已有一些画廊构建插件,你可以在 pub.dev 上查看,例如 flutter_staggered_grid_viewstaggered_grid_view_flutter

无论如何,如果你想尝试创建一个不同的画廊或自定义网格设计,可能你应该创建自己的小部件。

对于你的示例,我的方法不是网格,而是一个列表视图。
每一行都会有你的自定义布局,加载多个图像(根据你的示例最多可以加载4张照片),或根据你可能实现的其他布局设计加载更多照片。

你也可以使用两列内含两行,或者使用行和容器或SizedBox来创建这种效果。

英文:

There are already some gallery builder plugins, that you can probably check on pub.dev, like the flutter_staggered_grid_view or the staggered_grid_view_flutter

Anyway, if you want to try to create a different gallery or a custom grid design, probably you should create your own widget.

For your example, my approach would not be a grid but a List View.
Each row would have your custom layout, loading multiple images, (up to 4 photos according to your example), or more depending on other layout designs you might implement.

you can also create this effect using 2 Columns with 2 rows inside or
with rows and containers or SizedBox.

你可以使用 flutter_staggered_grid_view,你需要调整 mainAxisCellCount。当有4个项目在一组时,它将是

mainAxisCellCount: switch (i % 4) {
  0 || 3 => .25,
  _ => .75,
},

你可以使用这个小部件。

class Stg4 extends StatelessWidget {
  const Stg4({super.key});

  @override
  Widget build(BuildContext context) {
    final items = List.generate(10, (index) => "path $index");
    List<Widget> children = [
      for (int i = 0; i < items.length; i++)
        StaggeredGridTile.count(
          crossAxisCellCount: 1,
          mainAxisCellCount: switch (i % 4) {
            0 || 3 => .25,
            _ => .75,
          },
          child: ColoredBox(color: Colors.cyanAccent, child: Text(items[i])),
        ),
    ];
    return Scaffold(
      body: StaggeredGrid.count(
        crossAxisCount: 2,
        mainAxisSpacing: 4,
        crossAxisSpacing: 4,
        children: children,
      ),
    );
  }
}
英文:

You can use flutter_staggered_grid_view, you need to play with mainAxisCellCount. While 4 items are in a group, it will be

mainAxisCellCount: switch (i % 4) {
  0 || 3 =&gt; .25,
  _ =&gt; .75,
},

You can play with this widget.

class Stg4 extends StatelessWidget {
  const Stg4({super.key});

  @override
  Widget build(BuildContext context) {
    final items = List.generate(10, (index) =&gt; &quot;path $index&quot;);
    List&lt;Widget&gt; children = [
      for (int i = 0; i &lt; items.length; i++)
        StaggeredGridTile.count(
          crossAxisCellCount: 1,
          mainAxisCellCount: switch (i % 4) {
            0 || 3 =&gt; .25,
            _ =&gt; .75,
          },
          child: ColoredBox(color: Colors.cyanAccent, child: Text(items[i])),
        ),
    ];
    return Scaffold(
      body: StaggeredGrid.count(
        crossAxisCount: 2,
        mainAxisSpacing: 4,
        crossAxisSpacing: 4,
        children: children,
      ),
    );
  }
}
