Interceptor class
Interceptor helps to deal with RequestOptions, Response, and DioException during the lifecycle of a request before it reaches users.
Interceptors are called once per request and response, that means redirects aren't triggering interceptors.
See also:
- InterceptorsWrapper, the helper class to create Interceptors.
- QueuedInterceptor, resolves interceptors as a task in the queue.
- QueuedInterceptorsWrapper, the helper class to create QueuedInterceptors.
