findInstanceMethod method
The instance method name, searching this enum then its mixins.
Same order as InterpretedEnumValue.get resolves one — own members first, then mixins in reverse declaration order so the last applied wins.
Implementation
InterpretedFunction? findInstanceMethod(String name) {
final own = methods[name];
if (own != null) return own;
for (final mixin in mixins.reversed) {
final fromMixin = mixin.methods[name];
if (fromMixin != null) return fromMixin;
}
return null;
}
