如何在dart中使动态字符串的某些单词可点击

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Clickable Words'),
        ),
        body: Center(
          child: ClickableText(),
        ),
      ),
    );
  }
}

class ClickableText extends StatelessWidget {
  final String text = "This is a clickable text.";

  @override
  Widget build(BuildContext context) {
    return RichText(
      text: TextSpan(
        children: _getClickableTextSpans(context),
      ),
    );
  }

  List<TextSpan> _getClickableTextSpans(BuildContext context) {
    List<TextSpan> textSpans = [];

    text.split(" ").forEach((word) {
      textSpans.add(
        TextSpan(
          text: word + " ",
          style: TextStyle(color: Colors.black),
          recognizer: TapGestureRecognizer()
            ..onTap = () {
              _handleWordTap(context, word);
            },
        ),
      );
    });

    return textSpans;
  }

  void _handleWordTap(BuildContext context, String word) {
    showDialog(
      context: context,
      builder: (BuildContext context) {
        return AlertDialog(
          title: Text('Clicked Word'),
          content: Text('You clicked on the word: $word'),
          actions: [
            ElevatedButton(
              onPressed: () {
                Navigator.of(context).pop();
              },
              child: Text('Close'),
            ),
          ],
        );
      },
