Nullable lists are not being mapped properly.

[smotastic]

Nullable lists are not being mapped properly.
My Model contains: List<String>? values;
Generated mapper contains: values: entity.values.map((e) => e).toList()
which results in error "The method 'map' can't be unconditionally invoked because the receiver can be 'null'"

Shouldn't it be values: entity.values!.map((e) => e).toList()
