GestureRecognizerState enum Null safety
The possible states of a PrimaryPointerGestureRecognizer.
The recognizer advances from ready to possible when it starts tracking a primary pointer. When the primary pointer is resolved in the gesture arena (either accepted or rejected), the recognizers advances to defunct. Once the recognizer has stopped tracking any remaining pointers, the recognizer returns to ready.
- defunct → const GestureRecognizerState
Further pointer events cannot cause this recognizer to recognize the gesture until the recognizer returns to the ready state (typically when all the pointers the recognizer is tracking are removed from the screen).
- possible → const GestureRecognizerState
The sequence of pointer events seen thus far is consistent with the gesture the recognizer is attempting to recognize but the gesture has not been accepted definitively.
- ready → const GestureRecognizerState
The recognizer is ready to start recognizing a gesture.
→ const List<
A constant List of the values in this enum, in order of their declaration.
