Seeing this on flutter beta/3.12.0-1.1.pre with dwds 19.0.0:

Which for v19.0.0 is

webdev/dwds/lib/src/services/chrome_proxy_service.dart

Line 1111 in e887316

final firstArgValue = event.args[0].value as String;

And at HEAD: https://github.com/dart-lang/webdev/blob/master/dwds/lib/src/services/chrome_proxy_service.dart#L1364

How long to merge the issue that solves the problem? If it takes that long I have to downgrade the flutter version :(

[aleliottasyn]

I see that the bug is fixed in 19.0.2, but flutter keeps downloading the buggy version(19.0.1+1). So I'm not able to update my app. Please let me figure out how to fix this. @elliette

@aleliottasyn this fix is available in Flutter beta 3.14.0-0.2.pre, I would recommend switching to that release in order to unblock the debugging workflow. Given the current impact of this bug, and the cost of releasing hotfixes, I don't think we will be considering hotfixing this at this time.
