Dio Cache Interceptor is a Flutter/Dart package that adds HTTP caching capabilities to the Dio HTTP client. It supports multiple cache stores and respects standard HTTP caching directives such as Cache-Control and Expires, while also allowing customization to bypass these rules when needed. Ideal for improving app performance by reducing redundant network requests and minimizing data usage. The interceptor seamlessly integrates with existing Dio setups and works across all major platforms including Android, iOS, Web, macOS, Windows, and Linux.
