sir,

I am using Touchkit in vaadin 8 but we convert in vaadin 14 it not supporting why....?How to use vaadin 14 any idea?

There’s no TouchKit for Vaadin 10 or greater, and there’s not going to be. The features have been either obsoleted, integrated into the core framework or dropped in favor of other approaches.
