selectedItemBuilder property

DropdownButtonBuilder? selectedItemBuilder

A builder to customize the dropdown buttons corresponding to the DropdownMenuItems in items.

When a DropdownMenuItem is selected, the widget that will be displayed from the list corresponds to the DropdownMenuItem of the same index in items.

This sample shows a DropdownButton with a button with Text that corresponds to but is unique from DropdownMenuItem.

To create a local project with this code sample, run:
flutter create --sample=material.DropdownButton.selectedItemBuilder.1 mysample

If this callback is null, the DropdownMenuItem from items that matches value will be displayed.


final DropdownButtonBuilder? selectedItemBuilder;
