          home: new Scaffold(
              body: new Markdown(null, markdownData1,
                  syntaxHighlighter: new DartSyntaxHighlighter(SyntaxHighlighterStyle.lightThemeStyle()),
                  onTapLink:

          )
      );
  }
  

• 6. Adjust your code for better performance.
• 7. Enjoy!

Tips

• To use UIWidgets, Unity version must be larger than 2018.3

• If the markdown string is too long, it would take much more time to parse and render, so async operation is needed and a Dispatcher script is provided to handle this situation

  buildThread = new Thread(() =>
  {
      try
      {
          Stopwatch sw = Stopwatch.StartNew();
          if (nodes == null)
          {
              nodes = document.parseLines(lines.ToList());
          }
  
  
          if (widget.onParsed != null)
          {
              widget.onParsed(widget.id, nodes);
          }
  
  
          var elements = builder.build(nodes);
  
          // make the callback running on the unity main thread
          Dispatcher.Invoke(() =>
          {
              updateState(elements);
          });
  
  
          sw.Stop();
          Debug.Log(sw.ElapsedMilliseconds / 1000f);
      }
      catch (ThreadAbortException e)
      {
          Debug.Log(e.Message);
      }
  });
  

• Also could use in-app webview to handle URL click event to replace Application.OpenURL for viewing web page in your unity application.
