attach method

  1. @override
Future<void> attach(
  1. covariant CameraController controller
)

Called when an output should be attached to a CameraController.

This should not need to be called by a user directly unless implementing their own CameraOutput.

Implementation

@override
Future<void> attach(covariant CameraController controller) async {
  super.attach(controller);
  _controller = controller;
  _previewWidgetCompleter = Completer<Texture>();
  _previewWidgetCompleter.complete(
    Texture(textureId: await controller.camera.attachPreviewTexture()),
  );
}
