function Helpers::getPreviousArrowFunctionIndex

* Move back from the stackPtr to the start of the enclosing scope until we * find a 'fn' token that starts an arrow function, returning the index of * that token. Returns null if there are no arrow functions before stackPtr. * * Note that this does not guarantee that stackPtr is inside the arrow * function scope we find! * *

Parameters

File $phpcsFile: * @param int $stackPtr * @param int $enclosingScopeIndex * * @return ?int
