Nullability of reference types in type of parameter 'type' of 'object TypeResolver.Resolve(Type type)' doesn't match implicitly implemented member 'object? ITypeResolver.Resolve(Type? type)' (possibly because of nullability attributes).

Dereference of a possibly null reference.

Possible null reference return.

Non-nullable field '_context' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Non-nullable field '_spinnerColumn' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Non-nullable property 'Filter' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'value' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.
