How to reduce Gridview.builder default height

Question

I have used GridView.builder to show API data with below code.

GridView.builder(
    shrinkWrap: true,
    physics: ScrollPhysics(),
    itemCount: snapshot.data!.items.length,
    gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
      crossAxisCount: 2,
      childAspectRatio: 1 / .3,
    ),
    itemBuilder: (context, index) {
      return InkWell(
        onTap: () {},
        child: CategoryItem(categoryItem: snapshot.data!.items[index],
        ),
      );
    },
  ),

Here Now my data length is 4 only. when it increases then data will be scrollable. And that working fine But thing is, I want to get resizable height with data length. It takes a default height which is not compatible.

Is there any way to reduce default height or customize it?

Thanks in advance.

Getting below output :

wrap it with container, you can set height container

As specified in this response, the key is childAspectRatio. The child height is reduced when you're increasing childAspectRatio.

For instance try to set childAspectRatio: 5

GridView.builder(
    shrinkWrap: true,
    physics: ScrollPhysics(),
    itemCount: snapshot.data!.items.length,
    gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
      crossAxisCount: 2,
      childAspectRatio: 5,
    ),
    itemBuilder: (context, index) {
      return InkWell(
        onTap: () {},
        child: CategoryItem(categoryItem: snapshot.data!.items[index],
        ),
      );
    },
  ),
