Answer 1

我认为,这是你回顾的:

Answer 2

说明如何与Dart HtmlE罪羊阶级打交道。

const HtmlEscape htmlEscape = HtmlEscape();
String unescaped =  Text & subject ; // The text you want to convert
String escaped = htmlEscape.convert(unescaped);
print(escaped); // Text &amp; subject

Using flutter_html to preview with HTML template.

import  package:html/parser.dart  as htmlparser;
import  package:html/dom.dart  as dom;
...
String htmlData = """<div>
  <h1>Demo Page</h1>
  <p>This is a fantastic product that you should buy!</p>
  <h3>Features</h3>
  <ul>
    <li>It actually works</li>
    <li>It exists</li>
    <li>It doesn t cost much!</li>
  </ul>
  <!--You can pretty much put any html in here!-->
</div>""";
dom.Document document = htmlparser.parse(htmlData);
/// sanitize or query document here
Widget html = Html(
  document: document,
);
