You can encapsulate any widget in your code with a new widget called (Visibility), this is from the yellow lamp at the very left side of the widget that you want it to be in-visible

example: say you want to make a row invisible:

1. Click in the lamp and choose (Wrap with widget)
2. Rename the widget to Visibility
3. Add the visible property and set it to false

4. The Child of the newly created widget (Visibility Widget) is the Widget that you want it to be invisible

             Visibility(
                 visible: false,
                 child: Row(
                   crossAxisAlignment: CrossAxisAlignment.start,
                   children: [
                     SizedBox(
                       width: 10,
                     ),
                     Text("Search",
                       style: TextStyle(fontSize: 20
                       ),),
                   ],
                 ),
               ),
