How to set code block highlighting?

[zundaren]

This library is great, but I've encountered a problem。How to set code block highlighting? Is it necessary to provide a function to handle it myself and then return it to the internal rendering system for further rendering?

For code block highlighting you must provide a function to handle it yourself. You can do this by implementing the MarkdownBuilderDelegate.formatText method, it receives plain code text and must return a fully styled TextSpan for the internal rendering system to display.
