creating flatlist grid from api data

问题

我想在FlatList中创建一个动态网格,但当数据增加时它并不是动态的,我的数据是一个包含图像和其他信息的对象数组。

我正在使用:

columnWrapperStyle={{flexWrap: 'wrap', flex: 1 / 2}}

width: "100%",
height: height / 2.3,


我想创建类似于这样的东西

如果只有一张图片,网格应该覆盖整个宽度;如果有两张图片,它应该占据一半宽度。

现在主要的问题是,当有三张图片时,第一张的高度应该是完整的,其他的将把高度分成两半,最后一张也是如此。

谢谢。

height: height / 2.3,

I want to create something like this
创建来自API数据的FlatList网格

if there is one image the grid should cover full width and if two images it should take half of width,

now the main issue I want to do something when there are three images the first height should be full and others will divide the height in half, same for the last one.

thanks.
