Hi, ii think the Bug is due to flutter html but i dont know that what it exactly is happen

can reproduce code :

import 'package:dio/dio.dart';
import 'package:flutter/material.dart';
import 'package:flutter_html/flutter_html.dart';
import 'package:url_launcher/url_launcher.dart';

// ignore: must_be_immutable
class ShowPageR extends StatefulWidget {

   ShowPageR({Key? key}) : super(key: key);

  @override
  _ShowPageRState createState() => _ShowPageRState();
}
class _ShowPageRState extends State<ShowPageR> {

  @override
  // ignore: must_call_super
  void initState() {

    super.initState();
  }

var tt = r"""
