Permission Handler

On most operating systems, permissions aren't just granted to apps at install time. Rather, developers have to ask the user for permissions while the app is running.

This plugin provides a cross-platform (iOS, Android) API to request permissions and check their status. You can also open the device's app settings so users can grant a permission.
On Android, you can show a rationale for requesting a permission.

flutter pub add permission_handler

bool _hasPermission = false;

Future<void> initPermissions() async {
    final cameraPermission = await Permission.camera.request();
    final micPermission = await Permission.microphone.request();

    final cameraDenied =
        cameraPermission.isDenied || cameraPermission.isPermanentlyDenied;

    final micDenied =
        micPermission.isDenied || micPermission.isPermanentlyDenied;

    if (!cameraDenied && !micDenied) {
      _hasPermission = true;
      await initCamera();
      setState(() {});
    }
  }

 

Finding Available Cameras

bool _isSelfieMode = false;
late FlashMode _flashMode;
late CameraController _cameraController;

Future<void> initCamera() async {
  final cameras = await availableCameras();

  if (cameras.isEmpty) {
    return;
  }

  _cameraController = CameraController(
    cameras[_isSelfieMode ? 1 : 0],
    ResolutionPreset.ultraHigh,
  );

  await _cameraController.initialize();

  _flashMode = _cameraController.value.flashMode;
}

Selfie Mode

---

Future<void> _toggleSelfieMode() async {
  _isSelfieMode = !_isSelfieMode;
  await initCamera();
  setState(() {});
}

IconButton(
  color: Colors.white,
  onPressed: _toggleSelfieMode,
  icon: const Icon(
    Icons.cameraswitch,
  ),
),

Flash Mode

---

late FlashMode _flashMode;

Future<void> _setFlashMode(FlashMode newFlashMode) async {
  await _cameraController.setFlashMode(newFlashMode);
  _flashMode = newFlashMode;
  setState(() {});
}

IconButton(
  color: Colors.white,
  onPressed: _toggleSelfieMode,
  icon: const Icon(
    Icons.cameraswitch,
  ),
),
Gaps.v10,
IconButton(
  color: _flashMode == FlashMode.off
      ? Colors.yellow
      : Colors.white,
onPressed: () => _setFlashMode(FlashMode.off),
icon: const Icon(
    Icons.flash_off_rounded,
  ),
),
Gaps.v10,
IconButton(
  color: _flashMode == FlashMode.always
      ? Colors.yellow
      : Colors.white,
onPressed: () => _setFlashMode(FlashMode.always),
icon: const Icon(
    Icons.flash_on_rounded,

Gaps.v10,
IconButton(

      ? Colors.yellow
      : Colors.white,
onPressed: () => _setFlashMode(FlashMode.auto),
icon: const Icon(
    Icons.flash_auto_rounded,
  ),
),
Gaps.v10,

      ? Colors.yellow
