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

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 Shendi
class 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(
        '毕业生综合服务平台客服版',
        '毕业生综合服务平台客服版',
        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
