GestureDetector

GestureDetector is a non-visual widget primarily used for detecting the user’s gesture . To identify a gesture targeted on a widget, the widget can be placed inside GestureDetector widget.

GestureDetector class Null safety. A widget that detects gestures . Attempts to recognize gestures that correspond to its non-null callbacks. If this widget has a child, it defers to that child for its sizing behavior.

android.view.GestureDetector. Detects various gestures and events using the supplied MotionEvent s . The OnGestureListener callback will notify users when a particular motion event has occurred. This class should only be used with MotionEvent s reported via touch (don’t use for trackball events).

The main difference between InkWell and GestureDetector lies in Material widget . InkWell must have a Material Widget as an ancestor. However, there is no such compulsion for GestureDetector widget. Otherwise, in many ways, these two widgets share common features.
