I am trying to align the "Book Now" text and the add to cart icon to the righthand side of the screen. I have tried adding text alignment property also tried with Expanded/Column. It doesn't get aligned to the right side of the screen. Any hints to fix this? Thanks
Sample code and screenshot below tried in - https://www.dartpad.dev/flutter
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 Row(
children: <Widget>[
InkWell(
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Icon(Icons.add_shopping_cart),
Text('Book Now', textAlign: TextAlign.right),
],
),
)
],
);
}
}
You want it aligned on the right?
Use mainAxisAlignment: MainAxisAlignment.end on your first row.
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 Row(
mainAxisAlignment: MainAxisAlignment.end,
children: <Widget>[
InkWell(
child: Row(
children: <Widget>[
Icon(Icons.add_shopping_cart),
Text('Book Now', textAlign: TextAlign.right),
],
),
)
],
);
}
}
try this:
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: MyWidget(),
),
);
}
}
class MyWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Align(
alignment: Alignment.centerRight,
child: InkWell(
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Icon(Icons.add_shopping_cart),
Text('Book Now', textAlign: TextAlign.right),
],
),
),
);
}
}

I need to put a divider in a Column inside a Row but the divider does not appear. I saw some questions about the Row should not be used but in my case, I need the Row. Here is the simplest code, I need the divider to be shown
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({super.key, required this.title});
final String title;
#override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Column(
children: const [
Text('up'),
Divider(
color: Colors.black,
thickness: 2,
),
Text('bottom'),
],
),
],
),
),
);
}
}
To get the divider to show, you need to warp your Divider() with a SizedBox() and define a set width. As well as removing const form the Column() since we're using MediaQuery:
SizedBox(
width: MediaQuery.of(context).size.width,
child: Divider(
color: Colors.black,
thickness: 2,
),
),
Result:
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp();
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({required this.title});
final String title;
#override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Column(
children: [
Text('up'),
SizedBox(
width: MediaQuery.of(context).size.width,
child: Divider(
color: Colors.black,
thickness: 2,
),
),
Text('bottom'),
],
),
],
),
),
);
}
}
While the structure is
Center
- Row
- Column
- Text
- Divider
- Text
This divider doesn't get any constrained and the result is invisible on UI.
Wrapping Divider with SizedBox provide the constraints, and we are able to see the divider. Also you can go for Expanded on Column widget.
body: Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Expanded(
child: Column(
children: const [
Text('up'),
Divider(
color: Colors.green,
thickness: 2,
),
Text('bottom'),
],
),
),
],
),
),
I'm trying to make an expandable button, a bit like the expandable fab, except it's not a fab as it is not floating. This is the expandable fab for perspective:
What I'm trying to achieve though is to have a self contained button that expands above it with a menu. Self contained is in bold because I'd like the widget to be used easily without having to modify the parents structure.
So if you copy paste the code below in dartpad you'll see a yellow bar at the bottom. However if you uncomment the lines which are commented, which represents the menu expanding, you'll see that the bottom bar is pushed to the top.
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: Column(
children: [
Expanded(child: Container(color: Colors.purple)),
MyWidget(),
]
),
),
),
);
}
}
class MyWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return SizedOverflowBox(
size: Size(double.infinity, 100),
child: Stack(
children: [
Container(color: Colors.amber, height: 100),
// Transform.translate(
// offset: Offset(0, -400),
// child: Container(color: Colors.lightBlue, height: 400, width: 80),
// ),
]
)
);
}
}
So my questions are:
How do I achieve the required result where the bottom bar does not move and a menu above it (light blue container); modifying only MyWidget and not MyApp ?
Why in the current code the bar is pushed above ?
Overlay and OverlayEntry can help to achieve this:
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: Column(
children: [
Expanded(child: Container(color: Colors.purple)),
MyWidget(),
]
),
),
),
);
}
}
class MyWidget extends StatelessWidget {
OverlayEntry? _overlayEntry;
_hideMenu() {
_overlayEntry?.remove();
}
_showMenu(BuildContext context) {
final overlay = Overlay.of(context);
_overlayEntry = OverlayEntry(
builder: (ctx) => Stack(
children: [
GestureDetector(
onTap: () => _hideMenu(),
child: Container(color: Colors.grey.withAlpha(100)),
),
Positioned(
bottom: 100,
left: 50,
child: Container(color: Colors.pink, height: 200, width: 50,),
),
],
)
);
overlay?.insert(_overlayEntry!);
}
#override
Widget build(BuildContext context) {
return GestureDetector(
onTap: () => _showMenu(context),
child: Container(color: Colors.amber, height: 100)
);
}
}
Try this, run this code in dartpad.
It contains one parent, three child which can be called using the menu buttons,
The FloatingActionButton.extended used in this code can be replaced by any custom Widget, you can give onTap methods for clicks,
I have used simple widgets, Let me know wether you were looking for something like that, or something different.

);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
bool showButtons = false;
var index = 0;
List<Widget> childList = [Child1(), Child2(), Child3()];
#override
Widget build(BuildContext context) {
return Scaffold(

After calling Navigator pushReplacement, I arrive at a screen where I'd like to open a modal or a dialog automatically after the screen loads. I'm trying to do that using Timer.run inside initState() but it doesn't work, it doesn't show any errors as well. Could anyone help me understand what am I missing here?
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'dart:async';
class AfterSplash extends StatefulWidget {
#override
_AfterSplashState createState() => _AfterSplashState();
}
class _AfterSplashState extends State<AfterSplash> {
void initState() {
super.initState();
Timer.run(() {
showDialog(
context: context,
builder: (_) => AlertDialog(title: Text("Dialog title")),
);
});
}
#override
Widget build(BuildContext context) {
return opacityLogoTitle();
}
}
Widget opacityLogoTitle() {
return Scaffold(
body: Opacity(
opacity: 0.5,
child: Scaffold(
body: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Center(
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Container(

The issue is the animation can't be displayed but only image can be shown. There is only part of code about BottomAnimeLoader right here. So please help me figure what's happen why only the static image is right here. (using flutter framework and dart language)
the animation is static
import 'package:flare_flutter/flare_actor.dart';
import 'package:flutter/material.dart';
class BottomAnimeLoader extends StatefulWidget {
#override
_BottomAnimeLoaderState createState() => _BottomAnimeLoaderState();
}
class _BottomAnimeLoaderState extends State<BottomAnimeLoader> {
String _animationName = "new";
#override
Widget build(BuildContext context) {
return Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
mainAxisSize: MainAxisSize.min,
children: [
Expanded(
child: FlareActor(
"assets/flr/success.flr",
fit: BoxFit.contain,
alignment: Alignment.center,
animation: _animationName,
))
],
),
);
}
}
I use the official example's flr file to simulate this case because I do not have your flr file
If you have wrong _animationName name, then it will become static image
In official example, the _animationName is idle, if I change it to new it will become static image
Please correct your _animationName, for example the following https://rive.app/a/pollux/files/flare/success-check _animationName is Untitled
