toImage method

Future<Image> toImage (int width int height)

Creates a raster image representation of the current state of the scene. This is a slow operation that is performed on a background thread.

Implementation

Future<Image> toImage(int width, int height) {
  if (width <= 0 || height <= 0) {
    throw Exception('Invalid image dimensions.');
  }
  return _futurize((_Callback<Image> callback) => _toImage(width, height, callback));
}
