// LocalizationClassSingeton.of(appContect)!.loremIpsum 
// in places outside the widgets such as the Models.
// That also means that to test the models we use a MaterialApp
// wrapper in test to pumpwidget with child widget being 
// anything to insert the navigatorKey parameter and 
// localizations as then after the pump of widgets we 
// have the appContext global filled and then can 
// test the model stuff that has localizations.

// if using routes u need something different
// scaffoldMessengerKey is used in MaterialApp.routes
final scaffoldMessengerKey = GlobalKey<ScaffoldMessengerState>();

// Then
