如何在 Dart 中将 RxInt 转换为 Int ||扑？

Question

我正在玩 flutter，

我遇到了一个错误，没有得到任何合适的解决方案

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

======== Exception caught by widgets library =======================================================
The following _TypeError was thrown building Obx(dirty, state: _ObxState#76641):
type 'int' is not a subtype of type 'RxInt' of 'function result'

The relevant error-causing widget was: 
  Obx file:///D:/flutter/mini_rupiya/lib/views/screens/payment.dart:84:17
When the exception was thrown, this was the stack: 
#0      DepositController.total (package:mini_rupiya/controllers/deposit_controller.dart)

======== Exception caught by rendering library =====================================================
The following assertion was thrown during layout:
A RenderFlex overflowed by 99736 pixels on the bottom.

The relevant error-causing widget was: 
  Column file:///D:/flutter/mini_rupiya/lib/views/screens/payment.dart:38:20
The overflowing RenderFlex has an orientation of Axis.vertical.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex.

Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.

The specific RenderFlex in question is: RenderFlex#d0b84 relayoutBoundary=up3 OVERFLOWING
...  needs compositing
...  parentData: offset=Offset(26.0, 26.0) (can use size)
...  constraints: BoxConstraints(0.0<=w<=359.4, 0.0<=h<=507.7)
...  size: Size(359.4, 507.7)
...  direction: vertical
...  mainAxisAlignment: center
...  mainAxisSize: max
...  crossAxisAlignment: center
...  verticalDirection: down

====================================================================================================

这是出现此错误的行

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

我正在为 NumberFormat 使用 intl 包在我将其转换为在控制器上使用 .obs() 之前它工作正常

如果有人能描述一下，那将是一个很大的帮助

Answer 1

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

表示函数返回一个整数。不是 RxInt。

为 Rx 类型赋值时使用值属性。示例：

myInteger.value = 100;

从 Rx Type 获取值时，

myInteger.value

Answer 2

您可以使用 .toInt() 将 RxInt 转换为 int。它也适用于其他 Rx 东西！
