I want to create a text box that ables users to type messages. How do I let them change the fonts style of their message?
You mean, FontTypeface? The documentation says it is only available in the Designer, not blocks.
Maybe this extension might help?
If I use Times New Roman as an example, I have to upload a .ttf file.

Currently MIT App Inventor does not support custom font typeface but maybe in future you will find this GSoC project in MIT App Inventor.
Thank you for respond
Or this (which also work with Companion):
I think your modified extension should work on devices Android > 9.
I'll replace it. Thank you.
See number 3: Set custom fonts for your components dynamically.
It should work on all Android versions.
