您可以按照以下方式使用 gridView.builder 和行小部件进行构建。

@override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Demo"),
      ),
      body: Container(
          child: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          Text("Top"),
          Expanded(
            child: Row(
              children: [
                Expanded(
                  child: GridView.builder(
                    scrollDirection: Axis.horizontal,
                    itemCount: 10,
                    gridDelegate: new SliverGridDelegateWithFixedCrossAxisCount(
                        crossAxisCount: 2),
                    itemBuilder: (BuildContext context, int index) {
                      return Text(index.toString());
                    },
                  ),
                )
              ],
            ),
          ),
          Text("Trending"),
          Expanded(
            child: Row(
              children: [
                Expanded(
                  child: GridView.builder(
                    scrollDirection: Axis.horizontal,
                    itemCount: 10,
                    gridDelegate: new SliverGridDelegateWithFixedCrossAxisCount(
                        crossAxisCount: 2),
                    itemBuilder: (BuildContext context, int index) {
                      return Text(index.toString());
                    },
                  ),
                )
              ],
            ),
          ),
        ],
      )),
    );
  }
