java.lang.UnsupportedOperationException: Unexpected call: hashCode
Closed this issue · 9 comments

This error suddenly appeared. I think I had used .hashCode() before, but not sure.
I removed all my usages of .hashCode() and the error still occurs.

It seems to be because of a data class, which has certain contents in hashCode it did not expect. So indeed either you overridden hashCode in a data class, or something about your data class made it generate the hashCode in a different way I didn't anticipate 🤔
Do you know maybe which data class in your code could cause this? In any case I probably have to fix the first case (overridden hashCode in data class)
eggnstone commented
To my knowledge I don't override hashCode in my data classes, they are really only data containers, nothing more.
I do have interfaces that override hashCode and then the classes that implement them.
But I disabled all of them for testing and the error still occurred. Maybe I overlooked a place ...
wilkomanger commented
I see 🤔 Well, I'll add a test for explicitly overriding the hashCode in a data class, and maybe it fixes your case 👍
wilkomanger commented
Should be fixed with 341e31b, can you verify it works for you? If it does it means hashCode was overridden somewhere 😄
eggnstone commented
I checked again and temporarily removed every hashCode occurrence. Error persists.
I updated to 34... and the error still occurs :(
wilkomanger commented
I see 🤔 The repo is on Github right? Which one is it? Then I can look for suspicious data classes 😄
eggnstone commented
Yep, the Kotlin repo is https://github.com/eggnstone/DartFormatJetbrainsPlugin
But I pull only a few specific classes into https://github.com/eggnstone/dart_format
with https://github.com/eggnstone/dart_format/blob/master/dotlin.sh
which then also calls dotlin-compiler.
wilkomanger commented
Thanks! Found the issue, fixed it at e6d47a9, pretty sure it should work for you now, can you confirm?
eggnstone commented
Well, this error is gone but there's a new one :)
