MinFloatingController class

Controls the open/closed state of any floating component (Popover, Tooltip, Dropdown, Sheet, Select, Dialog…).

Can be owned by the component itself or externally by the caller.

Usage:

final controller = MiniFloatingController();
controller.show();
controller.hide();
controller.toggle();

// Listen to changes:
controller.addListener(() { ... });

// Read state:
if (controller.isOpen) { ... }
