TextSelectionGestureDetectorBuilder class Null safety

Builds a TextSelectionGestureDetector to wrap an EditableText.

The class implements sensible defaults for many user interactions with an EditableText (see the documentation of the various gesture handler methods, e.g. onTapDown, onForcePressStart, etc.). Subclasses of TextSelectionGestureDetectorBuilder can change the behavior performed in responds to these gesture events by overriding the corresponding handler methods of this class.

The resulting TextSelectionGestureDetector to wrap an EditableText is obtained by calling buildGestureDetector.
