Flutter firebase 未初始化

Question

收到此错误。 未处理的异常：PlatformException(null-error, Host platform returned null value for non-null return value., null, null)

我已经更新了 .yaml 中的所有 firebase 包，我仍然有这个错误

E/flutter (11230): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(null-error, Host platform returned null value for non-null return value., null, null)
E/flutter (11230): #0      FirebaseCoreHostApi.optionsFromResource (package:firebase_core_platform_interface/src/pigeon/messages.pigeon.dart:242:7)

E/flutter (11230): #3      main (package:mossbets/main.dart:22:3)
E/flutter (11230): <asynchronous suspension>
E/flutter (11230): 

让我还补充一点，我已经调用初始化firebase。一旦我删除了初始化，应用程序就可以正常工作但没有火力

Answer 1

这可能是由于 Firebase CLI 与 firebase 选项的新变化所致。所以要解决这个问题，请添加：

在你的终端

$ flutterfire configure

然后在你的main

// Import the generated file
import 'firebase_options.dart';

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

您可能会被要求验证您的 firebase 帐户，以便您在终端中运行它

dart pub global activate flutterfire_cli

将这两行添加到您的 main.dart 主函数中

void main() async{

 WidgetsFlutterBinding.ensureInitialized();
  // initializing the firebase app
  await Firebase.initializeApp();

   
runApp(MyApp());

}
