Render Flutter animation directly to video

Question

Considering that Flutter uses its own graphics engine, is there a way to render Flutter animations directly to video, or create screenshots in a frame by frame fashion?

One use case would be that this allows easier demonstration for the audience.

For example, an author wants to create a Flutter animation tutorial, where they builds a demo app and writes a companion blog post, using the animation GIF/videos rendered directly with Flutter.

Another example would be one developer outside the UI team discovers a complex animation has tiny mistake in it. Without actually learning the animation code, they can render the animation into a video and edit that short clip with annotations, then send it to the UI team for diagnoses.
