2. Counting issue:

When clicking on the + button it shows the following integers sequentially:

-1177495951
1897028546
676585747
-543857052
-1764299851
1310224646
89781847

Note: Running the apk from the releases section seem to work just fine.

I guess maybe the issue from you use a new version of flutter? I see using flutter 2.0, which in my opinion would require FFI 1.0, which we do currently not support, yet!

But, aside from that, getting the increment FAB with the adder crate to not work properly does sound really weird!

I guess I should update the dart-bindgen to FFI 1.0 (sunshine-protocol/dart-bindgen#7) and/or deprecate it and start using the official ffigen provided by the dart team.

I/flutter ( 9503): Scrap Setup Done

Scraping doesn't work and adder shows random numbers. No additional error outputs generated.

Maybe if you can share your setup. I will run using the same.

Also I use android-ndk-r22-windows-x86_64 if that helps
