         }).navigate();
 

Parameters:

handler - a handler to set

Returns:

this instance for chaining

public Optional<Consumer<SupportsAfterViewNavigationHandler.AfterViewNavigationEvent<V>>> getAfterNavigationHandler()

Specified by:

getAfterNavigationHandler in interface SupportsAfterViewNavigationHandler<V extends View<?>>
