flutter 返回桌面

开发中经常遇到app返回不要退出程序,而是回到桌面即可
flutter端代码:

  _backDeskTop() async {
    //初始化通信管道-设置退出到手机桌面
    String CHANNEL = "android/back/desktop";
    final platform = MethodChannel(CHANNEL);
    //通知安卓返回,到手机桌面
    try {
      final bool out = await platform.invokeMethod('backDesktop');
      if (out) debugPrint('返回到桌面');
    } on PlatformException catch (e) {
      debugPrint("通信失败(设置回退到安卓手机桌面:设置失败)");
      print(e.toString());
    }
    return Future.value(false);
  }

Java代码:

//通讯名称,回到手机桌面
    private final String CHANNEL = "android/back/desktop";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        GeneratedPluginRegistrant.registerWith(this);
        new MethodChannel(getFlutterView(), CHANNEL).setMethodCallHandler(
                (methodCall, result) -> {
                    if (methodCall.method.equals("backDesktop")) {
                        result.success(true);
                        moveTaskToBack(false);
                    }
                }
        );

    }
