count property Null safety
The number of consecutive taps that this tap represents.
This value will always be greater than zero. When the first pointer in a
possible series completes its tap, this value will be
1, the second
tap in a double-tap will be
2, and so on.
If a tap is determined to not be in the same series as the tap that
preceded it (e.g. because too much time elapsed between the two taps or
the two taps had too much distance between them), then this count will
reset back to
1, and a new series will have begun.
