flutter html widget code example

Example: flutter html

This plugin doesn`t have any issue, I just created a sample with your HTML and it works fine. Try to replace with below snippet and see if that works.

dependencies:
  flutter_html: ^0.8.2
and imports and code to render html

import 'package:flutter_html/flutter_html.dart';
import 'package:html/dom.dart' as dom;


 body: new Center(
            child: SingleChildScrollView(
              child: Html(
                data: """
                <div>Follow<a class='sup'><sup>pl</sup></a> 
                  Below hr
                    <b>Bold</b>
                <h1>what was sent down to you from your Lord</h1>, 
                and do not follow other guardians apart from Him. Little do 
                <span class='h'>you remind yourselves</span><a class='f'><sup f=2437>1</sup></a></div>
                """,
                padding: EdgeInsets.all(8.0),
                onLinkTap: (url) {
                  print("Opening $url...");
                },
                customRender: (node, children) {
                  if (node is dom.Element) {
                    switch (node.localName) {
                      case "custom_tag": // using this, you can handle custom tags in your HTML 
                        return Column(children: children);
                    }
                  }
                },
              ),
            ),
          )
