Adding space between containers in a listview

i’m new to flutter and i’m trying to add some space between containers in a listview, literally tried everything but failed at it, I want to divide them containers for a better visualization of the items inside of the list, thanks in advance!

Code:

body: Column(
  children: <Widget>[
    Expanded(
      child: ListView.builder(
        padding: EdgeInsets.all(15),
        itemCount: 6,
        itemBuilder: (BuildContext context, int index) {
          return Row(
            children: [
              SizedBox(
                width: 70,
                child: AspectRatio(
                  aspectRatio: 0.88,
                  child: Container(
                    padding: EdgeInsets.all(22),
                    decoration: BoxDecoration(
                      color: Color(0xFFF5F6F9),
                      borderRadius: BorderRadius.circular(15),
                    ),
                    child: Image.asset(
                      'assets/syringe.png',
                    ),
                  ),
                ),
              ),
              SizedBox(width: 20),
              Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  Text(
                    "Type d'analyse",
                    style: TextStyle(color: Colors.black, fontSize: 16),
                    maxLines: 2,
                  ),
                  SizedBox(height: 10),
                  Text.rich(
                    TextSpan(
                      text: "Date: ",
                      style: TextStyle(
                          fontWeight: FontWeight.w600,
                          color: kPrimaryColor),
                    ),
                  ),
                ],
              ),
            ],
          );
        },
      ),
    )
  ],
),

>Solution :

Use ListView.separated instead of ListView.builder

It works exactly the same but with the added separatorBuilder parameter. Which could be something like

  separatorBuilder: (BuildContext context, int index) => const Divider()
