Initialize the route-pattern matcher before creating a Data Router or static
handler with future.unstable_routePatternMatching enabled. Import from
react-router/route-pattern and call this once during application startup.
Server and browser applications must each preload their own matcher.
The matcher is statically imported by this module. Tree-shaking bundlers can remove it from applications that do not use this function. Initialization is synchronous, and repeated calls are safe.
function unstable_preloadRoutePattern(): void
No return value.
