Yeah Flutter seems like the winner for my Project. I think the fact that I've worked with it in the past, and that it feels very react-y in some ways just makes it a lot nicer for me.
Yeah I've looked through the website and it seems pretty good. I think being able to use it with vanilla React is really appealing to me, especially because (if I'm not mistaken) I can use any normal library I'm familiar with (such as tailwind)?
I'm assuming this would cost a fair bit then? Also, what do you use to sync the files from your devices to the servers?
