Use case

I'm developing a Flutter debugging package that provides advanced rendering insights and helps identify issues and bottlenecks, but I've encountered a limitation: the PictureRecorder instance used by PaintingContext is private with no public getter to access it.

I propose to add a getter so any 3rd party packages can access this instance.

Proposal

The code change can be simple as:

PictureRecorder get recorder {
    if (_recorder == null) {
      _startRecording();
    }
    assert(_currentLayer != null);
    return _recorder!;
  }
