Flutter allows do host native views using "Platform Views"

android: https://docs.flutter.dev/platform-integration/android/platform-views

ios: https://docs.flutter.dev/platform-integration/ios/platform-views

From what i can tell from reading docs and searching online: In theory you could call your kmp module using this feature, but you would have to modify your flutter code, and android/ios specific code too, and setup other things like compose multiplatform to work correctly, but i'm not an expert in flutter nor have used this feature so i cannot say if it is difficult and give examples.
