Feature Request: Support for Flutter: getRenderTree

[OksanaTka]

Hi 👋
In the previous appium-flutter-driver, we had access to Flutter: getRenderTree, which was very useful for debugging widget structure, visibility issues, and for advanced automation assertions.
I noticed that appium-flutter-integration-driver does not support these commands. Would it be possible to bring back Flutter: getRenderTree (or an equivalent), or offer a debug introspection API to inspect the Flutter UI tree?
This would be incredibly helpful when automating dynamic UIs in Flutter.
Thanks for the amazing work!

@OksanaTka yes we can add something!

Also, it would be great to support requestData like in the old driver. We used it to run deep links and simulate data (e.g., breath records).
I’ve opened a separate issue for this as well: #117
Thanks!
