HTTP/2 for Dart

Note: This is a work in progress and experimental.

See the API docs for more details and sample code.

Features and bugs

Please file feature requests and bugs at the issue tracker.


  • On connection termination, try to dispatch existing messages, thereby avoiding terminating existing streams.

  • Fix ClientTransportConnection.isOpen to return false if we have exhausted the number of max-concurrent-streams.


  • Switch all uppercase constants from dart:convert to lowercase.


  • More changes required for making tests pass under Dart 2.0 runtime.
  • Modify sdk constraint to require '>=2.0.0-dev.40.0'.


  • Fixes for Dart 2.0.


  • Strong mode fixes and other cleanup.


  • Removed use of new Function syntax, since it isn't fully supported in Dart 1.24.


  • Added an onActiveStateChanged callback to Connection, which is invoked when the connection changes state from idle to active or from active to idle. This can be used to implement an idle connection timeout.


  • Fixed a bug where a closed window would not open correctly due to an increase in initial window size.


  • The endStream bit is now set on the requested frame, instead of on an empty data frame following it.
  • Added an onTerminated hook that is called when a TransportStream receives a RST_STREAM frame.


  • Add errorCode to exception toString message.


  • Fixing a performance issue in case the underlying socket is not writeable
  • Allow clients of MultiProtocolHttpServer to supply [http.ServerSettings]
  • Allow the draft version 'h2-14' in the ALPN protocol negogiation.


  • Adding support for MultiProtocolHttpServer in the package:http2/multiprotocol_server.dart library


  • First version of a HTTP/2 transport implementation in the package:http2/transport.dart library


  • Initial version
