React-native: RTL apps with a horizontal scrollView

[hamidhadi]

In the info.plist, I changed the Localization native development region to 'fa' so my app direction is RTL.
ScrollView horizontal does not work fine.
I can't see the scroll indicator and can't scrolling.
If I change the Localization native development region to LTR languages, the scrollview works fine.
Is there anyway to solve this problem?

Same here, Horizontal ScrollView doesn't work properly in RTL Layout (on both iOS and Android)

Reproduction

Use RTLExample page in UIExplorer to apply RTL layout and then use horizontal ScrollView in <ScrollView> page

Additional Information

• React Native version: 0.40.0
• Platform: iOS, Android
• Operating System: MacOS

Anyone can help/contribute?

It's a bug and it breaks my app and a lot of good components like react-native-swiper and react-native-scrollable-tab-view that uses horizontal ScrollView.

Example:

This is my code:

<ScrollView horizontal>
  <View style={{ width: 150, height: 100, backgroundColor: '#12a19e' }}><Text>1</Text></View>
  <View style={{ width: 150, height: 100, backgroundColor: '#f45b21' }}><Text>2</Text></View>
  <View style={{ width: 150, height: 100, backgroundColor: '#640fe7' }}><Text>3</Text></View>
  <View style={{ width: 150, height: 100, backgroundColor: '#8f5e3e' }}><Text>4</Text></View>
  <View style={{ width: 150, height: 100, backgroundColor: '#f4bd15' }}><Text>5</Text></View>
  <View style={{ width: 150, height: 100, backgroundColor: '#137cf9' }}><Text>6</Text></View>
</ScrollView>

Preview:

Temporary fix:

<ScrollView
  horizontal
  style={{ flexDirection: I18nManager.isRTL ? 'row-reverse' : 'row' }}
>
   ...
</ScrollView>

In RTL layout you should use scrollToEnd() method to scroll to the first item

I tested this again on v0.43.2 and the iOS ScrollView works as expected, but the Android ScrollView still has this issue

This is a deal breaker, someone is on it?
