FloatingView class

A widget that provides a floating, draggable, and resizable widget overlay.

The FloatingView is a stateful widget that allows you to overlay a floating widget on top of your existing UI. The floating widget can be dragged around, resized, and toggled between a collapsed and expanded state.

The floating widget's position, size, and behavior are controlled by a FloatingController which must be provided to the FloatingView.

The appearance of the floating widget can be customized using the FloatingViewTheme.

The FloatingView requires a childBuilder function that builds the main content of the widget, and a controller to manage the floating widget's state.

Example usage:

FloatingView(
  childBuilder: () => YourMainWidget(),
  controller: FloatingController(),
  theme: FloatingViewTheme(
    elevation: 8.0,
    backgroundColor: Colors.white,
    radius: 16.0,
  ),
)

See also:

• FloatingController, which manages the state and behavior of the floating widget.
• FloatingViewTheme, which defines the appearance of the floating widget.
