PlayGamesPlatform.Instance.localUser.Authenticate((bool success) =>
In the code snippet above what does this "=>" mean?
I have been unable to find any references for this

Its not always obvious however in this case its part of making a lamda peice of code, so rather than
PlayGamesPlatform.Instance.localUser.Authenticate(something);
where something is declared as
bool something()
{
.. code ..
}
you can do something on the fly with
PlayGamesPlatform.Instance.localUser.Authenticate((bool success) => { .. code .. } );
