    I am just sharing a small tip on how to reduce your apk file size.

    Go to: android/app/build.gradle

    and then under build types add these lines

    buildTypes {
       release {
           minifyEnabled true
           shrinkResources true
           signingConfig signingConfigs.release
       }
   }

    Run flutter build apk --split-per-abi

    This will build specific apk files for separate cpu architectures for mobile.

    By default the apk that runs in emulator has a lot of debug libraries in it which increases the apk size by a huge factor.

    All the answers are valid
    It seems not an instant solution, but the best approach is to follow the official flutter document for reducing the APK size, LIKE:

    1. remove the unused dart packages from pubspec.yaml
    2. Remove the unused assets like, images, gifs, sounds etc, or Atleast compress them
    3. try to avoid boilerplate code as much as you can
    4. use the central classes for constants instead writing the same code again and again.
