Hey this came in really late for the 3.50 beta to stable promotion so it will have to wait for the first patch version. |

Issue Link:

Also reported on the 3.50 beta: #190436 (comment)
Impacted Users:
Flutter web developers debugging large apps on Chrome/IDEs.
Impact Description:
Rolls dwds from 27.1.3 to 27.2.1 (landed on master in #195932)
For large web apps,
flutter run -d chromefails with:DWDS stops waiting for Chrome to respond to
Debugger.enableafter about 20 seconds (4 attempts of 5 seconds each).Chrome takes longer than that for large apps.
A fix in DWDS 27.2.1 updates this logic to send requests every 5 seconds for 3 minutes, stopping whenever any connection completes or the connection is closed.
Changelog Description:
dart-lang/webdev/2883:
flutter run -d chromefails to connect to the web debug service with aTimeoutExceptionfor large web apps.Workaround:
None on 3.5. I've asked users to use
flutter channel master.Risk:
What is the risk level of this cherry-pick?
The only new changes in this version (besides this fix) are a new optional
deprecatedJsInteropparameter and some other low-risk bug fixes.Test Coverage:
Are you confident that your fix is well-tested by automated tests?
Tets added to (
pkg/dwds/test/integration/webkit_debugger_test.dartin the Dart SDK).Validation Steps:
flutter run -d chromeon a large web app where Chrome takes over 20s to respond toDebugger.enable(see bugs for example apps).
