I was able to find the other file_picker versions but I have no idea how to replace them within flet or the flutter sdk either. |

Question
I need some help with a build error that I cannot resolve. My app uses the FilePicker control and I get a an error when building the apk:
I get the same error if I comment out the FilePicker controls and everything related to them.
Flutter Doctor:
I've tried different versions of the Android SDK (35) as well as flutter (3.24.0 - 3.24.5)
Any help is appreciated 😊
