The problem is as stated above. If I try to subscribe to a push notification via the url: https://iid.googleapis.com/iid/v1/{token}/rel/topics/{topic}, I always get the following response: {"error":"InvalidToken"}

I have tried using both GET and POST methods but still the same response.

I have checked if the Token is a valid token by using the following url: https://iid.googleapis.com/iid/info/{token} which return the correct data like this:

{
    "application": "com.chrome.windows",
    "subtype": "wp:http://localhost/#2A58747F-DEF7-4C55-8073-126B2D168-V2",
    "authorizedEntity": "856365479457",
    "platform": "WEBPUSH"
}

If my token is valid, then …

在与 Firebase Cloud Messaging 斗争了几个小时后，我发现了问题并想在这里发帖，因为我之前找不到答案。

我的问题是：我正在使用 Firebase Cloud Messaging，但在订阅主题和接收消息时遇到很多麻烦。当尝试直接向设备发送消息时，我经常会收到“未注册”错误，并且在订阅主题时无法订阅主题错误 Domain=com.google.fcm Code=0“(null)”。

我今天已经升级了我所有的 firebase 软件包，我不得不升级到版本 8.0.0-dev.13 以进行 firebase 消息传递，即使由于依赖性问题它仍在开发中。在 Application.Java 中，我有：

package com.halloglobal.flutterapp.hallo;

import io.flutter.app.FlutterApplication;
import io.flutter.plugin.common.PluginRegistry;
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback;
import io.flutter.plugins.GeneratedPluginRegistrant;
import io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService;
import io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin;
import io.flutter.view.FlutterMain;

public class Application extends FlutterApplication implements PluginRegistrantCallback {
@override
public void onCreate() {
super.onCreate();
FlutterFirebaseMessagingService.setPluginRegistrant(this);
}
@override
public void registerWith(PluginRegistry registry) {
FirebaseMessagingPlugin.registerWith(registry.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
}
}

过去运行良好，但现在使用这个新版本，我收到此错误：注意：使用 -Xlint:deprecation 重新编译以获取详细信息。/Users/hallo/Documents/HalloMonoRepo/hallo/android/app/src/main/java/com/halloglobal/flutterapp/hallo/Application.java:7: 错误：包 io.flutter.plugins.firebasemessaging 不存在 import io .flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService; ^ /Users/hallo/Documents/HalloMonoRepo/hallo/android/app/src/main/java/com/halloglobal/flutterapp/hallo/Application.java:8: 错误：包 io.flutter.plugins.firebasemessaging 不存在导入io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin;

我需要如何更改我的 Application.java 才能使用新版本？

我尝试将 Firebase Messaging 安装到旧的 Flutter 项目，但收到此错误消息

因为 firebase_messaging >=7.0.3 <8.0.0-dev.7 取决于 firebase_core ^0.5.0+1 和 firebase_admob >=0.9.1 <0.10.0-dev.1 取决于 firebase_core ^0.4.2+1，firebase_messaging >=7.0.3 <8.0.0-dev.7 与 firebase_admob >=0.9.1 <0.10.0-dev.1 不兼容。所以，因为 AppName 依赖于 firebase_admob ^0.9.3+2 和 firebase_messaging ^7.0.3，版本解析失败。

有谁知道如何解决这个问题？

所以，我在我的flutter应用程序上设置了 FCM 通知。它的工作原理既适用于Android两个在iOSdebug和release模式。

当我创建一个版本apk并在我的手机上测试它时，通知会起作用。但是当我上传appbundle到 Play 商店时，我从 Play 商店下载的版本通知不起作用。该getToken方法返回null，关于为什么会出现这种情况的任何想法？

在我的应用程序中将 Xamarin.Azure.NotificationHubs.Android Nuget 从古老的 0.6 升级到 1.1.4.1（这还涉及从支持库升级到 AndroidX）后 - 没有 Azure 通知中心和 FireBase Nuget（以及使用它们的注释代码），一切正常. 使用这些 Azure/FCM NuGets 启动应用程序时出现异常：

当应用程序关闭或在后台时，我试图停止来自 firebase_message 的默认通知。

我想在应用程序关闭时或使用 local_notifications 插件在后台显示自定义通知，它按预期工作，问题存在于发送消息时，应用程序显示相同的通知两次，默认情况下显示 1 个通知，另一个显示自定义通知。

我无法实现停止默认通知。有人能在这里指出我的错误吗？

初始代码来自 firebase 消息传递示例，删除了不必要的片段并添加了自定义通知。

还附上了当前（不良行为）的图像

如前所述，相同的通知显示两次，想要摆脱图像上显示的第一个通知。

我正在尝试将firebase_messaging包与我的 flutter 应用程序集成。通常它可以正常工作（版本 7.0.3）我正在使用的代码（见下文）但是自从发布了空安全版本我的代码不再工作了。我想知道是否有人可以帮助我找出我做错了什么？

错误导致代码

try {
    fcmToken = await _firebaseMessaging.getToken();
} catch (error) {
    print(error);
}

错误输出
