解释问题：
我现在试着让firebase_messaging工作了将近一个星期。 我成功地设置了一个旧的Xcode APNS应用程序，该应用程序在生成所有新证书等后都可以工作。 但是有了firebase_messaging我根本没有收到任何通知。 我甚至重新创建了一个新的颤振，firebase和appstoreconnect项目/应用程序。 但是我根本没有收到来自Firebase的通知，无论是在本机Xcode中实现还是在Flutter中实现。 如果我订阅了一个尚不存在的主题，它正在创建中;Android和Analytics上的通知以及iOS和Android上的InAppMessaging 工作正常，所以肯定有一些东西在工作。
到目前为止我尝试过：
在- 原生 Xcode 和 Flutter/Dart 上firebase_messaging的官方示例项目
- 重新创建所有许可证/项目
- 按主题发送消息(无论如何我都计划这样做)
- 从GitHub/stackoverflow应用补丁/修复/提示。
用于重新创建配置的代码片段：
重新创建的步骤可能只是下载 Firebase 消息传递示例项目，或者按照为原生 Xcode 或 Flutter 设置 Firebase 消息传递的官方文档进行操作。重新创建此处列出的示例的基本步骤：
实现的插件(所有最新版本)：
- firebase_messaging
- firebase_core
- firebase_analytics
Flutter/Dart (main.dart)：
void firebaseCloudMessaging_Listeners() {
if (Platform.isIOS) iOS_Permission();
firebaseMessaging.getToken().then((token){
print(token);
});
firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print('on message $message');
},
onResume: (Map<String, dynamic> message) async {
print('on resume $message');
},
onLaunch: (Map<String, dynamic> message) async {
print('on launch $message');
},
);
}
void iOS_Permission() {
firebaseMessaging.requestNotificationPermissions(
IosNotificationSettings(sound: true, badge: true, alert: true)
);
firebaseMessaging.onIosSettingsRegistered
.listen((IosNotificationSettings settings)
{
print("Settings registered: $settings");
});
}
void subscribeToFB() {
firebaseMessaging.subscribeToTopic('-------------Sandbox');
print("--- SUBSCRIBED ---");
}
void unsubscribeFromFB() {
firebaseMessaging.unsubscribeFromTopic('-------------Sandbox');
print("--- UNSUBSCRIBED ---");
}
已实现的 Pod(所有最新版本)：
- pod 'Firebase/Messaging'
- pod 'Firebase/Analytics'

IDE(Xcode/VS Code @ macOS HS)不返回任何错误;调试日志中也没有错误。该应用程序报告工作正常，但消息无法通过。
有人可以帮我吗？谢谢！
解决方法是删除建议的 .p8 密钥文件(从 Firebase 控制台>项目设置>云消息传递)，而是放入 APNS 开发和发布证书。
