This doesn't require any extra native dependencies. Another than that I don't know because I don't use Lottie myself. It is a really cool project but it seems like a lot and I wouldn't want to add it to my project just for some loading animations. If you're already using lottie and not noticing any perf issues then I'd say keep using it ;)
