State the lifecycle of Gesture Responder System?

A touch event has three phases: start, move and release.

1. Request A view can request to become the touch responder in the: – start phase by returning true from onStartShouldSetResponder – move phase by returning true from onMoveShouldSetResponder
2. Bubbling Similar to the web, these negotiation functions are called in a bubbling pattern. Therefore, the deepest component will become the responder.
3. Override However, a parent can choose to override and claim responsibility. This is done by returning true from either onStartShouldSetResponderCapture or onMoveShouldSetResponderCapture.
4. Granted or Rejected If a view’s request is granted or rejected onResponderGrant or onResponderReject is invoked appropriately.
5. Respond Finally the view can then respond using one of the following handlers:

• onResponderMove
• onResponderRelease
• onResponderTerminationRequest
• onResponderTerminate

After a view has successfully claimed touch responder status, its relevant event handlers may be called.
