update method

void update()

This is called automatically and sets needsUpdate to true every time a new frame is available.

Implementation

void update() {
  //final video = image.data;
  final hasVideoFrameCallback = video is html.HTMLVideoElement;//'requestVideoFrameCallback' in video.requestVideoFrameCallback(callback);
  if (hasVideoFrameCallback && (video?.readyState ?? 0) >= 4 ) {
    needsUpdate = true;
  }
}
