I have a UI like this where there is a drop down button and below that the space which should show only the widget I choose from the DropdownButton.
The Widgets are in different classes like this
List<Widget> contactItems = [
RecentContactsScreen(),
Contacts(),
AgentsList(),
OwnersList(),
];
I need to know how can I implement in a way to achieve this task. Thanks.
DropdownButton 有一个名为 onChange 的属性,您可以在该函数内导航到屏幕
Widget _build(index) {
switch (index) {
case 0:
return Container();
case 1:
return Container();
default:
return Container();
} }
pass the index or create a global variable and change it onChange of drop down. replace the Container with your UI.
