Comparison method violates its general contract! error across many Android tests. #103230
Description
Current status: #103230 (comment)
The root of this issue is Groovy dynamic dispatch.
The flutter teams current plan for this bug is to migrate all of our groovy code to kotlin as defined in #121541 which has the added benefit of removing a language from the set maintainers need to know. This is aligned with the android teams recommendations.
This bug might be solved by removing the groovy dynamic dispatch called code in #114660. This pr was supposed to do exactly that but instead converted the code to kotlin and still uses groovy dynamic dispatch.
Another possible work around without migrating code to kotlin is to use compileStatic which converts the groovy code to bytecode and restricts the use of incompatible code.
