flutter - 如何设置枚举变量可观察？

Question

请帮助。我使用颤振和GetX。如何设置枚举变量可观察？enum MyEnumType {open,close}; var _myEnumTypeVar = MyEnumType.open.obs;

Answer 1

我认为您可以使用Rx带有 Type 参数的构造函数：

class EnumX extends GetxController {
  Rx<MyEnum> myEnum = Rx<MyEnum>(MyEnum.open);
}

enum MyEnum {
  open,
  close
}

将枚举用于@chichi 评论/问题的示例：

    EnumX ex = Get.put(EnumX());

    print('enum: ${ex.myEnum.value}');

    ex.myEnum(MyEnum.close);
    //ex.myEnum.value = MyEnum.close; ← same as this

    print('enum: ${ex.myEnum.value}');
