GoogleService-Info.plist 文件是通过Add Files to "Runner" 选项添加的。所以，它在 Runner 目录中。

• 我已经检查了很多堆栈溢出答案，但无法找出问题所在。

• 我还重新检查了 GoogleService-Info.plist 中的 GOOGLE_APP_ID

• GoogleService-Info.plist 配置没有问题。

• 我还在 [my_project]/ios/Runner/Info.plist 文件中添加了下面的 CFBundleURLTypes 属性。

最佳答案

终于解决了!

简单地说，根据其平台配置 GoogleService-Info.plist 和 GoogleService.json，例如:

// config acc to platform
final FirebaseOptions firebaseOptions = (Platform.isIOS || Platform.isMacOS)
    ? const FirebaseOptions(
        googleAppID: '1:926446789922:ios:e1628wrtecf870f0717b',
        gcmSenderID: '2564624562546',
        apiKey: 'AIzaSyChk3KEG7QYrs4kQfgNxBTbwerwrfCAdgg',
        projectID: 'project-23f',
        storageBucket: 'gs://project-23f.appspot.com',
        databaseURL: 'https://project-23f.firebaseio.com/',
      )
    : const FirebaseOptions(
        googleAppID: '1:926446789922:android:056bd6d9f0717b',
        gcmSenderID: '2564624562546',
        apiKey: 'AIzaSyDBq2tJ82wO0RKzfsguGCp7e6uh3Ko',
        projectID: 'project-23f',
        storageBucket: 'gs://project-23f.appspot.com',
        databaseURL: 'https://project-23f.firebaseio.com/',
      );

final FirebaseApp app =
    await FirebaseApp.configure(name: 'test', options: firebaseOptions);

关于ios - Flutter NSException : Configuration fails. 可能是GoogleService-Info.plist中的GOOGLE_APP_ID无效或自定义选项中设置的，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/62787686/
