2. Firebase Console의 프로젝트 개요 페이지 중앙에 있는 Android 아이콘을 클릭하여 설정 워크플로를 시작

3. Android 패키지 이름 필드에 앱의 패키지 이름을 입력

- 모듈(앱 수준) Gradle 파일(일반적으로 app/build.gradle)에서 이 패키지 이름(패키지 이름 예시: com.yourcompany.yourproject)

4. 앱 등록

5. GoogleService-Info.plist 다운로드를 클릭하여 Firebase Apple 플랫폼 구성 파일(GoogleService-Info.plist)을 다운로드 

6. Flutter 앱의 android/app 디렉터리로 이동

7. Android 앱에서 Firebase 서비스를 사용할 수 있도록 다음과 같이 google-services 플러그인을 Gradle 파일에 추가

- 루트 수준(프로젝트 수준) Gradle 파일(android/build.gradle)에서 Google 서비스 Gradle 플러그인을 포함하는 규칙을 추가합니다. Google의 Maven 저장소도 있는지 확인

buildscript {

    repositories {
      // Check that you have the following line (if not, add it):
      google()  // Google's Maven repository
    }

    // ...

    dependencies {
      // ...

      // Add the following line:
      classpath 'com.google.gms:google-services:4.3.10'  // Google Services plugin
    }
}

allprojects {
    // ...

    repositories {
      // Check that you have following line (if not, add it):
      google()  // Google's Maven repository
      // ...
    }
}

   - 모듈(앱 수준) Gradle 파일(일반적으로 android/app/build.gradle)에서 Google 서비스 Gradle 플러그인을 적용

// Add the following line:
