Unfortunately, the plugin doesn’t support Java, Kotlin, Flutter nor XML syntax, 
making it completely useless for anyone in the Android development field.

I don’t normally use WP Blocks and so I could not figure out why this plugin broke
for certain code syntax (PHP -> HTML -> PHP for example) and why saving sometimes
broke the previously-saved syntax. Maddening. Then I switched back to the block 
editor. AHA! It works beautifully. That’s probably why it says “Block” in the plugin
name, duh. Thank you very much for this wonderful plugin. I love that we can also
upload our own prism.js files. Cool.
