start method

Future<int?> start({ CameraQuality quality = CameraQuality.hd, int? width, int? height, bool autoRequestPermission = true, })

Starts the camera and returns the native textureId for rendering.

Use the returned ID with a Texture widget for high-performance preview. Returns null if the camera failed to start.

Implementation

Future<int?> start({
  CameraQuality quality = CameraQuality.hd,
  int? width,
  int? height,
  bool autoRequestPermission = true,
}) async {
  if (width != null && width <= 0) {
    throw ArgumentError.value(width, 'width', 'Must be greater than zero.');
  }
  if (height != null && height <= 0) {
    throw ArgumentError.value(height, 'height', 'Must be greater than zero.');
  }
  return _mutex.protect(() async {
    if (autoRequestPermission) {
      final granted = await NexoraSdkPlatform.instance
          .requestCameraPermission();
      if (!granted) return null;
    }
    return NexoraSdkPlatform.instance
        .startCamera(
          width: width ?? quality.width,
          height: height ?? quality.height,
        )
        .then((result) {
          if (result is int) {
            _isRunning = true;
            return result;
          }
          return null;
        });
  });
}
