Blank screen if any other idget is used as the root in the build method

When a column is used in place of a Listview in a listview, the UI does not render.

this occurs at the getMainListViewUI() function

It is simple if we used list view then we set inside expand or some proper height or width we need to set. if you need to add a column then column child does not have an expanded widget. I guess you can understand.
