How to align widgets in a GridView in Flutter? - flutter

Question

I want to align the contents of a GridView item to the center (both vertically and horizontally) without changing the size of the widget.
This code creates a GridView with an item in it, it has a default top-center alignment and the size is a default square.
GridView.count(
crossAxisCount: 3,
children: [
Container(
// alignment: Alignment.center,
child: RaisedButton(
child: Column(
children: [
Text("Top text"),
Text("Bottom text"),
],
),
onPressed: (){}
),
),
],
);
And it looks like this:
When I uncomment the alignment, it doesn't align the items correctly and the size of the item changes, I don't want neither of them.
Note that I need multiple Widgets in that GridView item, so I can't remove the Column (but maybe I can replace it?).

Answer 1

I don't see any size change after adding mainAxisAlignment to the Column. Please run the code below :
import 'package:flutter/material.dart';
final Color darkBlue = Color.fromARGB(255, 18, 32, 47);
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData.dark().copyWith(scaffoldBackgroundColor: darkBlue),
debugShowCheckedModeBanner: false,
home: Scaffold(
body: Center(
child: MyWidget(),
),
),
);
}
}
class MyWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return GridView.count(
crossAxisCount: 3,
children: [
Container(
// alignment: Alignment.center,
child: RaisedButton(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text("Top text"),
Text("Bottom text"),
],
),
onPressed: () {}),
),
],
);
}
}
