Middleware for the http package that transparently retries failing requests.

To use this, just create an RetryClient that wraps the underlying http.Client:

import 'package:http/http.dart' as http;
import 'package:http_retry/http_retry.dart';

main() async {
  var client = new RetryClient(new http.Client());
  await client.close();

By default, this retries any request whose response has status code 503 Temporary Failure up to three retries. It waits 500ms before the first retry, and increases the delay by 1.5x each time. All of this can be customized using the new RetryClient() constructor.


  • Support the latest pkg:http release.


  • Set max SDK version to <3.0.0, and adjust other dependencies.


  • Update SDK version to 2.0.0-dev.17.0.


  • Add a whenError() parameter to allow requests to be retried when they encounter networking errors.


  • Initial version.
