Enabling swipe gesture

It can be enabled or disabled using the EnableSwipeGesture property.

Swipe sensitivity

In smaller screens, users may find it difficult to swipe the drawer from the edge, in such cases you can increase the swipe region using the TouchThreshold property. It can be set as below:
