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="android.permission.READ_MEDIA_VIDEO" /><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"/><applicationandroid:label="whisp"android:name="${applicationName}"android:icon="@mipmap/launcher_icon"><activityandroid:name=".MainActivity"android:exported="true"android:launchMode="singleTop"android:taskAffinity=""android:theme="@style/LaunchTheme"android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"android:hardwareAccelerated="true"android:windowSoftInputMode="adjustResize"><!-- Specifies an Android theme to apply to this Activity as soon asthe Android process has started.

</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) inGeneratedPluginRegistrant.register(with: registry)}if #available(iOS 10.0, *) {UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate}GeneratedPluginRegistrant.register(with: self)return super.application(application, didFinishLaunchingWithOptions: launchOptions)}
}
封装类
import 'dart:async';
import 'dart:io';import 'package:flutter_local_notifications/flutter_local_notifications.dart';@pragma('vm:entry-point')
void notificationTapBackground(NotificationResponse notificationResponse) {// ignore: avoid_printprint('notification(${notificationResponse.id}) action tapped: ''${notificationResponse.actionId} with'' payload: ${notificationResponse.payload}');if (notificationResponse.input?.isNotEmpty ?? false) {// ignore: avoid_printprint('notification action tapped with input: ${notificationResponse.input}');}

}
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");});}
