The Gesture Responder System in React Native manages the lifecycle of touch events, allowing views to negotiate responsibility for handling gestures. Here is a detailed breakdown of its lifecycle:
1. Request Phase
onStartShouldSetResponder: This method is called at the start of a touch event. If it returns true, the view will request to become the responder.
onMoveShouldSetResponder: This method is called during a touch move event. If it returns true, the view will request to become the responder.
2. Bubbling Phase
These negotiation methods are called in a bubbling pattern, meaning the deepest component in the hierarchy will be the first to receive the touch event and can claim the responder status.
3. Capture Phase
onStartShouldSetResponderCapture: Similar to onStartShouldSetResponder, but uses event capturing instead of bubbling. This allows a parent view to capture the responder before its children.
onMoveShouldSetResponderCapture: Similar to onMoveShouldSetResponder, but uses event capturing.
4. Grant or Reject Phase
onResponderGrant: Called when the view successfully claims the responder status. This is typically where you provide visual feedback to the user.
onResponderReject: Called if the view's request to become the responder is rejected.
5. Respond Phase
onResponderMove: Called when the user moves their finger while the view is the responder.
onResponderRelease: Called when the touch ends, i.e., the user lifts their finger.
onResponderTerminationRequest: Called when another view wants to claim the responder status. Returning true allows the view to release the responder status.
onResponderTerminate: Called when the responder status is taken away from the view, either by another view or b...
