home: Scaffold(
appBar: AppBar(
title: Text(title),
),
body: GridView.builder(
itemCount: _listViewData.length,
gridDelegate:
SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 2),
itemBuilder: (context, index) {
return Card(
margin: const EdgeInsets.all(10.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
AspectRatio(
aspectRatio: 18.0 / 13.0,
child: Image.network(
_listViewDataImage[index],
fit: BoxFit.fill,
),
),
Padding(
padding: EdgeInsets.fromLTRB(16.0, 12.0, 16.0, 8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,

推荐答案
问题来自SliverGridDelegateWithFixedCrossAxisCount:
The problem comes from SliverGridDelegateWithFixedCrossAxisCount:
创建在横轴上具有固定数量的图块的网格布局
这位代表创建了大小相等的和间隔的瓷砖的网格.
Creates grid layouts with a fixed number of tiles in the cross axis
This delegate creates grids with equally sized and spaced tiles.
我建议您使用 flutter_staggered_grid_view:并放弃AspectRatio小部件. 此处.
I recommend you to use flutter_staggered_grid_view: and to give up to AspectRatio widget. More about tiles here.
body: StaggeredGridView.countBuilder(
crossAxisCount: 2,
itemCount: 6,
itemBuilder: (BuildContext context, int index) =>
Card(
margin: const EdgeInsets.all(10.0),
child: Container(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Image.network('https://upload.wikimedia.org/wikipedia/commons/6/66/An_up-close_picture_of_a_curious_male_domestic_shorthair_tabby_cat.jpg',
fit: BoxFit.fill,
),
Padding(
padding: EdgeInsets.fromLTRB(16.0, 12.0, 16.0, 8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text("Cat",textAlign: TextAlign.center),
],
),
)],
),
)
),
staggeredTileBuilder: (int index) =>
StaggeredTile.fit(1),
)
