如何在Flutter中创建服务以使应用始终在后台运行？ [英] How to create a service in Flutter to make an app to run always in background?

问题描述

我想让Flutter应用程序始终在后台运行。使用android，我们必须创建一个始终在后台运行的服务。我没有在Flutter文档中找到有关服务的任何信息。

I would like to make my Flutter application to run always in background. With android, we have to create a Service that runs always in background. I don't find something about Services in the Flutter documentation.

是否可以用Flutter做这种事情？

Is it possible to do this kind of things with Flutter?

推荐答案

目前尚无法直接从颤抖的做到这一点，尽管有时可能会发生变化-请参见此错误/功能请求。不过，您确实有几个选择。

There isn't a way to do this directly from flutter right now although that may change at some point - see this bug/feature request. You do have a couple of options though.

第一个是使用 MethodChannels ，只需编写您想要创建后台服务的android代码（或者，如果您希望始终将其作为后台服务，则可以执行此操作而无需颤抖的通信）。

The first is to use MethodChannels and simply write the android code you want to create a background service (or if you want it to always be a background service you can probably do that without needing communication from the flutter side).

第二个是这两个插件的某种组合- android_alarm_manager 和 android_intent 。但这对所有用例都无济于事。

The second is some combination of these two plugins - android_alarm_manager and android_intent. But that won't help for all use-cases.
