TextSelectionGestureDetectorBuilder class

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.

A TextSelectionGestureDetectorBuilder must be provided a TextSelectionGestureDetectorBuilderDelegate, from which information about the EditableText may be obtained. Typically, the State of the widget that builds the EditableText implements this interface, and then passes itself as the delegate.
