How To Constraint The Width Of A GridView Widget In Flutter

I've been trying for two days to add a fixed width to a Grid View in flutter but I couldn't.

I tried adding width or Box Constraint to a parent container but it didn't work.

I am building a web app so the screen width is often wider than a smartphone's.
this is how I want it to look like:

fixed width for GridView in flutter example

Objective:

constraint the width of the GridView Widget to have a max width of 1000 as an example.

Edit:

if you face any issue with centering the parent container just rap it with a Center widget and that should work

Here you can use crossAxisCount property to add no of items in row. Then give the fixed to its child by wrapping it in a container.

  Container(
        width: 100, // HERE YOU CAN ADD THE WIDTH
        child: GridView.builder(
            physics: NeverScrollableScrollPhysics(),
            shrinkWrap: true,
            itemCount: list.length,
            scrollDirection: Axis.vertical,
            gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
              childAspectRatio: 1,
              crossAxisCount: 4, // HERE YOU CAN ADD THE NO OF ITEMS PER LINE
              mainAxisSpacing: 5,
              crossAxisSpacing: 5,
            ),
            itemBuilder: _getListItemTile))
