This function is available on all platforms because the call will also be on all
platforms soon. (currently only on cros/win)

See:

Also, I struggled to come up with a good name for this function, but this was
the best I could do...

Is the name from the ? : ternary operator? Maybe add a note in the comment
around line 177 like: 
* Works like a ternary operator. E.g. (value) ? trueLabel : falseLabel;

Also how about 
(offering an alternative name, not requiring that it change to this):
selectString(bool, string, string)

Done.
