Instead of using Stack you can use Transform.translate to shift the TextButton up by the half of its height:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
MyApp({super.key});
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Material App',
home: Scaffold(
appBar: AppBar(
title: const Text('Material App Bar'),
),
body: Column(
children: [
Expanded(
flex: 1,
child: Container(
alignment: Alignment.bottomCenter,
color: Color(0xFFF09384),
),
),
Expanded(
flex: 3,
child: Container(
alignment: Alignment.topCenter,
color: Color(0xFF3E8C92),
child: Column(
children: [
Transform.translate(
offset: Offset(0,-35/2), // Here you insert the half of the button height
child: TextButton(
onPressed: () => print("Hello"),
child: Text("Edit Profile"),
style: TextButton.styleFrom(
fixedSize: Size(120, 35), // Here you should fix the size of the button
backgroundColor: Colors.white,
primary: Color(0xFF3E8C92),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(20)
)
),
),
),
...List<Text>.filled(5, Text("Data"))
]
),
),
),
],
)
),
);
}
}
