我使用AnimatedList,但在项目中使用阴影,我的项目如下面的代码,我需要一些帮助!
class TextSentMessage extends StatelessWidget {
final String textMessage;
final Widget buildStatus;
TextSentMessage({this.textMessage, this.buildStatus});
@override
Widget build(BuildContext context) {
print('message 4 : ' + textMessage);
return Row(
mainAxisAlignment: MainAxisAlignment.end,
crossAxisAlignment: CrossAxisAlignment.end,
children: <Widget>[
Stack(
overflow: Overflow.visible,
children: <Widget>[
Container(
padding: EdgeInsets.only(
top: 10.0, bottom: 10.0, left: 20.0, right: 15.0),
margin: EdgeInsets.all(5.0),
constraints: BoxConstraints(
maxWidth: 0.7 * MediaQuery.of(context).size.width,
minWidth: 50.0),
decoration: BoxDecoration(
color: Color.fromARGB(255, 0, 117, 255),
boxShadow: [
BoxShadow(
color: black_7, blurRadius: 64, offset: Offset(0, 7))
],
borderRadius: BorderRadius.only(
topLeft: Radius.circular(20),
topRight: Radius.circular(20),
bottomRight: Radius.circular(6),
bottomLeft: Radius.circular(20)),
),
child: Text(textMessage,
textAlign: TextAlign.right,
style: TextStyle(
fontFamily: 'UTM Avo',
fontSize: 15.0,
color: Colors.white))),
],
),
buildStatus
],
);
}
}

我无法复制您的问题@quyen。
这是我在iOS模拟器和Flutter 1.5.4-hotfix.2(稳定通道)上所做的测试:
动画列表: 子代:AnimatedList( initialItemCount:msgs.length, itemBuilder: (BuildContext ctx,int索引,Animation动画){ 返回TextSentMessage( buildStatus:图标( Icons.check_circle, 大小:18, 颜色:Color.fromARGB(255,0,117,255), ), textMessage:msgs [index], ); }, ),
“列表视图”构建器:
child: ListView.builder(
itemBuilder: (ctx, index) {
return TextSentMessage(
buildStatus: Icon(
Icons.check_circle,
size: 18,
color: Colors.green,
),
textMessage: 'This is a text message!',
);
},
itemCount: 6,
scrollDirection: Axis.vertical,
),
