//
// In this case, we do it because we are trying to call internal methods of
// the tooltip code in order to test it. Normally, the state of a tooltip is a
// private class, but by using a GlobalKey we can get a handle to that object
// and by using "as dynamic" we can bypass the analyzer's type checks and call
// methods that we aren't supposed to be able to know about.
//
// It's ok to do this in tests, but you really don't want to do it in
// production code.
