如何让段落中的单词在flutter中可点击？

import 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';

TextSpan _buildTextSpan() {
  String text = "这是一个示例文本";
  List<String> words = text.split(" "); // 将文本按空格分割成单词列表

  List<TextSpan> spans = [];
  for (String word in words) {
    spans.add(
      TextSpan(
        text: word + " ",
        style: TextStyle(color: Colors.black),
        recognizer: TapGestureRecognizer()
          ..onTap = () {
            // 处理点击事件
            print("点击了单词：$word");
          },
      ),
    );
  }

  return TextSpan(children: spans);
}

Widget build(BuildContext context) {
  return Scaffold(
    body: Center(
      child: RichText(
        text: _buildTextSpan(),
      ),
    ),
  );
}
