A token refresh library for dart. This package extends fresh_dio by checking a token before sending a request.
This package should be compatible with you code, that already uses fresh_dio. In the most case you have to
change Fresh.oAuth2(...) to FreshNext.oAuth2(...) and mix your OAuth2Token with TokenProtocol or use
a OAuth2TokenNext class.
By default fresh_dio will always send a request, if a response code is 403, then dio tries to refresh a token and
resends a same request with new token. This packages tries first to validate the token, if token is invalid, then a new
token will be requested. Only after that fresh_dio send a request to server.
This implementation solve the case, when the user sends a request with MultipartFile with invalid token. Because
the MultipartFile can be read only one time, by second sending the error will be thrown and user
receives Can't finalize a finalized MultipartFile message. Sending a request with invalid token costs internet
bandwidth, so it's nice if we can avoid first request with invalid token.
