Issue: TextEditingController Textspan's recognizer raising error on initializing text
Labels: a: text input,framework,has reproducible steps,P2,found in release: 2.8,found in release: 2.10,team-framework,triaged-framework

https://user-images.githubusercontent.com/58595897/151553482-d8c685c1-2681-4872-a743-e00932d1e829.mov


Here I extend TextEditingController to highlight(also clickable) the keyword "ali". It is working perfectly whenever the user types "ali". But when initializing text to the controller, it is showing a lot of errors. Someone pls help me with how I can resolve this error.

Note: When I initialize the text and remove "recognizer" from "textspan" it is working perfectly without showing any error. I guess this issue is happening because of "recognizer" in the textspan.

here is my code, pls uncomment line number 15 to see the error.

```dart
import 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';
import 'package:kyubook/utils/utility.dart';

class TexspanTap extends StatefulWidget {
  @override
  _TexspanTapState createState() => _TexspanTapState();
}

class _TexspanTapState extends State<TexspanTap> {
  final MyTextEditingcontroller _editingcontroller = MyTextEditingcontroller();

  @override
  void initState() {
    //_editingcontroller.text = "dghali";
    super.initState();
  }

  @override
  void dispose() {
    _editingcontroller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: SafeArea(
        child: Column(
          children: [
            TextField(
              controller: _editingcontroller,
            ),
          ],
        ),
      ),
    );
  }
}

class MyTextEditingcontroller extends TextEditingController {
  @override
  TextSpan buildTextSpan(
      {required BuildContext context,
      TextStyle? style,
      required bool withComposing}) {
    if (text.toLowerCase().contains("ali")) {
      final List<InlineSpan> spans = [];

      final int indexOfAli = text.indexOf("ali");

      spans.add(TextSpan(text: text.substring(0, indexOfAli)));

      spans.add(
        TextSpan(
            text: text.substring(indexOfAli, indexOfAli + 3),
            style: const TextStyle(color: Colors.red),
            recognizer: TapGestureRecognizer()
              ..onTapDown = (final details) {
                commonToast("Touched");
              }),
      );

      spans.add(TextSpan(text: text.substring(indexOfAli + 3, text.length)));

      return TextSpan(children: spans, style: style);
    }

    return TextSpan(text: text, style: style);
  }
}
