how to avoid Space in ClipRrect - flutter

I'm trying to create wallpaper app, But instead of GridView I used wrap as it was easy for me to understand, But on using it there are spaces in between the wallpapers

SafeArea(
            child: SingleChildScrollView(
              child: Wrap(
                children: [
                  for (int i = 0; i < 24; i++)
                    Padding(
                      padding: const EdgeInsets.all(6.0),
                      child: ClipRRect(
                        borderRadius: BorderRadius.circular(20.0),
                        child: CachedNetworkImage(
                            imageUrl: top2Wall[i]['attributes']['src'],
                            width: 188),
                      ),
                    )
                ],
              ),
            ),
          )

Please refer to the image if you cant understand.

Solution

It is easier to deal with this using GridView as I’ve showed on last question of yours

 child: CachedNetworkImage(
      imageUrl: top2Wall[i]['attributes']['src'],
      width: 188, 
      height: X. your fixed image height,
      fit: BoxFit.cover,
),

And for spacing use

  child: Wrap(
          spacing: 12,
          runSpacing: 12,
