OverlayConfiguration<T> class abstract

Describes what overlay to show and how, independent of the specific mechanism (popover, drawer, sheet, dialog, menu, tooltip).

This replaces choosing an OverlayHandler per call site (or relying on a single app-wide adaptive default in ShadcnLayer) with an explicit, per-call configuration object. Each concrete subclass (PopoverConfiguration, DrawerConfiguration, SheetConfiguration, DialogConfiguration, MenuConfiguration, TooltipConfiguration) knows how to present itself via show, and how to adapt itself for the current platform via adaptiveConversion.

Use showOverlay to present a configuration.

Example:

showOverlay(
  context,
  PopoverConfiguration(
    alignment: Alignment.topCenter,
    builder: (context) => const Text('Popover content'),
  ),
);

Methods

adaptiveConversion(BuildContext context) → OverlayConfiguration<T>

Returns an equivalent configuration adapted for the current platform, e.g. a PopoverConfiguration becomes a DrawerConfiguration on mobile.

inherited

show(BuildContext context) → OverlayCompleter<T?>
