+**contentContainerStyle** style
+
+These styles will be applied to the scroll view content container which wraps
+all of the child views. Example:
+
+**horizontal** bool
+
+When true, the scroll view's children are arranged horizontally in a row instead of vertically in a column. Default: `false`.
+
+**onScroll** function
+
+Fires at most once per frame during scrolling. The frequency of the events can be contolled using the `scrollEventThrottle` prop.
+
+**scrollEnabled** bool
+
+When false, the content does not scroll. Default: `true`.
+
+**scrollEventThrottle** number
+
+This controls how often the scroll event will be fired while scrolling (in
+events per seconds). A higher number yields better accuracy for code that is
+tracking the scroll position, but can lead to scroll performance problems.
+Default: `0` (the scroll event will be sent only once each time the view is
+scrolled.)
