listview.builder inside listview.builder

I created Cart page on my Marketplace application, but I'm getting struggle to make a list of products on cart that grouped - based on the market that sells it. I can make a list of the shops with ListView.Builder. What should I do to add the product on every market list?
I tried to use ListTile and it is working, but I don't think that's a good idea since I should show pictures e. g. counting button etc. I give an UI here.

This is my current code:

ListView.builder(
          itemCount: _cKeranjangProduk.list.length,
          scrollDirection: Axis.vertical,
          itemBuilder: (context, index) {
            KeranjangProduk keranjangProduk = _cKeranjangProduk.list[index];

            Toko toko = Toko(
                nama_toko: keranjangProduk.nama_toko,
                id_toko: keranjangProduk.id_toko);

            return SizedBox(
              width: MediaQuery.of(context).size.width,
              child: Container(
                margin: EdgeInsets.fromLTRB(
                  10,
                  index == 0 ? 16 : 8,
                  10,
                  index == _cKeranjangProduk.list.length - 1 ? 16 : 8,
                ),
                decoration: BoxDecoration(
                  borderRadius: BorderRadius.circular(5),
                  color: Colors.white,
                  boxShadow: [
                    BoxShadow(
                      offset: Offset(0, 0),
                      blurRadius: 6,
                      color: Colors.black26,
                    )
                  ],
                ),
                child: Column(
                  crossAxisAlignment: CrossAxisAlignment.start,
                  mainAxisSize: MainAxisSize.min,
                  children: [
                    
                    Padding(
                        padding: EdgeInsets.only(left: 16, top: 10),
                        child: Column(
                          mainAxisAlignment: MainAxisAlignment.start,
                          crossAxisAlignment: CrossAxisAlignment.start,
                          children: <Widget>[
                            Text(
                              keranjangProduk.nama_toko,
                              style: TextStyle(
                                  fontSize: 16,
                                  fontWeight: FontWeight.bold),
                              // textAlign: TextAlign.start,
                            ),
                          ],
                        )),
                    Padding(
                        padding: EdgeInsets.all(8),
                        child: Column(
                          crossAxisAlignment: CrossAxisAlignment.start,
                          children: keranjangProduk.produk
                              .map((e) => 
                                ListTile(
                                    title: Text(e.nama_obat),
                                    subtitle: Text(
                                      e.harga_obat.toString(),
                                    )),
                              )
                              .toList(),
                         
                        )),
                  ],
                ),
              ),
            );
          },
        );
