Issue Info

Hi. You have this example for queued interceptor.

https://github.com/flutterchina/dio/blob/a4392ff8412bfe1e3e86ae45f81fe1fc117bc56e/example/lib/queued_interceptor_crsftoken.dart

Issue Description and Steps

onError you are requesting new token with different Dio client called tokenDio
https://github.com/flutterchina/dio/blob/a4392ff8412bfe1e3e86ae45f81fe1fc117bc56e/example/lib/queued_interceptor_crsftoken.dart#L48

Does this mean that dio client is paused?

If the main dio client is paused why do you retry the failed request with dio client
https://github.com/flutterchina/dio/blob/a4392ff8412bfe1e3e86ae45f81fe1fc117bc56e/example/lib/queued_interceptor_crsftoken.dart#L53

Looks a little bit confusing.

Could you clarify why it works?
Why we can do retry with the same client but have to request token with different one?

+1 for clarification

Agreed, we need more clarification on this.
The example code actually causes dead lock, which seems a design flaw to me:
