setResolution method

@override Future<bool> setResolution(int width, int height)

Sets the capture resolution in pixels.

The value is a target: each platform negotiates the closest supported size with the device (a portrait request maps to the equivalent landscape sensor size on mobile). The actual size is available through getWidth/getHeight and every captureFrame result. Returns false when no camera is open.

Implementation

@override
Future<bool> setResolution(int width, int height) async {
  final tracks = _stream?.getVideoTracks().toDart;
  if (tracks == null || tracks.isEmpty) return false;
  try {
    // Browsers treat these as ideals and pick the closest supported mode,
    // the same negotiation the native platforms do.
    await tracks.first
        .applyConstraints(dom.MediaTrackConstraints(
            width: width.toJS, height: height.toJS))
        .toDart;
    return true;
  } catch (e) {
    return false;
  }
}
