我正在尝试开发卡片,卡片下面带有一些文本小部件。看下面的图片。
我面临的问题是,位置图标旁边的文本较大时,它会溢出。我已经尝试过Flex,但是会引发异常。卡的右下角还有一个星形图标。
这就是我想要的:
请帮助!预先感谢。
这是我的代码:
Scaffold buildOffersList(OfferModel offerModel) {
return Scaffold(
body: Stack(
children: <Widget>[
Center(
child: Image.network(
'https://b.zmtcdn.com/data/pictures/2/19250332/0fe23bee17b60d181fd43421ca3480d4_featured_v2.jpg',
fit: BoxFit.cover,
width: size.width,
height: size.height,
color: Colors.black.withOpacity(.6),
colorBlendMode: BlendMode.darken
),
),
Column(
children: <Widget>[
Container(
child: PageHeader(pageTitle: 'Popular Offers', numberOfOffers: '20 venues', sortByText: 'Sort By: Location', filterText: 'Filter'),
),
Expanded(
child: GridView.count(
crossAxisCount: 2,
mainAxisSpacing: 5.0,
crossAxisSpacing: 5.0,
padding: const EdgeInsets.only(left: 10.0, right: 10.0),
children: List.generate(offerModel.payload.offers.length, (index) {
return Center(
child: offerCard3(offerModel.payload.offers[index]),
);
}),
),
),
],
),
],
)
);
}
Widget offerCard3(Offer offer) {
return GestureDetector(
child: Card(
elevation: 1.0,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(0.0),
),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
AspectRatio(
aspectRatio: 18.0 / 8.0,
child: Image.network(
"https://b.zmtcdn.com/data/pictures/2/19250332/0fe23bee17b60d181fd43421ca3480d4_featured_v2.jpg",
fit: BoxFit.cover,
),
),
Padding(
padding: EdgeInsets.fromLTRB(7.0, 5.0, 4.0, 5.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
getBrandName(offer),
getOfferTitle(offer),
SizedBox(height: 15.0),
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
getLocationIcon(),
getOfferContactAddressView(offer),
],
),
getKmText(),
],
),
//Spacer(),
getStarIcon(),
],
),
],
),
),
],
),
),
);
}
Text getOfferContactAddressView(Offer offer) {
return Text(
offer.offerContactAddress,
maxLines: 1,
overflow: TextOverflow.ellipsis,
style: TextStyle(
color: Colors.black38,
fontSize: 9.0,
),
);
}
Icon getStarIcon() {
return Icon(
Icons.star,
color: Colors.orange,
size: 25,
);
}
有一个flutter包,用于自动调整文本大小以包含全文。

我认为您必须使用以下代码:-
Expanded(
child: Wrap(
direction: Axis.horizontal,
runAlignment: WrapAlignment.start,
children: <Widget>[
getOfferContactAddressView(offer),
],
),
flex: 1,
),
高度推荐的第一个解决方案
首先,您可以使用Listtile。
ListTile(title: Text("ListTile"),
subtitle: Text("Sample Subtitle. \nSubtitle line 3"),
trailing: Icon(Icons.home),
leading: Icon(Icons.add_box),
isThreeLine: true,
)
第二解决方案>>
SizedBox(
width: 500,
child: new Text(
'Text largeeeeeeeeeeeeeeeeeeeeeee',
//Overflow: TextOverflow.ellipsis will make you large text end with ....
overflow: TextOverflow.ellipsis,
style: new TextStyle(
fontSize: 13.0,
),
),
),
尝试以下代码:
发生这种情况是因为Text Widget
不知道Row
的宽度有多大。
