如何使用GetX弹奏自定义按钮加载？

Question

我想自定义一个按钮，该按钮在使用GETX从API获取数据时显示了加载动作，我可以通过任何控制器。

注意：每个控制器都有字段 isloading

示例：

1. usercontroller
2. dectionsController
3. objecterController，

class BtnAction<T> extends GetView<ConnectivityController> {
  final String text;
  final GestureTapCallback press;
  final Color color;
  final Color textColor;
  final T isLoading;

  const BtnAction(
      {Key? key,
      required this.text,
      required this.press,
      required this.color,
      required this.isLoading,
      required this.textColor})
      : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Obx(() {
      if (controller.connectionStatus.value.name == 'none') {
        return TextButton.icon(
            onPressed: null,
            style: TextButton.styleFrom(backgroundColor: Colors.blueGrey),
            label: Text(text, style: TextStyle(color: textColor)),
            icon: Icon(Icons.wifi_off_sharp, color: textColor));
      } else {
        if (isLoading as (T).isLoading) {
          return TextButton(
            onPressed: press,
            style: TextButton.styleFrom(
              splashFactory: NoSplash.splashFactory,
              backgroundColor: color,
              primary: textColor,
              padding: EdgeInsets.zero,
            ),
            child: Text(text),
          );
        } else {
          return TextButton(
            onPressed: press,
            style: TextButton.styleFrom(
              splashFactory: NoSplash.splashFactory,
              backgroundColor: color,
              primary: textColor,
              padding: EdgeInsets.zero,
            ),
            child: Text(text),
          );
        }
      }
    });
  }
}

//on click
SizedBox(
            width: double.infinity,
            child: Padding(
              padding: const EdgeInsets.symmetric(vertical: 12, horizontal: 15),
              child: BtnAction<UserController>(
                text: "Filter",
                textColor: Colors.white,
                color: Colors.black,
                isLoading: controller,
                press: () async {
                  controller.fetchUser(UserRequest());
             
                },
              ),
            ),
          ),

请给我一些建议，以了解我该如何实现这一目标。

谢谢你！！
