  final cameras = await availableCameras();
  runApp(MyApp());
}

Correct

Future<void> main() async {
  final cameras = await availableCameras();
  runApp(MyApp());
}

Target of URI doesn’t exist: ‘package:camera/camera.dart’.

確認 pubspec.yaml 的 dependencies 是否已加入 camera

dependencies:
  flutter:
    sdk: flutter
  camera:
