GridView.count 实现一行2张图的列表

 

class HomeContent extends StatelessWidget {
  const HomeContent({super.key});

  List<Widget> _getListData() {
    var tempList = listData.map((value) {
      return Container(
        child: Column(
          children: <Widget>[
            ClipRRect(
              borderRadius: BorderRadius.only(
                topLeft: Radius.circular(10.0),
                topRight: Radius.circular(10.0),
              ),
              child: Image.network(
                value["imageUrl"],
                fit: BoxFit.contain,
              ),
            ),
            // Image.network(
            //   value["imageUrl"],
            //   fit: BoxFit.contain,
            // ),
            SizedBox(height: 12),
            Text(value["title"],
                textAlign: TextAlign.left,
                style: TextStyle(
                    fontSize: 20,
                    decoration: TextDecoration.lineThrough,
                    decorationStyle: TextDecorationStyle.solid)),

                color: Color.fromRGBO(230, 230, 230, 0.9), width: 1.0),
            borderRadius: const BorderRadius.all(
              Radius.circular(15),
            )),

    });
    return tempList.toList();
  }
