Example 1 with RouteParameters

use of com.vaadin.flow.router.RouteParameters in project flow by vaadin.

the class AbstractNavigationStateRenderer method handle.

    // If the navigation is postponed, using BeforeLeaveEvent#postpone,
    // pushing history state shouldn't be done. So, it's done here to make
    // sure that when history state is pushed the navigation is not
