React-native-ui-kitten: Unusably slow

[isaaclem]

First of all I must express my very good impression for the well written docs at https://akveo.github.io/react-native-ui-kitten/docs/guides/getting-started#getting-started

I was following the guide by creating a HomeScreen and a DetailsScreen, working together using React-navigation, and below is the GIF created to show how slow it is to render on screen.

After loaded 100%, clearly you can see that I have to wait close to 15 secs to see the HomeScreen being rendered on screen, am I the only one facing this issue?

Same problem

Same problem here. the sample app Kitten Tricks also takes around 6-10 secs to load on low-end Android phones (tested on _Redmi 8, Android 10_), high-end Android phones such as _Google Pixel 3 XL (Android 10)_ takes around 3 secs. Anyway to optimize this for low-end phones?

Have you tried compiling your mapping files?

You may use the same guide to faster it. We didn't update Kitten Tricks to follow that because it may run both Expo and Bare RN environments.

Hi artyorsh, thanks for replying. I followed the guide and it's loading faster now. Thanks for the great UI library!
