06:31 +46 ~3 -1: test/integration.shard/debug_adapter/flutter_adapter_test.dart: launch can run and terminate a Flutter app in noDebug mode [E]                                                        
  Expected: [
              'Launching lib/main.dart on Flutter test device in debug mode...',
              'topLevelFunction',
              'Application finished.',
              '',
              <a string starting with 'Exited'>
            ]
    Actual: [
              'material_color_utilities 0.2.0 (0.3.0 available)',
              'Got dependencies!',
              'Launching lib/main.dart on Flutter test device in debug mode...',
              'topLevelFunction',
              'Application finished.',
              '',
              'Exited.'
            ]
     Which: at location [0] is 'material_color_utilities 0.2.0 (0.3.0 available)' instead of 'Launching lib/main.dart on Flutter test device in debug mode...'
