GesturePatternRecognizer class
Core class to recognize a gesture pattern based on a Morse code-like string.
This class processes gestures and matches them against a predefined
sequence of gestures (pattern). If the gestures match the pattern
within the specified timeout, the onPatternMatched callback is invoked.
Constructors
- GesturePatternRecognizer({required GesturePattern pattern, required Duration timeout, required VoidCallback onPatternMatched})
