title: flutter- D8: Type com.dexterous.flutterlocalnotifications.utils.BooleanUtils is defined multiple times:
body: <p>I am pretty new at this so the question might be stupid but-
  I'm working on a flutter app and I'm trying to add notifications to it.
  Everything works fine, but when I add <code>'flutter_local_notifications: ^9.5.3'</code> under dependencies in the pubspec file, I get this error:</p>
  <blockquote>
  <p>...Documents/projectname/build/flutter_local_notifications/intermediates/runtime_library_classes_jar/debug/classes.jar:
  D8: Type com.dexterous.flutterlocalnotifications.utils.BooleanUtils is
  defined multiple
  times:...Documents/projectname/build/flutter_local_notifications/intermediates/runtime_library_classes_jar/debug/classes.jar:com/dexterous/flutterlocalnotifications/utils/BooleanUtils
  2.class...</p>
