(This is required by ExoPlayer, which is used to play videos).

        targetCompatibility JavaVersion.VERSION_1_8

Generating 64-bit APKs

The Underlying native library tends to blow up the APK size. So, you can build a separate APK for each CPU architecture.

This will also fix an issue with flutter tooling, where 64-bit ARM devices don't work.

Add the following section in android/app/build.gradle -

android {
    defaultConfig {
        ndk {
            abiFilters "<arch>"
        }
    }
}

• For 32-bit APK, replace <arch> with armeabi-v7a, and run $ flutter build apk --release as usual.

• For 64-bit APK, replace <arch> with arm64-v8a, and run $ flutter build apk --release --target-platform=android-arm64.

Now you have 2 Apks, which you will need to publish separately to the Play Store. For that you need to tweak the android:versionCode property to have slightly different values for each build.

The exact "Rules for multiple APKs" can be found here.

Thanks
