Most interesting apps tend to use custom Android views, layouts and behaviors to create a unique, but consistent look and feel. Flutter can do the same. There is not much difference, except that Flutter strives to do the unique part better. On the Windows desktop your application must be coherent with other applications, since they share a big screen, or rather a workspace. Either way you want to adhere to the design language of the OS, because it tends to work better than what you can come up with, and also provides familiarity. On Android you don't have to use the prebuilt widgets to adhere to the material design. Flutter also comes with widgets that look and feel very similar to the Android and iOS ones, so you don't have to reinvent the whole wheel.
