Summary: For a very long time, iOS has supported the `contentOffset` property but Android has not: https://github.com/facebook/react-native/issues/6849 This property can be used, primarily, to autoscroll the ScrollView to a starting position when it is first rendered, to avoid "jumps" that occur by asynchronously scrolling to a start position. Changelog: [Android][Changed] ScrollView now supports `contentOffset` Reviewed By: mdvacca Differential Revision: D21198236 fbshipit-source-id: 2b0773569ba42120cb1fcf0f3847ca98af2285e7
