英文:
I'm using firebase messaging in my flutter app but when I run my project it show Stringtoken=FirebaseInstanceId.getInstance().getToken(senderId, "*");
问题
我在我的Flutter应用中使用Firebase消息传递，但当我运行我的项目时，它显示以下代码并在控制台中显示以下错误：
String token = FirebaseInstanceId.getInstance().getToken(senderId, "*");
当我运行我的应用程序时，在控制台中显示以下错误信息：
C:\Users\cerbi\AppData\Local\Pub\Cache\hosted\pub.dartlang.org\firebase_messaging-9.1.4\android\src\main\java\io\flutter\plugins\firebase\messaging\FlutterFirebaseMessagingPlugin.java:166: error: cannot find symbol
String token = FirebaseInstanceId.getInstance().getToken(senderId, "*");
^
symbol: variable FirebaseInstanceId
location: class FlutterFirebaseMessagingPlugin
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
What went wrong:
Execution failed for task ':firebase_messaging:compileDebugJavaWithJavac'.
当我导航到错误消息中指定的特定文件时，其中的代码如下：
private Task<Map<String, Object>> getToken(Map<String, Object> arguments) {
return Tasks.call(
cachedThreadPool,
() -> {
String senderId =
arguments.get("senderId") != null
? (String) arguments.get("senderId")
: Metadata.getDefaultSenderId(FirebaseApp.getInstance());
String token = FirebaseInstanceId.getInstance().getToken(senderId, "*");
return new HashMap<String, Object>() {
{
put("token", token);
}
};
});
}
如何解决这个问题？似乎现有的代码不再起作用。

when I run my application it shows this error in the console:

What went wrong:

and when I navigate to the specific file stated in the error message here is the code in there
private Task<Map<String, Object>> getToken(Map<String, Object> arguments) {
return Tasks.call(
cachedThreadPool,
() -> {
String senderId =
arguments.get("senderId") != null
? (String) arguments.get("senderId")

String token = FirebaseInstanceId.getInstance().getToken(senderId, "*");
return new HashMap<String, Object>() {
{
put("token", token);
}
};
});
}
What can I do to resolve this problem, it seems that the existing code is not working anymore

你应该使用
FirebaseMessaging.getInstance().token
来获取令牌，因为
FirebaseInstanceId.getInstance().getToken
已经被弃用。
英文:
You should use
FirebaseMessaging.getInstance().token
to get token, since
FirebaseInstanceId.getInstance().getToken
is deprecated.

要检索应用程序实例的当前注册令牌，您需要调用FirebaseMessaging.instance.getToken();，如其官方指南此处所述。
英文:
To retrieve the current registration token for an app instance, you need to call
FirebaseMessaging.instance.getToken(); as stated here in their official guide.
