When running the app, you will find 2 main.dart Choose the one with the flutter icon beside it

add check all component that is necessarily required and update all

a. Launch the "Microsoft Visual Studio Installer" from your start menu.

b. Select "Modify" for the instance of Visual Studio 2017 you have installed.

c. Under the "Summary" pane of the workload selector, click the "Desktop development with C++" expander (if it is collapsed)

d. Check the "VC++ 2015.3 v140 toolset (x86,x64)" optional feature.

[2] If you're attempting to build a UWP application, you should install Visual Studio 2015 Update 3, selection the UWP optional feature during setup.

[3] Finally, you may also upgrade your project/solution to the v141 Platform Toolset, which is the default for Visual Studio 2017.

Make sure your test file which has the driver does not contain any flutter-related imports.

so app_test should have nothing to do with flutter, only dart.
