E/flutter (30297): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: MissingPluginException(No implementation found for method scanBarcode on channel flutter_barcode_scanner) E/flutter (30297): #0 MethodChannel._invokeMethod package:flutter/…/services/platform_channel.dart:154 E/flutter (30297): E/flutter (30297): #1 FlutterBarcodeScanner.scanBarcode package:flutter_barcode_scanner/flutter_barcode_scanner.dart:43 E/flutter (30297): E/flutter (30297): #2 _BotonesBusquedaWidgetState.scanQR package:prueba3_git/widgets/botones_busqueda_widget.dart:53 E/flutter (30297): E/flutter (30297):

This happens when in the MainActivity.kt file I change from FlutterActivity to FlutterFragmentActivity. I need it FlutterFragmentActivity to start session with biometric data

To Reproduce Steps to reproduce the behavior:

  1. I have a button that calls the method that scans
  2. qrScanRes = await FlutterBarcodeScanner.scanBarcode( "#ff6666", "Cancelar", true, ScanMode.QR); This is where it throws the aforementioned error

Expected behavior You should be able to open the viewfinder of the camera and be able to scan QR or barcode

Sorry if the report is not right. If you need more information, I will gladly supply it.

I fixed mine with:

128

In file FlutterBarcodeScannerPlugin.java

I've modified all reference to FlutterActivity to FlutterFragmentActivity and now it works.

This is a workaround that works for me.

By exploring the package you can locate it, it remains hidden in the .pub-cache folder /Users/UserFolder/.pub-cache/hosted/pub.dev/flutter_barcode_scanner-2.0.0/android/src/main/java/com/amolg/flutterbarcodescanner/FlutterBarcodeScannerPlugin.java Then, as @wishwelloklu comments, you have to modify the references FlutterActivity to FlutterFragmentActivity and now it works.
