OverBottomSheetController class

Controller that manages the ratio of OverBottomSheet being displayed.

The ratio value ranges from 0.0 (closed) to 1.0 (fully open). Use animateTo, open, and close to animate the sheet position.

Example:

final controller = OverBottomSheetController();

// Listen to value changes
controller.addListener(() => print(controller.value));

// Animate to specific position
controller.animateTo(0.5);

// Open/close shortcuts
controller.open();
controller.close();
