Display Text on right side of AppBarComponent - flutter

Question

So I have this AppBarComponent that displays the appbar of my app.
class AppBarComponent {
static Widget titleWithImage(String title) {
return Row(
children: <Widget>[
Image.asset(
'logo.png',
fit: BoxFit.contain,
width: 40,
),
Padding(
padding: const EdgeInsets.symmetric(horizontal: 10.0),
child: Text('title'),
),
Row(
children: [
Text(
'subtitle',
),
],
),
],
);
}
}
The result is something like this:
But what I want is to display the subtitle on the right side of the appbar.

Answer 1

Oh! I have resolved it using
Expanded(
child: Text(
'subtitle',
textAlign: TextAlign.end,
),
),
instead of wrapping it with Row.

appBar: AppBar(
leading: Padding(
padding: const EdgeInsets.all(8.0),
child: Image.network(
"https://www.clipartmax.com/png/middle/200-2009207_francais-english-italiano-english-flag-icon-flat.png",
fit: BoxFit.cover,
width: 30.0,
height: 30.0,
),
),
title: Row(children: [
Padding(
padding: const EdgeInsets.symmetric(horizontal: 10.0),
child: Text('title'),
),
Row(
children: [
Text(
'subtitle',
),
],
),
]),
flexibleSpace: Container(
decoration: const BoxDecoration(
gradient: LinearGradient(
begin: Alignment.centerLeft,
end: Alignment.centerRight,
colors: <Color>[Colors.black, Colors.blue,Colors.black,]),
),
),
),

It's not recommended to use Widget function instead use Stateful/Stateless widgets, so you can achieve it like that...
class AppBarComponent extends StatelessWidget {
const AppBarComponent({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return AppBar(
leading: const Icon(Icons.circle), //TODO replace with your logo
title: const Text('Title'),
actions: const <Widget>[
Text('Subtitle'),
],
);
}
}
