Use case: use appium or even selenium to test Flutter apps reliably using webdriver w3c protocol

I've been trying to use appium-flutter-driver to interact with dart vm using appium commands based on a webdriver protocol and to be honest this is a nice idea, however, very limited. I'm happy that folks from [selenium](https://github.com/google/webdriver.dart/issues/252) are happy to help and contribute with this project, that would be nice if more people could join as well like appium (@jlipps) and more folks to partner with google and get something more stable, robust and reliable for testing flutter apps outside flutter_driver.

As far as I could see this project allow testing web projects built in flutter via webdriver using firefox, any way to support flutter apps as well???

Thanks in advance for it.
