FetchInterceptor class abstract

Base class for FetchBloc interceptors.

Interceptors run in a pipeline around network calls:

  1. onRequest chain (sorted by priority, lowest first)
  2. Network call (Dio)
  3. onResponse chain (reverse order) OR onError chain

Key points:

  • Interceptors run AFTER cache lookup and coalescer check
  • They only execute for actual network calls, not cache hits
  • onRequest runs in priority order (lowest first)
  • onResponse/onError run in reverse order (highest priority last)
