如何在 Dart 中将 RxInt 转换为 Int || 扑？

Question

我正在玩扑扑，

我遇到错误并且没有得到任何正确的解决方案

在我的应用程序中，我的GetX控制器中有一些可观察的变量，当尝试应用某种格式然后在此处获取日志时

这是出现此错误的行

\n

Obx(() => Text("You will get : ${NumberFormat.currency(locale: \'HI\', name: "INR", symbol: "\\u{20B9}").format(_depositController.total.value.round()/100)}"))\n

\n

我正在使用intl包，在NumberFormat我将其转为.obs()在控制器上使用之前它工作正常

如果有人可以描述这一点，这将是一个很大的帮助

Answer 1

type 'int' is not a subtype of type 'RxInt' of 'function result'

表示该函数返回一个整数。不是 RxInt。

当给 Rx 类型赋值时，使用 value 属性。例子：

myInteger.value = 100;

从 Rx Type 获取值时，

myInteger.value
