I am trying to make a camera open using flutter and this is what I get:
E/flutter (26189): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method availableCameras on channel plugins.flutter.io/camera)
E/flutter (26189): #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:157:7)
E/flutter (26189): < asynchronous suspension>
E/flutter (26189): #1 availableCameras (package:camera/camera.dart:56:9)
E/flutter (26189): < asynchronous suspension>
E/flutter (26189): #2 main (package:flutter_realtime_detection/main.dart:11:15)
E/flutter (26189): < asynchronous suspension>
this is the line flutter does not accept:
Future<Null> main() async {
WidgetsFlutterBinding.ensureInitialized();
try {
cameras = await availableCameras();
} on CameraException catch (e) {
print('Error: $e.code\nError Message: $e.message');
}
runApp(new MyApp());
}
I have tried flutter clean, hot reloads but nothing helps(
Here is flutter doctor -v:
