my question might sound a bit off but how to make this thing ? i'am not sure what is called i'm sorry

CodePudding user response：

It is a widget or combination of widgets. You can use the code below and then position it at that point

SizedBox(
width 40,
child: Divider(height: 3, thickness: 3,color: Colors.grey),
),

That is the quickest solution I could come up with. Alternatively you can use a Row() then look for such a line icon and have it as the child. Of course setting the crossAxis to center
