The @metamask/geolocation-controller package provides a centralized way to manage geolocation requests with built-in caching and request deduplication to avoid redundant API calls. Developers building MetaMask extensions or Ethereum applications can use this controller to efficiently retrieve and cache user location data while minimizing network overhead. The TTL (time-to-live) caching ensures location data doesn't become stale while deduplication prevents multiple simultaneous requests for the same information.
