英文:
The argument type 'Dialog' can't be assigned to the parameter type 'Widget Function(BuildContext)'
问题
以下是翻译好的部分：
我试图在Dialog中显示一个Form小部件，如下所示：
onPressed: () async {
switch (currentScreen.toString()) {
case 'OverviewScreen':
() => showDialog(
context: context,
builder: const Dialog(child: FormBasicDetails()));
break;
}
},
但是在builder行出现以下错误：
参数类型'
Dialog'无法分配给参数类型'Widget Function(BuildContext)'。
英文:
I am trying to display a Form Widget 2ithin a Dialog as following:
onPressed: () async {
switch (currentScreen.toString()) {
case 'OverviewScreen':
() => showDialog(
context: context,
builder: const Dialog(child: FormBasicDetails()));
break;
}
},
But I get the following error at the builder line:
> The argument type 'Dialog' can't be assigned to the parameter type
> 'Widget Function(BuildContext)'

showDialog(
context: context,
builder: (context) => const Dialog(
英文:
builder provides callback method with context.
It will be
showDialog(
context: context,
builder: (context) => const Dialog(
