+Demo applications used by the Dart & Flutter Developer Experience team.
+
+These applications consist of Dart & Flutter apps that are used for local
+testing of tools like Flutter DevTools, Flutter & Dart supported IDEs, and the
+Dart Analysis Server. Some apps may have also been used for user experience
+testing.
+
+There is no guarantee that these apps will be further maintained or kept up to
