How to align expanded widgets in a row - flutter

Question

Why does the 1st two work but not the 3rd?? what's the alternative to add vertical divider with height that stretch to the max height of the row?
These 2 works
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
// crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
Container(
child: Text('Kicukiro'),
),
Container(width: 1,color: Colors.black,height: double.infinity,),
Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
)
],
)
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: Text('Kicukiro'),
),
),
// Container(width: 1,color: Colors.black,height: double.infinity,),
Expanded(
child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
),
)
],
)
this does not work
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: Text('Kicukiro'),
),
),
Container(width: 1,color: Colors.black,height: double.infinity,),
Expanded(
child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
),
)
],
)

Answer 1

Test this and it will work
IntrinsicHeight(
child: Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: const Text("Kicukiro", style: TextStyle(fontSize: 52),)),
),
Container(color:Colors.black, width: 1),
Expanded(
child: Container(
padding: const EdgeInsets.symmetric(horizontal: 10),
child: const Text("Kicukiro", style: TextStyle(fontSize: 52),)),
),
],
),
),

Answer 2

In the last screenshot please add the Container under an Expanded widget. Use children property under Row widget.
Here is an example code
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Expanded(
flex: 5,
child: Padding(
padding: EdgeInsets.all(10.0),
child: Center(
child: Text(
'This is question',
style: TextStyle(
fontSize: 25.0,
color: Colors.white,
),
),
),
),
),
Expanded(
child: Padding(
padding: EdgeInsets.all(10.0),
child: FlatButton(
//textColor: Colors.white,
color: Colors.green,
child: Text(
'True',
style: TextStyle(color: Colors.white, fontSize: 20.0),
),
onPressed: () {},
),
)),
Expanded(
child: Padding(
padding: EdgeInsets.all(10.0),
child: FlatButton(
//textColor: Colors.white,
color: Colors.red,
child: Text(
'False',
style: TextStyle(color: Colors.white, fontSize: 20.0),
),
onPressed: () {},
),
)),
]

Answer 3

The third is true, in fact, its existence in an SingleChildScrollView has created a problem
It is fixed by putting SizedBox in Row and giving it height
The reason for this problem is the size of the height of the container, which is determined by double.infinity and due to its presence in an SingleChildScrollView, it continues indefinitely and an error was created.
SingleChildScrollView(
child: SizedBox(
height: 250,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(child: Container(child: Text("Kicukiro"))),
Container(
width: 1,color: Colors.black,height: double.infinity,
),
Expanded(child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text("Kicukiro"))),
],
),
),
),
