UiSelect<T> class
Generic dropdown select.
Value-based API — pass value + onChanged like a standard controlled
input. The menu is rendered through the ambient Overlay so its
styling stays consistent with the rest of the kit (no Material popup
inside the list).

Properties
- dismissOnTapOutside → bool
-
Whether a pointer tap outside the trigger and menu dismisses it.
Scroll gestures keep the menu open and outside taps pass through to the
underlying control. Defaults to true.

- enabled → bool
-
final
- errorText → String?
-
final
- hashCode → int
-
The hash code for this object.

- key → Key?
-
Controls how one widget replaces another widget in the tree.

- placement → UiSelectPlacement
-
How the overlay positions itself relative to the trigger.
final
- runtimeType → Type
-
A representation of the runtime type of the object.

- shrinkWrap → bool
-
When true the trigger sizes to its content instead of stretching to the
parent's full width — for compact, inline placements (e.g. a top-bar
language switcher).
final
- size → UiSize
-
Defaults to UiSize.lg to match UiInput's default so a Select
trigger and a text field placed side by side in a form render at the
same height without callers having to pass
