Basically, what you want is impossible from the pure Flutter module perspective because it uses autogenerated .android and .ios folders and ignores ones without dot. You can change those autogenerated files, but they will be rewritten with the new generation every time.

You have options:

1. Create a script that automatically adds all the needed stuff to the generated files every time after generation
2. Create an elaborate scheme with a native wrapper module for the flutter module and its means of communication inside with an exposed native(java, kotlin) interface to the main app. Some replacement of the autogenerated code and even flutter tools will still be required. More info here
