ScreenResizeDetector class

A widget that detects changes in screen size and notifies listeners.

This widget listens to screen size changes using LayoutBuilder and triggers onResizeUpdate and onResizeEnd callbacks accordingly.

When the screen size changes, onResizeUpdate is called immediately and onResizeEnd is called after a debounce duration to handle resize events efficiently.

Parameters:

  • child: The child widget to render.
  • onResizeUpdate: A callback function called when the screen size changes.
  • onResizeEnd: A callback function called when the screen resize ends.
