flutter build apkすると`Execution failed for task ':app:processReleaseResources'.`と出る

原因

flutter build apk -t -t lib/main_staging.dart --releaseでapkファイルを作成しようとしていた

解消法

flutter build appbundle -t lib/main_production.dart --releaseでaabファイルを作成する

手元でflutter build apkした際に出たエラー

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
