Correct Gradle Configuration for Play Store Signing
Which Gradle snippet correctly configures signing for a Flutter app to upload to the Play Store with a release build?
Flutter
android {
  signingConfigs {
    release {
      storeFile file('my-release-key.jks')
      storePassword 'storepass'
      keyAlias 'keyalias'
      keyPassword 'keypass'
    }
  }
  buildTypes {
    release {
      signingConfig signingConfigs.release
      minifyEnabled false
      shrinkResources false
    }
  }
}
AThe snippet is missing the signingConfig assignment inside buildTypes.release.
BThe snippet uses incorrect property names like keyStoreFile instead of storeFile.
CThe snippet correctly sets signingConfig for release and references the keystore file and passwords properly.
DThe snippet should set minifyEnabled true for Play Store release builds.

💡 Hint
Check if signingConfig is properly assigned and property names are correct.
