had to revert to 5.2.0 because of this, I am guessing this is due to #49928 ?

Please revert to 5.2.0

See flutter/engine#38114

dart-archive/collection#217 that added elementAtOrNull landed 6 months ago, and was pulled into Dart SDK soon after. I would expect that 6 months should be enough to pull package:collection into Flutter. But if it is not, the solution is to restrict package:analyzer version.

[scheglov]

Ah, I see. package:analyzer should require at least collection: ^1.17.0.
My bad. I will fix it.

[scheglov]

I retracted analyzer 5.3.0 from Pub.
I guess you will need to do dart pub upgrade again, maybe removing .dart_tool/package_config.json.
This should get you analyzer 5.2.0 again.
I have never done this before, so if you know better, please advise other people here.

[scheglov]

I updated https://dart-review.googlesource.com/c/sdk/+/274086 to re-publish analyzer 5.3.1 with correct collection: ^1.17.0. I probably will not publish it until tomorrow when more people in the office.

In my testing this is fixed. As my testing involves building up a project from scratch I'm unsure what is required to downgrade a project that has the retracted version. I'm hoping a flutter pub upgrade will do the right thing.
