/**
 * On Android, Props are derived from a ViewManager and its ShadowNode.

 * - Nearly all component ViewManagers descend from BaseViewManager,
 * - and BaseViewManagers' ShadowNodes descend from LayoutShadowNode.
 * - Also, all components inherit ViewConfigs from UIManagerModuleConstants.java.
 *
 * So, these ViewConfigs are generated from LayoutShadowNode and BaseViewManager.
