## Description This PR replaces `LogicalKeySet` by `SingleActivator` in one of the Shortcuts example. According to [LogicalKeySet documentation](https://api.flutter.dev/flutter/widgets/LogicalKeySet-class.html) : "prefer [SingleActivator](https://api.flutter.dev/flutter/widgets/SingleActivator-class.html) when possible, whose behavior more closely resembles that of typical platforms". ## Related Issue Related to [LogicalKeySet Not Working on Linux Environment](https://github.com/flutter/flutter/issues/156806). ## Tests Adds 1 test.
