are exposed to JS as a
single ScrollView component, configured via the horizontal
boolean property.

getCommandsMap()
Subclasses of
ViewManager that expect to receive commands through UIManagerModule.dispatchViewManagerCommand(int, com.facebook.react.bridge.Dynamic, com.facebook.react.bridge.ReadableArray) should override this method returning the map
between names of the commands and IDs that are then used in ViewManager.receiveCommand(T, int, com.facebook.react.bridge.ReadableArray) method
whenever the command is dispatched for this particular ViewManager . |

getExportedCustomDirectEventTypeConstants()
Returns a map of config data passed to JS that defines eligible events that can be placed on
native views.

When set, fills the rest of the scrollview with a color to avoid setting a background and
creating unnecessary overdraw.

Tag used for logging scroll performance on this scroll view.
|
void |
setSendMomentumEvents(ReactScrollView view,
