问题

主要代码

在运行 Flutter 后,我收到了以下错误:

/C:/Users/username/AppData/Local/Pub/Cache/hosted/pub.dev/firebase_auth_web-5.2.4/lib/firebase_auth_web.dart:92:45: 错误: 无法将参数类型 'Future<void> Function()' 分配给参数类型 'Future<void> Function(App)?'。
 - 'Future' 来自 'dart:async'。
 - 'App' 来自 'package:firebase_core_web/src/interop/app.dart'
 ('/C:/Users/username/AppData/Local/Pub/Cache/hosted/pub.dev/firebase_core_web-2.2.2/lib/src/interop/app.dart')。
    FirebaseCoreWeb.registerService('auth', () async {

尝试过 flutter clean 并下载了 Flutter Core Web。

英文:

code for main

I recieve this error after flutter run

/C:/Users/username/AppData/Local/Pub/Cache/hosted/pub.dev/firebase_auth_web-5.2.4/lib/firebase_auth_web.dart:92:45: Error: The argument
type 'Future<void> Function()' can't be assigned to the parameter type 'Future<void> Function(App)?'.

  • 'Future' is from 'dart:async'.
  • 'App' is from 'package:firebase_core_web/src/interop/app.dart'
    ('/C:/Users/username/AppData/Local/Pub/Cache/hosted/pub.dev/firebase_core_web-2.2.2/lib/src/interop/app.dart').
    FirebaseCoreWeb.registerService('auth', () async {

Tried flutter clean and downloaded flutter core web
