Flutter build web failing due to EventStreamProviders

[rnp0728]

(editor update: see below - we've reverted the 2.4.2 publish of this package).

---

While running flutter build web the following error comes up, until yesterday the builds are working properly. The new update on web_socket_channel:2.4.2 affected this error. We are not using this package directly but some of the packages are dependent on it.

ERROR LOGS :

Good!

Hi - these most recent issues were likely caused by the release of 2.4.2, which adjusted the dep on package:web in ways that weren't compatible. We're retracted that release - people who have it pinned explicitly will still see it, but it won't be visible to new version solves.

Also, it looks porting this package to use package:web was (unintentionally) a breaking API change - some of the API types exposed from the package are different. We'll track work to address that in a separate issue, but we may revert the 2.4.x range of this package back to using dart:html, and publishing a new 3.0.0 version of this package that's based on package:web.

dart-lang/http#1655 becomes relevant again because 2.4.3 is once-again reliant on pkg:web 0.4.0 or higher, and Flutter has 0.3.0 pinned. Flutter still won't be able to use 2.4.3.

[devoncarew]

This is the same situation for other packages that Flutter pins however. You need to use dependencies that are compatible with the versions that Flutter was built with. For package:web, that's:

• stable - pinned web to 0.3.0
• beta - pinned web to 0.4.0
• main - the pin's been removed; the few uses of package:web were in-lined into the framework
