Flutter “颤振常规”对话框-设置状态不工作
我的常规对话框有问题。我想展示一颗星星。然后，我想改变它的状态时，星是录音，并取代了一个黄色的星图标。 但这是行不通的。对话框未刷新，因此图标未更改。请看下面的源代码，给我指出正确的方向好吗？ 非常感谢Flutter “颤振常规”对话框-设置状态不工作,flutter,dialog,Flutter,Dialog,我的常规对话框有问题。我想展示一颗星星。然后，我想改变它的状态时，星是录音，并取代了一个黄色的星图标。 但这是行不通的。对话框未刷新，因此图标未更改。请看下面的源代码，给我指出正确的方向好吗？ 非常感谢 import 'package:flutter/material.dart'; import 'package:flutter/cupertino.dart'; import 'package:firebase_auth/firebase_auth.dart'; import 'packag

请你帮我完成这一页好吗。谢谢你我建议你使用这个软件包，它很棒
另外，请随意评论，这不能满足您的需要，因此您希望在对话框中单击图标时更改图标的颜色， 但不幸的是，您正在使用无状态小部件
ScaffoldshowGeneralDialogbuilder状态小部件您也可以使用
