Widget, ScrollChildView

.Anyone know or have any idea about this?
import "package:flutter/material.dart";
import 'package:audioplayers/audio_cache.dart';
class Account extends StatefulWidget {
Account({Key key}) : super(key: key);
@override
_AccountState createState() => _AccountState();
}
class _AccountState extends State<Account> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: SingleChildScrollView(
child: Stack(
children: [
Container(
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
TextButton(
child: Container(
child: Text(
'One',
style: TextStyle(color: Colors.white, fontSize: 10),
),
),
style: ButtonStyle(
backgroundColor:
MaterialStateProperty.all<Color>(Colors.red),
),
onPressed: () {
final player = AudioCache();
player.play('note1.wav');
},
),
SizedBox(
height: 1,
),
TextButton(
child: Container(
child: Text(
'Two',
style: TextStyle(color: Colors.white, fontSize: 10),
),
),
style: ButtonStyle(
backgroundColor:
MaterialStateProperty.all<Color>(Colors.green),
),
onPressed: () {
final player = AudioCache();
player.play('note2.wav');
},
),
TextButton(
child: Container(
child: Text(
'Three',
style: TextStyle(color: Colors.white, fontSize: 10),
),
),
style: ButtonStyle(

You just wrap your text button with the SizedBox
and set height and width as follows:
SizedBox(
height: 30,
width: 150,
child: TextButton(...),
)
Full available height:
SizedBox( height: double.infinity, // <-- match_parent child: TextButton(...) )
Specific height:
SizedBox( height: 100, // <-- Your height child: TextButton(...) )
In Flutter 2.0, you can set the height of the TextButton
directly without depending on other widgets by changing the ButtonStyle.fizedSize
:
TextButton(
child: Text('Text Button'),
style: TextButton.styleFrom(fixedSize: Size.fromHeight(150)),
),
If you want to modify all TextButton
s, put it in the ThemeData
like below:
return MaterialApp(
theme: ThemeData(
textButtonTheme: TextButtonThemeData(
style: TextButton.styleFrom(fixedSize: Size.fromHeight(150)),
),
),
use the following to even add your preferred size as well
N/B: child sized box is the main child widget inside Padding widget
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding: const EdgeInsets.all(30.0),
child: SizedBox(
height: 60,
width: 200,
child: ElevatedButton.icon(
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => RegistrationMenu()));
},
style: ButtonStyle(
backgroundColor:
MaterialStateProperty.all(Colors.red.shade800),
),
icon: Icon(Icons.person_add_alt_1_rounded, size: 18),
label: Text("Register Users"),
),
),
),
],
),
Wrap the TextButton in an "Expanded" Widget.
Expanded(
child: TextButton(
style: TextButton.styleFrom(
backgroundColor: Colors.red,
padding: EdgeInsets.zero,
),
child: const Text(''),
onPressed: () {
playSound(1);
},
),
),
Another solution would be wrapping with ConstrainedBox
and using minWidth
& minHeight
properties.
ConstrainedBox(
constraints:BoxConstraints(
minHeight:80,
minWidth:200
),
child:TextButton(..)
)
it's simple
TextButton(
style: ButtonStyle(
fixedSize: MaterialStateProperty.all<Size>(
// width : double.maxFinite
// height: 56.0
const Size(double.maxFinite, 56.0),
),
// fill color
backgroundColor: MaterialStateProperty.all<Color>(
Theme.of(context).primaryColorDark,
),
),
onPressed: (){
// todo: action
},
child: Text(
'button name',
),
);
TextButton(
onPressed: _submitOrder,
child: Padding(
padding: EdgeInsets.only(left: 20, right: 20),
child: Text("Raise")),
style: ButtonStyle(
shape: MaterialStateProperty.all(
const RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(50)),
side: BorderSide(color: Colors.green)))),
)
TextButton(
style: ButtonStyle(
tapTargetSize: MaterialTapTargetSize.shrinkWrap
),
child: Text(''),
);
