I have a Column: child: Column( children: [ Container( height: 200, width: 300, color: Colors.red, ), Align( alignment: Alignment.bottomCenter, child: Text("This Product is Built By Imtiaz")), ], ),
I want to Expand Column to print Text At Bottom Of Screen
You could put a Spacer() between your Text widget and your Container widget
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
body: Center(
child: Column(
children: [
Container(
height: 200,
width: 300,
color: Colors.red,
),
Spacer(),
Text("This Product is Built By Imtiaz"),
],
),
),
),
);
}
}

In the following code, by uncommenting // return child; the Alignment works, but when wrapping child with Column we loose the Alignment
Why? and how to fix it?
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) {
final child = Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Align(
alignment: Alignment.topLeft,
child: Container(width: 100, height: 100, color: Colors.blue),
),
Container(width: 100, height: 500, color: Colors.red),
Align(
alignment: Alignment.center,
child: Container(width: 100, height: 300, color: Colors.green),
),
Align(
alignment: Alignment.bottomCenter,
child: Container(width: 100, height: 200, color: Colors.yellow),
),
Container(width: 100, height: 100, color: Colors.purple),
],
);
// return child;
return Column(
children: [
child,
],
);
}
}
The code below will solve your problem. I just wrapped the 'child' widget with 'Expanded'.
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) {
final child = Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Align(
alignment: Alignment.topLeft,
child: Container(width: 100, height: 100, color: Colors.blue),
),
Container(width: 100, height: 500, color: Colors.red),
Align(
alignment: Alignment.center,
child: Container(width: 100, height: 300, color: Colors.green),
),
Align(
alignment: Alignment.bottomCenter,
child: Container(width: 100, height: 200, color: Colors.yellow),
),
Container(width: 100, height: 100, color: Colors.purple),
],
);
// return child;
return Column(
children: [
Expanded(child: child,),
],
);
}
}
I'm trying to center both texts, and for the T text to take as much height as possible from the parent so the only space remaining will be the container's paddings.
The code:
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
void main() {
runApp(TestApp());
}
class TestApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
// Remove status bar
SystemChrome.setEnabledSystemUIOverlays([]);
return MaterialApp(
home: Scaffold(
body: _body(),
),
);
}
Widget _body() => Container(
width: 200,
height: 200,
padding: EdgeInsets.all(16),
color: Colors.lightBlueAccent,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Expanded(
child: Container(
color: Colors.lightGreen,
child: FittedBox(
fit: BoxFit.contain,
child: Text("T"),
),
),
),
Flexible(
child: Text("subtitle"),
)
],
),
);
}
As you can see in the screenshot there are undesired paddings in the T text:
I want to add a scroll bar within a fixed size container in Flutter web as shown in the picture link below. Can anyone give me advice on this? I am stuck here. I have tried Single child scroll view with Flutter_web_scrollbar but it doesn't work. Here is the code.
Container(
width: 300,
child: SingleChildScrollView(
scrollDirection: Axis.vertical,
controller: _bcontroller,
child: Column(
children: [
Container(
width: 300,
child: Row(
children: [
Text(
'${eventList.length > 0 ? i['ShipName'] : ''}',
),
],
),
),
Container(
width: 300,
child: Row(
children: [
Text(
'${eventList.length > 0 ? i[getEventDesc()].toString() : ''}',
),
],
),
),
SizedBox(
height: 10,
),
],
),
),
)
Example
Wrap SingleChildScrollView with Scrollbar Widget.
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 Container(
width: 300,
height: 200,
child: Scrollbar(
child: SingleChildScrollView(
scrollDirection: Axis.vertical,
child: Column(
children: [
Container(
width: 300,
height: 100,
child: Row(
children: [
Text(
'your variable',
),
],
),
),
Container(
width: 300,
height: 100,
child: Row(
children: [
Text(
'your variable',
),
],
),
),
SizedBox(
height: 10,
),
],
),),
),
);
}
}
I have one problem.
My app is
SingleChildScrollView -> column -> children: A,B(variable height),C
I expcted
If A,B,C not overflow.
C position is bottom of screen.
If A,B,C overflow.
C position is tail of content.
but it's not work.
I can't use flexible, spacer..etc.. because SingleChildScrollView
How can do that?
as an option
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: SafeArea(child: SomeWidget()),
),
);
}
}
class SomeWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return CustomScrollView(
slivers: <Widget>[
SliverToBoxAdapter(
child: Container(
height: 340,
color: Colors.red[200],
),
),
SliverToBoxAdapter(
child: Container(
height: 620,
color: Colors.orange[200],
),
),
SliverFillRemaining(
hasScrollBody: false,
child: Align(
alignment: Alignment.bottomCenter,
child: Container(
height: 80,
color: Colors.green[200],
),
),
),
],
);
}
}
Hi guys i'm try to make this on flutter: img
i'm try with that code, but work
Container(
child: Positioned(top:0, left:0)
)```
as an option you can use Stack as container for card widget + image
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: Stack(
children: <Widget>[
Card(
color: Colors.blueAccent,
child: Container(
width: 300,
height: 80,
),
),
FractionalTranslation(
translation: Offset(0, -0.5),
child: Icon(Icons.android, size: 48),
),
],
),
),
),
);
}
}
