Cannot convert null literal to non-nullable reference type.

Type parameter 'T' has the same name as the type parameter from outer type 'SparseMatrixStore<T>'

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

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

Dereference of a possibly null reference.

Argument of type '(int row, int col, T?)' cannot be used for parameter 'item' of type '(int row, int col, T data)' in 'void List<(int row, int col, T data)>.Add((int row, int col, T data) item)' due to differences in the nullability of reference types.

Nullability of reference types in value of type 'List<(int row, int col, T data)>' doesn't match target type 'List<(int row, int col, T? data)>'.

Possible null reference return.
