flutter_local_notifications

效果

安卓配置(AndroidManifest.xml)

    <uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>
    <uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM" />
    <uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>

可参考下面

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />

    <uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>
    <uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM" />
    <uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>
    <application
        android:label="whisp"
        android:name="${applicationName}"
        android:icon="@mipmap/launcher_icon">

         In particular, this is used by the Flutter engine in io.flutter.plugin.text.ProcessTextPlugin. -->
    <queries>
        <intent>
            <action android:name="android.intent.action.PROCESS_TEXT"/>
            <data android:mimeType="text/plain"/>
        </intent>
    </queries>
</manifest>

ios配置AppDelegate.swift(参考下面)

import flutter_local_notifications

 FlutterLocalNotificationsPlugin.setPluginRegistrantCallback { (registry) in
        GeneratedPluginRegistrant.register(with: registry)
    }

if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate
}

 (参考下面)

import UIKit
import Flutter
import flutter_local_notifications

@main
@objc class AppDelegate: FlutterAppDelegate {

  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    // This is required to make any communication available in the action isolate.
    FlutterLocalNotificationsPlugin.setPluginRegistrantCallback { (registry) in
        GeneratedPluginRegistrant.register(with: registry)
    }

    if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate
    }

    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

  //创建命名构造函数

  // FlutterLocalNotificationsPlugin实例

      await _notificationsPlugin.initialize(

  initPermission() {

  void _configureSelectNotificationSubject() {

      print("点击消息携带的数据$response");
    });

  // 显示通知
  Future<void> showNotification({required String title, required String body, String payload = ""}) async {

      notificationDetails,
      payload: payload,
    );
  }

  /// 取消全部通知
  cancelAll() {
    _notificationsPlugin.cancelAll();
  }

  /// 取消对应ID的通知
  cancelId(int id) {
    _notificationsPlugin.cancel(id);
  }
}

使用

main方法中初始化

NotificationHelper.getInstance().initialize();

首页中进行权限和方法回调绑定和卸载

首页的instate
NotificationHelper.getInstance().initPermission();

首页的dispose

NotificationHelper.getInstance().closeSubject();

调用提示 接收消息直接调用

NotificationHelper.getInstance().showNotification(title: "科学研究", body: "研究开始了", payload: "payload");

这里可以监控点击推送后动作，如跳转页面  response?.data 是携带的数据

 void _configureSelectNotificationSubject() {
    selectNotificationStream.stream.listen((NotificationResponse? response) async {
      // await Navigator.of(context).push(MaterialPageRoute<void>(
      //   builder: (BuildContext context) =>
      //       SecondPage(response?.payload, data: response?.data),
      // ));
      print("点击消息携带的数据$response");
    });
  }
