 * Returns a navigator that automatically injects matched routes and renders nothing when there are no children.
 * Return type with `children` prop optional.
 *
 * Enables use of other built-in React Navigation navigators and other navigators built with the React Navigation custom navigator API.
 *
 * @param Nav - The navigator component to wrap.
 * @param processor - A function that processes the screens before passing them to the navigator.
 * @param useOnlyUserDefinedScreens - If true, all screens not specified as navigator's children will be ignored.
 *
 *  @example
 * ```tsx app/_layout.tsx
 * import { ParamListBase, TabNavigationState } from "@react-navigation/native";
 * import {
 *   createMaterialTopTabNavigator,
 *   MaterialTopTabNavigationOptions,
 *   MaterialTopTabNavigationEventMap,
