更新的上下文：

当我尝试运行 flutter 项目时，但出现此错误\nError: To set up CocoaPods for ARM macOS, run: arch -x86_64 sudo gem install ffi

我会跑arch -x86_64 sudo gem install ffi，但仍然遇到同样的问题。

这是信息

yomate@Mac-mini yomate % sudo gem install ffi\n/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/universal-darwin21/rbconfig.rb:230: warning: Insecure world writable dir /Users/yomate/FlutterDev/flutter/bin in PATH, mode 040777\nBuilding native extensions. This could take a while...\nSuccessfully installed ffi-1.15.5\nParsing documentation for ffi-1.15.5\nDone installing documentation for ffi after 3 seconds\n1 gem installed\n

如何解决这个问题呢？arch: posix_spawnp: gem: 可执行文件中的 CPU 类型错误，环境：Mini M1

当我想使用这个推荐时 …

如何解决这个问题呢？Error (Xcode): Framework not found Flutter

我尝试了更多方法，

尝试删除 ios 然后 pod install...

试图扑干净...

尝试创建新项目等。

但还是无法解决。

如何解决这个问题呢？

ArgumentError (Invalid argument(s): iOS settings must be set when targeting iOS platform.)

我已经添加了通知，但是当我运行 iOS 模拟器时出现此错误How can solve this issues? ArgumentError (Invalid argument(s): iOS settings must be set when targeting iOS platform.)

但它可以在真实设备上运行，只是不能在iOS模拟器上运行

iOS上使用flutter开发时收不到firebase的通知

我已授予许可并使用邮递员进行测试。

首先，我会得到令牌

Restarted application in 516ms.

Secode：当我去postman测试时，我获得了成功

        }
    ]
}

但我仍然没有收到任何通知。

哪里有问题？

这是代码。

late int _totalNotifications;
  late final FirebaseMessaging _messaging;
  PushNotification? _notificationInfo;

  void requestAndRegisterNotification() async {
    await Firebase.initializeApp();

    _messaging = FirebaseMessaging.instance;
    FirebaseMessaging.onBackgroundMessage(_firebaseMessageingBackgroundHandler);

    NotificationSettings settings = await _messaging.requestPermission(
      alert: true,
      badge: true,
      provisional: false,
      sound: true,
    );

    if (settings.authorizationStatus == AuthorizationStatus.authorized) {
      print('User granted permission');
      String? token …
