// 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.
