// This file uses "as dynamic" in a few places to defeat the static
// analysis. In general you want to avoid using this style in your
// code, as it will cause the analyzer to be unable to help you catch
// errors.
//
// 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.
