[英]In dialog box how to change container background color when click on it in flutter?
My goal is to achieve the dialog like the below image.我的目标是实现如下图所示的对话框。 I want that when I press the cancel or confirm button in the dialog, the background color of the cancel and confirm buttons should change.我希望当我按下对话框中的取消或确认按钮时,取消和确认按钮的背景颜色应该改变。
I have designed this dialog the same as but only I am not able to change the cancel or confirm container background color when I click on it.我设计了这个对话框,但只有当我单击它时,我无法更改取消或确认容器背景颜色。 my designed dialog is below here.我设计的对话框在下面。
Please help me, anyone, how can I achieve this.请帮助我,任何人,我怎样才能做到这一点。

You need to use StatefulBuilder
to update on dialog.您需要使用StatefulBuilder
更新对话框。
onTap: () {
showDialog(
context: context,
builder: (BuildContext context) {
bool isCancelBtnTappeed = false;
bool isConfirmBtnTappeed = false;
return StatefulBuilder(
builder: (context, setStateSB) {
return Dialog(
shape: RoundedRectangleBorder(
/// ........
GestureDetector(
onTap: () {
setStateSB(() {
isCancelBtnTappeed = true;
});
},
child: Container(
decoration: BoxDecoration(
borderRadius:
BorderRadius.circular(5),
color: isCancelBtnTappeed
? Colors.red
: Colors.white,
