You are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
    To generate an app bundle, run:
        flutter build appbundle --target-platform android-arm,android-arm64,android-x64
        Learn more on: https://developer.android.com/guide/app-bundle
    To split the APKs per ABI, run:
        flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi

Answer 1

Follow these steps:

1. you open flutter doctor and type flutter doctor.

2. doctor flutter - Android licenses.

3. you get two options y / N, you type Y, you press enter.

4. after you leave, OK? (y / N) write Y, you press enter.

5. you put Y to everything, accepting everything

6. after accepting you write in the last flutter doctor and wait for the update check in green.

7. after all that you close the flutter doctor and enter your pubspec.yaml, add the latest version of firebase_auth: ^ 0.16.1 and run it.

I hope it will be of great help.
