即使关闭该应用程序，Flutter应用程序仍然可以运行代码吗？我正在尝试构建一个通知用户的应用程序，即使该应用程序已关闭。希望得到答案。 tia。

默认情况下，您必须以特定于平台的方式集成背景服务。

但是我发现此软件包主要为您处理本机集成： flutter_background_service 。

final service = FlutterBackgroundService();
  await service.configure(
    androidConfiguration: AndroidConfiguration(
      // this will executed when app is in foreground or background in separated isolate
      onStart: onStart,

      // auto start service
      autoStart: true,
      isForegroundMode: true,
    ),
    iosConfiguration: IosConfiguration(
      // auto start service
      autoStart: true,

      // this will executed when app is in foreground in separated isolate
      onForeground: onStart,

      // you have to enable background fetch capability on xcode project
      onBackground: onIosBackground,
    ),
  );
  service.startService();

代码段从包装示例在这里。

如何将软件包添加到您的项目：

打开 pubspec.yaml 文件
添加 flutter_background_service： ^2.4.3 to dependenty e节
运行 flutter Pub Get

By default you would have to integrate your background service on a platform specific way.

But I found this package that handles the native integration mostly for you: flutter_background_service.

final service = FlutterBackgroundService();
  await service.configure(
    androidConfiguration: AndroidConfiguration(
      // this will executed when app is in foreground or background in separated isolate
      onStart: onStart,

      // auto start service
      autoStart: true,
      isForegroundMode: true,
    ),
    iosConfiguration: IosConfiguration(
      // auto start service
      autoStart: true,

      // this will executed when app is in foreground in separated isolate
      onForeground: onStart,

      // you have to enable background fetch capability on xcode project
      onBackground: onIosBackground,
    ),
  );
  service.startService();
