我已经构建了一个带有 Flutter 的应用程序，它就像一个提醒一样工作。
即使应用程序关闭，如何向用户显示通知？
最佳答案
对于提醒，我会推荐 Flutter Local Notifications Plugin .它有一个强大的调度API。来自本地通知的文档:
Scheduling when notifications should appear - Periodically show a notification (interval-based) - Schedule a notification to be shown daily at a specified time - Schedule a notification to be shown weekly on a specified day and time - Ability to handle when a user has tapped on a notification when the app is the foreground, background or terminated
对于推送通知，您可以使用 Firebase Cloud Messaging 或 one signal插件或者您可以通过 platform-channels 本地实现
编辑:即使应用程序终止，您也可以根据特定条件触发通知。这可以通过在后台运行 dart 代码来实现。引用官方常见问题:
Can I run Dart code in the background of an Flutter app? Yes, you can run Dart code in a background process on both iOS and Android. For more information, see the Medium article Executing Dart in the Background with Flutter Plugins and Geofencing.
关于push-notification - Flutter:即使应用关闭也会推送通知，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53572110/
