Hello, I’m Shendi

整了好久，记录一下

引入库

# 系统通知插件flutter_local_notifications: ^9.1.5

在 dart 中导入

import 'package:flutter_local_notifications/flutter_local_notifications.dart';

初始化

首先需要创建通知插件

final FlutterLocalNotificationsPlugin np = FlutterLocalNotificationsPlugin();

然后初始化 Android、IOS的设置

/// 这里的参数为Android通知的图标路径-必须,其中 @mipmap 对应android app->src->main->res->mipmap 文件夹var android = const AndroidInitializationSettings("@mipmap/logo");var ios = const IOSInitializationSettings();np.initialize(InitializationSettings(android: android, iOS: ios));

构建通知描述

var androidDetails = const AndroidNotificationDetails('id 描述','名称描述',importance: Importance.max,priority: Priority.high);var iosDetails = const IOSNotificationDetails();var details = NotificationDetails(android: androidDetails,iOS: iosDetails);

发送/显示通知

// 显示通知// 第一个参数是id,id如果一致则会覆盖之前的通知// 第二个参数是通知标题// 第三个参数通知内容,最后一个参数为上面步骤的描述np.show(DateTime.now().millisecondsSinceEpoch >> 10, title, body, details);

完成代码/封装

/// 通知封装/// author Shendiclass Notification {final FlutterLocalNotificationsPlugin np = FlutterLocalNotificationsPlugin();/// 是否初始化了var isInit = false;/// 初始化void init() {if (isInit) return;isInit = true;var android = const AndroidInitializationSettings("@mipmap/logo");var ios = const IOSInitializationSettings();np.initialize(InitializationSettings(android: android, iOS: ios));}void send(String title, String body) {// 初始化init();// 构建描述var androidDetails = const AndroidNotificationDetails('id描述','名称描述',importance: Importance.max,priority: Priority.high);var iosDetails = const IOSNotificationDetails();var details = NotificationDetails(android: androidDetails,iOS: iosDetails);// 显示通知, 第一个参数是id,id如果一致则会覆盖之前的通知np.show(DateTime.now().millisecondsSinceEpoch >> 10, title, body, details);}}var notification = Notification();

将上面代码拷贝到项目内,使用 notification.send(通知标题,通知内容); 来发送通知
