Flutter row mainAxisAlignment spaceBetween不工作
Flutter row mainAxisAlignment spaceBetween不工作

这是我用来构建项目视图容器的代码：
Widget buildItemView(InboxItem t) {
return GestureDetector(
behavior: HitTestBehavior.translucent,
onTap: () => print("ontap")),
child: Column(
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Padding(padding: EdgeInsets.fromLTRB(15.0, 10.0, 15.0, 10.0),
child: Row(
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Container(
icon ...
),
Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
/// title
_buildTitle(t),
...
],
)
],
)),
Divider(height: 3.0)
],
),
);
}和_buildTitle代码，这里是问题出现的地方：
Widget _buildTitle(InboxItem item) {
return Container(
padding: EdgeInsets.only(bottom: 2.0),
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
/// sender
Text(item.sender == null ? "" : item.sender, style: ltBlackLargeText),
/// time
Text(item.receiveTime == null ? "" : item.receiveTime,
style: dkGreySmallText),
],
),
);
}运行结果，时间紧跟在用户名之后，而不是右边。

由于上级不会填充剩余空间，因此请更改项目视图代码：
Widget buildItemView(InboxItem t) {
return GestureDetector(
behavior: HitTestBehavior.translucent,
onTap: () => print("ontap")),
child: Column(
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Padding(padding: EdgeInsets.fromLTRB(15.0, 10.0, 15.0, 10.0),
child: Row(
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Container(
icon ...
),
Expanded(
child:Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisSize: MainAxisSize.min,
children: <Widget>[
/// title
_buildTitle(t),
...
],
) ,
)
],
)),
Divider(height: 3.0)
],
),
);
