Cannot convert null literal to non-nullable reference type.

Nullability of type of parameter 'obj' doesn't match overridden member (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'left' of 'bool GeoJSONObject.Equals(GeoJSONObject left, GeoJSONObject right)' doesn't match implicitly implemented member 'bool IEqualityComparer<GeoJSONObject>.Equals(GeoJSONObject? x, GeoJSONObject? y)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'right' of 'bool GeoJSONObject.Equals(GeoJSONObject left, GeoJSONObject right)' doesn't match implicitly implemented member 'bool IEqualityComparer<GeoJSONObject>.Equals(GeoJSONObject? x, GeoJSONObject? y)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'other' of 'bool GeoJSONObject.Equals(GeoJSONObject other)' doesn't match implicitly implemented member 'bool IEquatable<GeoJSONObject>.Equals(GeoJSONObject? other)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'other' of 'bool Feature<TGeometry, TProps>.Equals(Feature<TGeometry, TProps> other)' doesn't match implicitly implemented member 'bool IEquatable<Feature<TGeometry, TProps>>.Equals(Feature<TGeometry, TProps>? other)' (possibly because of nullability attributes).

Nullability of type of parameter 'obj' doesn't match overridden member (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'left' of 'bool CRSBase.Equals(CRSBase left, CRSBase right)' doesn't match implicitly implemented member 'bool IEqualityComparer<CRSBase>.Equals(CRSBase? x, CRSBase? y)' (possibly because of nullability attributes).
