selectedItemBuilder property

ZeroDropdownButtonBuilder? selectedItemBuilder
final

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

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

{@tool dartpad} This sample shows a ZeroDropdownButton with a button with Text that corresponds to but is unique from ZeroDropdownMenuItem.

** See code in examples/api/lib/material/dropdown/dropdown_button.selected_item_builder.0.dart ** {@end-tool}

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

Implementation

final ZeroDropdownButtonBuilder? selectedItemBuilder;
