outputSize method

@override Future<Size?> outputSize()

The size in pixels retrieved by the output.

This should be called after setting AND awaiting CameraController.setControllerPreset. Otherwise, this value could return null. A null value indicates the output is using the default size.

Implementation

@override
Future<Size?> outputSize() async {
  verifyAttached();
  if (specifiedSize == null) return null;
  return Size(
    specifiedSize!.width.toDouble(),
    specifiedSize!.height.toDouble(),
  );
}
