show static method

void show({ required BuildContext context, required List<DraftModeUIDropDownMenuItem> items, })

Presents a dropdown menu anchored below the widget that owns context.

The menu is positioned using the RenderBox of the trigger so it appears directly beneath the caller's bottom-right corner.

Implementation

static void show({
  required BuildContext context,
  required List<DraftModeUIDropDownMenuItem> items,
}) {
  dismiss();

  final renderBox = context.findRenderObject()! as RenderBox;
  final position = renderBox.localToGlobal(Offset.zero);
  final size = renderBox.size;

  // Capture theme from caller context before entering overlay.
  final theme = DraftModeUITheme.maybeOf(context);

  final overlay = Navigator.of(context).overlay!;

  final entry = OverlayEntry(
    builder: (_) => _DraftModeUIDropDownMenuOverlay(
      anchorLeft: position.dx,
      anchorRight: position.dx + size.width,
      anchorTop: position.dy + size.height,
      anchorBottom: position.dy,
      items: items,
      onDismissed: dismiss,
      navigatorContext: context,
      theme: theme,
      animationDuration:
          theme?.animationDurationFast ?? const Duration(milliseconds: 150),
      animationCurve: theme?.animationCurve ?? Curves.easeInOut,
    ),
  );

  _current = entry;
  overlay.insert(entry);
