As part of removing all of our analysis_options.yaml for the plugins we need to document all of the public members in video_player_platform_interface. See #45440 for the meta issue on all of these analysis rules.

The missing classes here are:

• DataSource and its members
• VideoEvent and its members
• VideoEventType and all of its values

/cc @cbenhagen do you mind taking this one? It looks like you created the undocumented public members, so I think you'd probably have the best shot at describing these correctly. I took a look but it wasn't obvious to me what the new classes were supposed to be.
