How to Change width of element inside ListView?

I have a ListView with some items, but my problem is that the item inside the ListView will expand through the all-screen width, and I tried to use SizedBox and Container but it doesn't work for me. Here is my code:

  body: ListView.builder(
    itemCount: 10,
    itemBuilder: (ctx, index) {
      return SizedBox(
        width: 10,
        height: 10,
        child: Card(
          color: btnColor,
          child: Text(
            "Helo",
            // loremIpsum,
            style: TextStyle(color: Colors.black.withOpacity(0.6)),
          ),
        ),
      );
    },
  ),

I fixed my issue from this link:

body: ListView.builder(
        itemCount: 10,
        itemBuilder: (ctx, index) {
          return Row(
            children: [
              Container(height: 50, width: 50, color: Colors.black),
            ],
          );
        },
      ),

Just use Row inside the ListView
