如何在没有 firebase 的情况下在 flutter 中显示推送通知？

在我的 flutter 应用程序中，我必须在没有 firebase 的情况下显示推送通知。我的服务器会在点击特定 API 后向我发送一条消息，并且我希望将该消息显示为推送通知。

你能告诉我一种方法如何在颤振中做到这一点吗？

您可以使用本地通知插件

https://pub.dev/packages/flutter_local_notifications https://pub.dev/packages/flutter_local_notifications

API 响应后，只需在本地通知中显示该数据

FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin = new FlutterLocalNotificationsPlugin(); // initialise the plugin. app_icon needs to be a added as a drawable resource to the Android head project
var initializationSettingsAndroid =
    new AndroidInitializationSettings('app_icon');
var initializationSettingsIOS = IOSInitializationSettings(
    onDidReceiveLocalNotification: onDidReceiveLocalNotification);
var initializationSettings = InitializationSettings(
    initializationSettingsAndroid, initializationSettingsIOS);
flutterLocalNotificationsPlugin.initialize(initializationSettings,
    onSelectNotification: onSelectNotification);
