我正在尝试从 java ret rest api发送通知(使用 firebase admin admin sdk ) Flutter Application ,似乎需要设备令牌发送通知,我找不到如何获取该令牌。我是Flutter和Android的新手,可能会缺少任何关键步骤。如果可以,请你帮助我。谢谢。
使用firebase_messaging: ^10.0.0
,您可以直接使用
String? token = await FirebaseMessaging.instance.getToken();
或
FirebaseMessaging.instance.getToken().then((value) {
String? token = value;
});
将其添加到您的软件包的pubspec.yaml文件:
dependencies:
firebase_messaging: ^6.0.16
您可以从命令行安装软件包:
flutter:
$ flutter packages get
现在在您的飞镖代码中,您可以使用:
import 'package:firebase_messaging/firebase_messaging.dart';
实现:
FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
@override
void initState() {
super.initState();
firebaseCloudMessaging_Listeners();
}
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");
});
}

希望这对您有帮助
,您可以使用firebase消息传递插件发送通知。通过此代码,您可以在控制台中打印令牌。
final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
_firebaseMessaging.configure(
onLaunch: (Map<String, dynamic> message) {
print('onLaunch called');
},
onResume: (Map<String, dynamic> message) {
print('onResume called');
},
onMessage: (Map<String, dynamic> message) {
print('onMessage called');
},
);
_firebaseMessaging.subscribeToTopic('all');
_firebaseMessaging.requestNotificationPermissions(IosNotificationSettings(
sound: true,
badge: true,
alert: true,
));
_firebaseMessaging.onIosSettingsRegistered
.listen((IosNotificationSettings settings) {
print('Hello');
});
_firebaseMessaging.getToken().then((token) {
print(token); // Print the Token in Console
});
}
我们需要在pubspec.yaml文件
中添加此软件包firebase_messaging: ^4.0.0+1
执行软件包获取
现在将其导入您的代码
import 'package:firebase_messaging/firebase_messaging.dart';
创建firebasemessaging的实例
FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
现在,我们只是添加我在下面的链接中的答案中创建的函数

我不清楚您的问题。对于FCM,您必须扩展Firebasemessagingservice。
示例:
class PNPFirebaseMessagingService : FirebaseMessagingService() {
override fun onNewToken(token: String?) {
// you can collect token from here
}
}
