在 pubspec.yaml 文件中添加 firebase_auth 或 cloud_firestore 时，构建失败并出现异常（firebase_core 正在运行）：

Question

From the run terminal of android studio:

FAILURE: Build failed with an exception.

• Where: Script 'C:\\Flutter\\src\\flutter\\packages\\flutter_tools\\gradle\\flutter.gradle' line: 362

• What went wrong: A problem occurred configuring project ':cloud_firestore_web'.

Could not find method implementation() for arguments [project ':firebase_core'] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Similar issue with firebase_auth.

Had a similar problem recently, here are the steps that fixed it for me.

1. Run flutter pub upgrade to upgrade all the Firebase plugins to the latest versions.

2. Use the steps at https://firebase.flutter.dev/docs/migration to check for any deprecated code.

3. In the android/build.gradle file, make sure the google services dependency is classpath 'com.google.gms:google-services:4.3.3' or whatever the latest version is.

4. In the android/app/build.gradle file, if you have any dependencies of the form implementation 'com.google.firebase:[firebase-product:version-number] then get rid of those lines

5. Run flutter clean
