Bear in mind that this is a compiler-only thing - once compiled, all strings are back to being normally nullable.

If you have function declaration: void M(string s) { }, the idea is that you can be assured that s is going to be a not-null string. Because, where you call that function, you will be warned if you try M(null), or
string? s;
M(s);

The only times you are expected to test for null are:
1) If you receive a string? from a function. You should check for non-null before you use it.
2) Even if you have a not-null string parameter, if that method is external facing, another project may still send a null string

(obviously this all works for any reference type, not just strings...)

Does that help?
