This still needs to be integrated into the Flutter Markdown renderer.
But the good news is that this works!
It currently requires network access to download the katex scripts. It
does NOT send the katex string to any server. The rendering is performed
in the app.
It kind of works. The main problem is that the webview shows itself and
doesn't disappear after taking a screenshot. Also, I'm having to use an
old form of the community flutter webview plugin as the official
"community" plugin, doesn't support screenshots.
Overall, not bad. It'll probably just be easier to fork the webview
completely and fix the issues I'm encountering.
on iOS; Trying to take a screenshot resulted in a crash.
