How to remove default padding in OutlinedButton? - flutter

Question

I want to remove the default padding from an outlined button. This is my code;
SizedBox(
width: 150.0,
child: OutlinedButton(
onPressed: () {
setState(() {
selected = index;
});
},
style: OutlinedButton.styleFrom(
backgroundColor: (selected == index) ? color : Colors.white,
shape: const RoundedRectangleBorder(
borderRadius: BorderRadius.only(
topLeft: Radius.circular(20),
topRight: Radius.circular(30),
bottomLeft: Radius.circular(20),
bottomRight: Radius.circular(20),
),
),
),
child: Row(
children: [
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(duration),
Text(dataPlan),
Text(price),
],
),
],
),
),
);
The SizedBox is wrapped in a ListView.
This is the result I get;
I want the paddings at the left and right removed, so I can customize to my preference. Thanks.

Answer 1

Just add minimumSize: Size.zero,padding: EdgeInsets.zero, in OutlinedButton.styleFrom()
SizedBox(
width: 150.0,
height:100,
child: OutlinedButton(
onPressed: () {
},
style: OutlinedButton.styleFrom(
minimumSize: Size.zero,
padding: EdgeInsets.zero,
backgroundColor: Colors.yellow,
shape: const RoundedRectangleBorder(
borderRadius: BorderRadius.only(
topLeft: Radius.circular(20),
topRight: Radius.circular(30),
bottomLeft: Radius.circular(20),
bottomRight: Radius.circular(20),
),
),
),
child: Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Column(
children: [
Text("duration"),
Text("dataPlan"),
Text("price"),
],
),
],
),
)),

Answer 2

Add in Column this property to reduce size of the widget.
Column(
mainAxisSize: MainAxisSize.min
...

Answer 3

Add the following properties to the button style:
tapTargetSize: MaterialTapTargetSize.shrinkWrap
minimumSize: Size.zero
padding: EdgeInsets.zero
In addition, set the mainAxisSize on the Column and on the row to min:
child: Row(
mainAxisSize: MainAxisSize.min,
children: [
Column(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(duration),
Text(dataPlan),
Text(price),
],
),
],
),
