如何通过TapGestureRecognizer获取有关TextSpan的信息

TapGestureRecognizer _tapGestureRecognizer = TapGestureRecognizer()
  ..onTap = () {
    // 处理点击事件
  };

TextSpan textSpan = TextSpan(
  text: '点击我',
  recognizer: _tapGestureRecognizer,
);

void handleTap() {
  TapGestureRecognizer recognizer = _tapGestureRecognizer;
  TextSpan textSpan = recognizer?.recognizer;
  
  if (textSpan != null) {
    // 获取TextSpan的信息
    String text = textSpan.text;
    TextStyle style = textSpan.style;
    // ...
  }
}
