explicit null param

androidui · 2022-09-13T12:35:27.637Z

is there a way to specify an explicit overload for `null` ? eg foo(object_a); // object overload foo(null); // null overload eg, equivilant to C++'s `std::nullptr_t` specifically to avoid ```cs foo(C_A); foo(C_B); foo(null); // ambigous overload ```

You can't have an overload specifically for null, although you can have an overload without the parameter entirely.

Rename

SetChildValueNull

SetChildValueNull

SetChildValueNull

SetChildValueNull to

SetChildValue

SetChildValue

SetChildValue

SetChildValue, and just don't pass anything to it. If you need to check for null at runtime instead, then you'll need to do it in every function.
