When I build my app with >flutter build apk, it creates five files:

  • app-arm64-v8a-release.apk (8.4MB)
  • app-armeabi-v7a-release.apk (8.1MB)
  • app-release.apk (20.1MB)
  • app-x86_64-release.apk (8.6MB)
  • output.json (2KB)

But when I want to upload my app to Firebase App Distribution, it only asks/allows for a single APK file.

Which file should I use and why?

I would suggest to upload an app-release.apk as it is a universal apk which should fit for all architectures.

You have multiple apks in your output directory since flutter generates stripped apks for each architecture.
