☝️ I did a little testing on this earlier, and it turns out my initial query was extremely naive.. I began to notice significant lag with each keystroke at around 150 KB of text in a BasicTextField 😄

would love to hear if anyone has written a custom TextField implementation that handles large amounts of text, or has any advice 🙏

The demo has a text / code editor. I’d look there first. I assume a code editor would be able to handle large amounts of text.

the demo is where I found the comment // TextField isn't efficient for big text files, we use it for simplicity

this was in the Notepad demo, however the code editor is different altogether.. it is read-only, so it uses Text to display lines from an immutable string

I’d take this to the #compose channel. You’ll probably get more traction.

If you're planning on using it for any sort of "real" editing, it would really need its own component that can do proper text windowing without loading the whole thing into memory.
