我无法从 Firebase 向我的应用发送通知，因为每次这样做它都会崩溃
之前它显示了最新版本的 firebase_messaging 插件的错误，因此我将其保留为空，以便 ide 能够获取最新的软件包。
这些是我在 pubspec.yaml 文件中的依赖项
dependencies:
flutter:
sdk: flutter
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^0.1.2
#firebase_auth: ^0.10.0+1
#firebase_core: ^0.4.0
firebase_database: ^3.0.0
firebase_messaging:
dev_dependencies:
我的推送通知代码如下:
firebaseMessaging.getToken().then((token){
print("Token: $token");
});
firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print('on message $message');
final notification=message['notification'];
setState(() {
messages.add(Message(
title: notification['title'],body: notification['body']
));
});
},
onResume: (Map<String, dynamic> message) async {
print('on resume $message');
},
onLaunch: (Map<String, dynamic> message) async {
print('on launch $message');
},
);
这是我运行程序时的 logcat 摘要:

最佳答案
This GitHub issue/comment建议您需要非常密切地关注您正在使用的插件版本。这意味着您还必须保持平台特定依赖项的更新 ( this for Android )。
来自 Firebase 文档:
app/build.gradle:
implementation 'com.google.firebase:firebase-messaging:18.0.0'
