    • subscribeWindowScreenSize

      public static void subscribeWindowScreenSize(Consumer<ScreenSize> callback, com.vaadin.flow.component.UI ui)
      Subscribes to changes in the browser window's size and calls the specified callback with the updated screen size.

      This method registers a listener for browser window resize events on the provided UI component (if provided) and triggers the callback with the updated window width and height whenever the window is resized. Additionally, it stores the current width and height in ComponentUtil with the keys windowWidth and windowHeight to provide cached values for the callback. The callback receives a ScreenSize that encapsulates the window width and height.

      Parameters:
      callback - The callback function to be invoked with the updated screen size.
      uiOpt - An optional UI component where the resize listener should be attached. If not provided, the listener will not be registered.
