Needed the MyWidget example for snap with key to be stateful widget. It was giving an error that `currentState` was not a method of key. The docs for GlobalKey(https://api.flutter.dev/flutter/widgets/GlobalKey-class.html) says it only extends stateful widgets, i.e. ``` GlobalKey<T extends State<StatefulWidget>> class ``` Also, small typo of CamelCase on `snapOnTap`
