App crashes when using percentage styles

Hi, I'm trying to use the library but it suddenly crash when I use percentage styles.
Please see the snack below (it's the same example given in README):
https://snack.expo.io/@lrnz09/estylesheet-percentage-crash
I'm on 0.8.1 but it crashes all the same?
@AnthonyLamot could you show Expo link or source code?
@vitalets was following a tutorial (https://github.com/EQuimper/youtubeMeetupAppReactNativeNode) and was making my own version of this file: https://github.com/EQuimper/youtubeMeetupAppReactNativeNode/blob/master/meetupme-mobile/src/screens/home/components/styles/MyMeetupsList.js
I switched back to ESS 0.0.4 cause I saw the guy who created the tutorial was using that one without issue.
I see that expo-sdk-16 from the example uses RN 0.43.2 that does not support percent values natively. The support was added in RN 0.44 and EStyleSheet started to proxy pure percents in #32 since v0.5.0.
Now I understand that moving to native percents was not done properly. Because many developers are using earlier versions of RN <= 0.43 and the change broke backwards compatibility.
Currently I see 3 options:
- Check the RN version in runtime and proxy percent values only if version > 0.43. But I did not find the way to detect RN version. And it seems RN developers intentionally do not provide it.
- On app start make short runtime check is native percents are supported or not. I need to check will it have any performance issue.
- Do nothing, just clarify in docs that using percents with RN <= 0.43 requires EStyleSheet 0.4.0. Because RN already go far from 0.43 and made 10 releases.
Cool. Honestly I'd go with option 3. I'll update my RN version in this project. ๐
Ok! Let me know if it's ok after upgrading RN.
I got it to work with:
"dependencies": {
"axios": "^0.17.1",
"eslint": "^4.17.0",
"expo": "^25.0.0",
"react": "16.2.0",
"react-native": "https://github.com/expo/react-native/archive/sdk-25.0.0.tar.gz",
"react-native-extended-stylesheet": "^0.8.0",
"react-navigation": "^1.0.3"
},
Hope that helps @vitalets !
