在扑中如何清除通知栏? [英] In flutter how to clear notification in bar?

问题描述

我正在学习Google云消息传递，并且 firebase消息传递可以正常工作，但是当用户不这样做时单击通知以打开应用程序，而是通过手动打开并进入前台直接进入应用程序，通知保持不变.我希望与应用相关的那些通知消息在应用进入前台时消失.我该如何实现?

I am learning Google cloud messaging and firebase messaging is working fine, but when a user do not click at the notification to open the app and instead goes directly to app by manually opening it and bringing to foreground, the notification stays. I want those notification message related to my app go away when the app comes to foreground. How can I achieve this ?

推荐答案

它认为在文档.

但是您可以尝试一下.您只需转到Android文件夹中的MainActivity.java，并做这样的事情.

But you can try this. You can just go to your MainActivity.java in your Android folder, and do something like this.

import android.app.NotificationManager;
import android.content.Context;

导入这些软件包.

Import these packages.

 @Override
    protected void onResume() {
        super.onResume();

        // Removing All Notifications
        closeAllNotifications();
    }

    private void closeAllNotifications() {
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.cancelAll();
    }

在MainActivity.java的 onCreate 下添加 onResume 函数.
希望这能解决您的问题.

Add an onResume function below onCreate on MainActivity.java.
Hope this solves your issue.
