Farcaster react native experts - what's the best way to do a text area with things like @ mentions (think a Casting input). Are there any serious problems with using a webview?

using a webview is fine just remember to unmount it so it doesn’t leak memory in the background

I’ve used pop-ups/tooltips to implement something similar. 

Webview should work fine as well, but if you want to have all mobile components - then a small tooltip type functionality would be better and unobtrusive while typing
