BreakifyDebugBanner class

Displays an overlay showing the current responsive breakpoint.

This widget is intended for development and debugging purposes. It overlays the current breakpoint and screen width on top of its child, making it easier to verify responsive layouts while resizing the application.

The banner can be positioned in any corner of the screen and can be enabled or disabled without removing it from the widget tree.

This widget should typically be excluded from production builds.

Requires a BreakifyScope ancestor unless a custom breakpoints configuration is provided.
