Interceptor method has been changed


onRequest: (request, handler) {
print("${request.method}
return handler.next(request);
},
onResponse: (response, handler) {
print("${response.data}");
return handler.next(response);
},
onError: (error, handler) {
print("${error.message}");
return handler.next(error);
},
));
