Using windows 11 and Android studio, I created flutter app for Windows.

Using MSIX package, I created MSIX file.

When I upload MSIX file into Microsoft Store, I get the error message looking for the App Manifest file.

The App Manifest file should have all the app info.

First, I don't know how to create App Manifest file and how to populate the App Manifest file with all the required information.

I've read that it is generated automatically using the build under build windows folder, but I don't see it.

Once I have MSIX and the App Manifest, I don't know how to bundle it together.

I think I need to create .msixbundle file.

The problem is that I need to use Visual Studio to generate this bundle file.

I cannot open MSIX file in Visual Studio.

If I try to create the app package manually, then Microsoft Help says: "Note that MakeAppx.exe does not create an app package upload file (.appxupload or .msixupload), which is the recommended type of valid app package for submissions to Partner Center.
