I think your question is not about Flutter, actually.我认为您的问题实际上与 Flutter 无关。 You need to transfer this responsibility to your backend.您需要将此责任转移到后端。 You only need to provide to your database with the Token of the user's device, and the Price and asset he wants to get notification for.您只需要向您的数据库提供用户设备的 Token，以及他想要获得通知的价格和资产。 The backend will handle the asset follow-up and, when the price reaches the user preference, you'll use the provided Token to send him a Push Notification.后台会处理资产跟进，当价格达到用户偏好时，你会使用提供的Token给他发送一个Push Notification。

This way, it will work even though the app is not running in the background这样，即使应用程序未在后台运行，它也能正常工作
