Modal with centered title and right aligned close/X button - flutter

Question

I recently picked up Flutter and Dart and am attempting to create an app that has a modal with three parts: a header, actual content, and a footer.
For the header I am looking to add a title (Text) center aligned and a close button right aligned.
I have the following code:
Column(
children: [
Row(
children: [
Expanded(
child: Text(
"Filters",
style: const TextStyle(
fontSize: 25,
fontWeight: FontWeight.bold,
),
textAlign: TextAlign.center,
),
),
IconButton(
icon: const Icon(Icons.close),
onPressed: () {
Navigator.pop(context);
},
),
],
),
],
),
)
Visually, this looks like so:
At a glance this looks fine but if you stare at it for a bit it doesn't. The "Filters" title isn't actually centered because (I assume) of the width of the X-button. I am struggling to figure out how to deal with this.
What is the proper way to solve this?

Answer 1

You can add empty SizedBox with width as much as IconButton takes, try this:
Row(
children: [
SizedBox(
width: width: 24 +
8 +
8, // the default size of icon + two default horizontal padding for IconButton
),
Expanded(
child: Text(
"Filters",
style: const TextStyle(
fontSize: 25,
fontWeight: FontWeight.bold,
),
textAlign: TextAlign.center,
),
),
IconButton(
icon: const Icon(Icons.close),
onPressed: () {
Navigator.pop(context);
},
),
],
),
or you can add on other IconButton with opacity 0 to hide the button and make title center, like this:
Row(
children: [
Opacity(
opacity: 0,
child: IconButton(
icon: const Icon(Icons.close),
onPressed: () {},
),
),
Expanded(
child: Text(
"Filters",
style: const TextStyle(
fontSize: 25,
fontWeight: FontWeight.bold,
),
textAlign: TextAlign.center,
),
),
IconButton(
icon: const Icon(Icons.close),
onPressed: () {
Navigator.pop(context);
},
),
],
),
