Question about #nullable enable

[tranb3r]

Hi,

The generated code for ObservableProperty has the #nullable enable directive.
Does it mean that the code where the property field is defined also has to have the same directive in order to work?

Example:

[ObservableProperty]
private string _name;

private void Test()
{
    if (Name == null)
    // ....
}

This code generates a warning in visual studio: Expression is always false.
But if _name is not initialized, Name is null when testing it, and at runtime the condition returns True.

So, can I safely assume that the generated code will work, even if visual studio shows warnings ?

That is correct, you're getting the warning because you've marked the property as not nullable. You can either ignore the warning (since the property can in fact be null), or enable nullability annotations in that file (or in your whole project, if possible).
