Dart Analyzer Error In Flutter Using IntelliJ

[psycry]

I've removed personal/app identifying information from the stack trace below, but randomly I'm getting this error in IntelliJ after updating flutter earlier today, reproducible on a mac using the beta branch (as well as dev) with the current IntelliJ flutter plugin (also updated today, if there is another board for that particular plugin feel free to move this to the correct queue or let me know where to submit for the plugin itself if you don't mantain it):

13:24 Dart Analyzer Error
Encountered a Dart Analysis Server error.
Open issue submission form?

It also seems to be doing auto-complete way slower than usual. It seems to have coincided with an upgrade and isn't consistent.

I also noticed I had to re-install dart/flutter lost the path during the upgrade and it took a few restarts to fix it though this could be unrelated.

It's happening fairly consistently and every time it does I have to restart intellij in order for the code completion to work again.

I've also confirmed this is not isolated to ticker provider:

@psycry Not that it's very helpful, but instead of restarting the whole nine yards, you can just restart the Analyzer. In Android Studio it's a small circular red icon in the upper left corner of Dart Analysis window.
I have tens of these exceptions per day :-(

[psycry]

Thanks ill try that instead, how long has it been doing this? I dont update religiously but it hasnt been that long.

Is there another bug following it? I couldnt find one so thats why i cut this one.

@psycry it has been doing this for a couple of weeks already
