The repository is here: https://github.com/TimWhiting/syntax, It involves an ImplicitGetter with a record return type.
I tried simplifying the relevant code as follows, but this doesn't trigger the crash.
sealed class Test { Test._(); factory Test.a(Formals formals) = TestA; } sealed class ITest {} sealed class ITest2 extends ITest { Formals get params; } typedef Formals = (List<String>, String?); abstract class TestA extends Test implements ITest2 { TestA._() : super._(); @override (List<String>, String?) get params; factory TestA(final (List<String>, String?) p) = TestImpl; } class TestImpl extends TestA { @override final (List<String>, String?) params; TestImpl(this.params) : super._(); } void main() { final test = TestImpl((['a', 'b'], null)); print(test.params); }

…unboxed record return values Unboxing of records involves a more complex code, and such intrinsics would be similar to the normal code of the implicit getters.
