Flutter Query is a state management package for fetching, caching, and synchronizing server data with automatic handling of loading, error, and success states. Inspired by TanStack Query, it simplifies data fetching in Flutter apps by providing declarative APIs, background updates, and built-in cache invalidation. It supports all major platforms and integrates seamlessly with Flutter’s reactive ecosystem. The package reduces boilerplate and enhances performance through intelligent caching strategies and automatic refetching.
