    Make sure you have firebase_core in your pubspec.yaml
    Then, just use the following in your main:

    await Firebase.initializeApp(
  options: DefaultFirebaseOptions.currentPlatform,
);

    run

    flutter clean

    and

    flutter pub get

    in your terminal.

    If it still fails, please go step by step following the firebase documentation. It should work. https://firebase.google.com/docs/flutter/setup?platform=android

    I just forget to add Google services plugin in android/app/build.gradle:

    apply plugin: 'com.google.gms.google-services'
