//
// This class is only safe because the TapGestureRecognizer is not
// given a deadline and therefore never allocates any resources.
//
// In any other situation -- setting a deadline, using any of the less trivial
// recognizers, etc -- you would have to manage the gesture recognizer's
// lifetime and call dispose() when the TextSpan was no longer being rendered.
//
// Since TextSpan itself is @immutable, this means that you would have to
// manage the recognizer from outside the TextSpan, e.g. in the State of a
// stateful widget that then hands the recognizer to the TextSpan.
// example:
// _LinkTextSpan(
// style: linkStyle,
// url: 'https://goo.gl/iv1p4G',
// text: 'flutter github repo',
// ), _LinkTextSpan({ TextStyle style, String url, String text }) : super(
style: style,
// text: str ?? url,
text:text,
