
+ Widget build(BuildContext context) {
+ return Scaffold(
+ body: Column(
+ children: [
+ QRView(
+ key: qrKey,
+ onQRViewCreated: _onQRViewCreated,
+ ),
+ ],
+ ),
+ );
+ }
+
+ void _onQRViewCreated(QRViewController controller) {
+ final channel = controller.channel;
+ controller.init(qrKey);
+ this.controller = controller;
+ channel.setMethodCallHandler((MethodCall call) async {
+ switch (call.method) {
+ case "onRecognizeQR":
+ dynamic arguments = call.arguments;
+ setState(() {
+ qrText = arguments.toString();
+ });
+ }
+ });
+ }
+
+}
+```
+## Flip Camera (Back/Front)
+The default camera is the back camera.
+```dart
+controller.flipCamera();
+```
+
+## Flash (Off/On)
+By default, flash is OFF.
+```dart
+controller.flipFlash();
+```
# TODO'S:
* iOS Native embedding is written to match what is supported in the framework as of the date of publication of this package. It needs to be improved as the framework support improves.
-* Finally, I welcome PR's to make it better :), thanks
\ No newline at end of file
+* In future, options will be provided for default states.
