  • Fix pausing starting of main after the hot restart.
  • Updating bootstrapper for DDC library bundler module format + Frontend Server.

26.2.1 #

  • Add support for DDS APIs and serving Dart DevTools when no Chrome Debugger is available.

26.2.0 #

  • Add support for more service APIs over websocket connections when no Chrome Debugger is available.

26.1.0 #

  • pause now does not send a PauseInterrupted event in WebSocketProxyService as we didn't actually pause.

26.0.0 #

  • Bump SDK constraint to ^3.10.0
  • Added 'scriptUri' parameter to compileExpressionToJs
  • Fix an issue in reloadSources where a PauseInterrupted event was sent. - #61560

25.0.3 #

Bug Fixes: #

  • Fix issue in hot restart with the web socket where we didn't pass the reloaded sources path, resulting in a null assertion.

25.0.2 #

Bug Fixes: #

  • Fix issue where DDS would fail to initialize if DWDS already had existing clients.

25.0.1 #

Bug Fixes: #

  • Fix issue in hot restart where a hot restart with no changes followed by one with changes, a Future was completed again, resulting in a crash.

25.0.0 #

  • Implemented hot restart over websockets with multi window support.
  • Fix refresh race condition bug by adding an isolate destruction grace period.
  • Update a call to the package:shelf_web_socket webSocketHandler() function.

  • Rename FrontendServerDdcLibraryBundleStrategy.hotReloadSourcesUri to reloadedSourcesUri. The file that the Uri points to should now be updated for both a hot restart and a hot reload.

24.4.1 #

  • Implemented a WebSocket-based communication protocol that provides essential developer tooling (hot reload, service extensions) when Chrome debugger access is unavailable. - #2605

  • FrontendServerDdcLibraryBundleStrategy.hotReloadSourceUri is now expected to also provide the reloaded modules.

  • Refactored the injected client to use a reusable function for handling hot reload requests and responses over WebSockets.
  • Added support for breakpoint registering on a hot restart with the DDC library bundle format using PausePostRequests.

24.3.10 #

  • Disabled breakpoints on changed files in a hot reload. They currently do not map to the correct locations or are broken, so disable them for now. - #60186

24.3.9 #

24.3.8 #

  • Updated DWDS to include a boolean flag that enables debugging support only when set to true. #60289

24.3.7 #

  • The registered extension reassemble is now no longer called when calling reloadSources. Users should call reassemble using callServiceExtension.

  • callServiceExtension now checks the runtime for the list of registered service extensions. It also now throws a RPCError with RPCErrorKind.kMethodNotFound when a service extension is not found instead of throwing a JS evaluation error.

24.3.6 #

  • Bump minimum sdk version to 3.7.0
  • use 'compile js-dev' instead of directly invoking the ddc snapshot.
