Camer Preview, always use front camera

Hi
I use a Camera Preview in my app, and my app must always use the front camera for preview. It works fine on iPhone and iPad.

But now I have try on a Samsund Tab A8 android tablet, install my app (APK)
But on android, it always use back camera.

I have try to use "CameraLensDirection" But can't get anything to work

anyone have an idea how i can get it to always select the front camera

Here is my code:

import 'dart:convert';
import 'package:camera/camera.dart';

class CameraPhoto extends StatefulWidget {
  const CameraPhoto({
    Key? key,
    this.width,
    this.height,
  }) : super(key: key);

  final double? width;
  final double? height;

  @override
  _CameraPhotoState createState() => _CameraPhotoState();
}

class _CameraPhotoState extends State<CameraPhoto> {
  CameraController? controller;
  late Future<List<CameraDescription>> _cameras;

  @override
  void initState() {
    super.initState();
    _cameras = availableCameras();
  }

  @override
  void didUpdateWidget(covariant CameraPhoto oldWidget) {
    super.didUpdateWidget(oldWidget);
    if (FFAppState().makePhoto) {
      controller!.takePicture().then((file) async {
        Uint8List fileAsBytes = await file.readAsBytes();
        final base64 = base64Encode(fileAsBytes);

        FFAppState().update(() {
          FFAppState().fileBase64 = base64;
        });
        FFAppState().update(() {
          FFAppState().makePhoto = false;
        });
      }).catchError((error) {});
    }
  }

  @override
  void dispose() {
    controller?.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return FutureBuilder<List<CameraDescription>>(
      future: _cameras,
      builder: (context, snapshot) {
        if (snapshot.connectionState == ConnectionState.done) {
          if (snapshot.hasData && snapshot.data!.isNotEmpty) {
            if (controller == null) {
              controller =
                  CameraController(snapshot.data![0], ResolutionPreset.max);
              controller!.initialize().then((_) {
                if (!mounted) {
                  return;
                }
                setState(() {});
              });
            }
            return controller!.value.isInitialized
                ? MaterialApp(
                    home: CameraPreview(controller!),
                  )
                : Container();
          } else {
            return Center(child: Text('No cameras available.'));
          }
        } else {
          return Center(child: CircularProgressIndicator());
        }
      },
    );
  }
}
