Flutter row mainAxisAlignment spaceBetween not working - flutter

Question

This is my code to build the item view container:
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)
],
),
);
}
and _buildTitle code, here is where the problem occurs:
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),
],
),
);
}
Run result, time is immediately after the username instead of the right.
This is part of the screenshot:
Where is the problem?

Answer 1

Because the superior does not fill the remaining space, change the item view code:
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)
],
),
);
}

Answer 2

Wrap Column Widget with Expanded inside Row as below,
Row(
children: [
Image.asset("assets/..."),
Expanded(
child: Column(children: [
Row(
children: [
Text("admin"),
Text("2020-12-14"),
],
),
]),
),
],
)

Answer 3

See this image
Wrap your row in the SizedBox widget and set your desired width. Inside the column widget, the row is not getting enough width to apply mainAxisAlignment: MAinAxisAlignment.spaceBetween.
Row(
children: [
// avatar image
const CircleAvatar(
backgroundColor: Colors.yellow,
radius: 45,
),
const SizedBox(width: 10),
// for side details
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
// for first row using spaceBetween
SizedBox(
width: MediaQuery.of(context).size.width * 0.6,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: const [
Text('admin'),
Text('20-10-2020'),
],
),
),
// other details
const SizedBox(height: 10),
const Text('123'),
const SizedBox(height: 10),
const Text('12312'),
],
),
],
),

You don't need to these three lines;
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
mainAxisSize: MainAxisSize.max,
Just use Spacer() to push the next item to the end of empty space. Here is your final code;
Widget _buildTitle(InboxItem item) {
return Container(
padding: EdgeInsets.only(bottom: 2.0),
child: Row(
children: <Widget>[
/// sender
Text(item.sender == null ? "" : item.sender, style: ltBlackLargeText),
Spacer(),
/// time
Text(item.receiveTime == null ? "" : item.receiveTime,
style: dkGreySmallText),
],
),
);
}
