Improve this question
I'm new to flutter but I have a curiosity. Considering the typical bootstrap admin UI that you can find online and the typical left menu, how would you recreate that with flutter? I'm particularly interested on a left menu that can be resized clicking on a button and on a sub-menu that can appear and disappear.
An example can be found here
Edit:
I want to be be clear about the effect I'm trying to reproduce as well. If you click the link relative to the example on the left you see a number of menu. For instance, clicking on Base you are going to see a vertical menu appearing and disappearing. I would like to know how to reproduce it as well.
Thanks
Thanks

I have tried to re-create the same design with some minor changes in Flutter. I have to enable flutter web support by following the instructions here:
Flutter Web
Regarding the left menu, I have used AnimatedSize widget to give the sliding drawer feel & placed it inside Row.
Please find the code below:
import 'package:flutter/material.dart';
final Color darkBlue = Color.fromARGB(255, 18, 32, 47);
void main() {
runApp(MyApp());

class MyWidget extends StatefulWidget {

_MyWidgetState createState() => _MyWidgetState();
}
class _MyWidgetState extends State<MyWidget>
with SingleTickerProviderStateMixin {
final colors = <Color>[Colors.indigo, Colors.blue, Colors.orange, Colors.red];
double _size = 250.0;
bool _large = true;
void _updateSize() {
setState(() {
_size = _large ? 250.0 : 0.0;
_large = !_large;
});
}
#override
Widget build(BuildContext context) {
return Scaffold(

You can use the Drawer widget inside a Scaffold. If you want the navigation drawer to be able to resize according to the browser height and width you can use the responsive_scaffold package.

Flutter how to add a dialog screen over main screen like this

Hi all,
I would like to add a screen that slowly appears form the bottom or the screen and partially covers the main screen below. So you can still see the top part of the main screen. Does anyone know how to do this?
Thank you very much
for this you can use showModalBottomSheet method the simple example is
import 'package:flutter/material.dart';
void main() => runApp(const BottomSheetApp());
class BottomSheetApp extends StatelessWidget {
const BottomSheetApp({super.key});
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(title: const Text('Bottom Sheet Sample')),
body: const BottomSheetExample(),
),
);
}
}
class BottomSheetExample extends StatelessWidget {
const BottomSheetExample({super.key});
#override
Widget build(BuildContext context) {
return Center(
child: ElevatedButton(
child: const Text('showModalBottomSheet'),
onPressed: () {
showModalBottomSheet<void>(
context: context,
builder: (BuildContext context) {
return Container(
height: 200,
color: Colors.amber,
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
mainAxisSize: MainAxisSize.min,
children: <Widget>[
const Text('Modal BottomSheet'),
ElevatedButton(
child: const Text('Close BottomSheet'),
onPressed: () => Navigator.pop(context),
),
],
),
),
);
},
);
},
),
);
}
}
you can read more about this method here
You can use showModalBottomSheet() same as below...
showModalBottomSheet<void>(
// context and builder are
// required properties in this widget
context: context,
builder: (BuildContext context) {
// we set up a container inside which
// we create center column and display text
// Returning SizedBox instead of a Container
return SizedBox(
height: MediaQuery.of(context).size.height * 0.6,
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: const <Widget>[
Text('HERE You'll add all your content'),
],
),
),
);
},
);
You can call above method in
initState() of screen or buttons onPressed or onTap.
As per your shared Image I have try something like that Using ModalBottomSheet
Your Button Widget
ElevatedButton(
child: const Text('Show Modal BottomSheet'),
onPressed: () {
showModalBottomSheet<void>(
shape: const RoundedRectangleBorder(
borderRadius: BorderRadius.vertical(top: Radius.circular(25.0)),
),
context: context,
builder: (BuildContext context) {
return modelSheet(context);
},
);
},
)
bottomSheet Widget:
modelSheet(BuildContext context) {
return Container(
padding: const EdgeInsets.all(12),
decoration: const BoxDecoration(
borderRadius: BorderRadius.vertical(top: Radius.circular(25.0)),
),
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
const Icon(
Icons.hourglass_empty_outlined,
color: Colors.red,
size: 40,
),
const SizedBox(
height: 10,
),
const Text(
'Beta version',
style: TextStyle(
fontSize: 30,
fontWeight: FontWeight.bold,
),
),
const SizedBox(
height: 20,
),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: const [
Icon(
Icons.check,
color: Colors.red,
),
Text('better price')
],
),
const SizedBox(
height: 10,
),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: const [
Icon(
Icons.check,
color: Colors.red,
),
Text('early access')
],
),
const SizedBox(
height: 20,
),
RichText(
text: const TextSpan(
text:

how to display drop down next to he elevated button

this is two search and dropdown sections I have implemented using animated_custom_dropdown.
I want that "Get Quote Filter " button to place next to the(right side) set location drop down..................................................................................................................................
........................................................................................................................................
import 'package:animated_custom_dropdown/custom_dropdown.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import '../constants/colors.dart';
const _labelStyle = TextStyle(fontWeight: FontWeight.w600);
class FantomSearch extends StatefulWidget {
const FantomSearch({Key? key}) : super(key: key);
#override

}
}
From your code, I believe that currently "Get quotes filter" showing below to the "Set Location" correct?
If this is the issue, you need to update Column widget to Row which is inside Padding.
Like,
Container(
height: 200,
child: SingleChildScrollView(
child: Column(
children: [
/**/
Row(
children: [
Expanded(
child: CustomDropdown.search(
hintText: 'Search Services',
items: list,
controller: jobRoleSearchDropdownCtrl,
fillColor: DarkGreen,
),
),
Padding(
padding: EdgeInsets.only(left: 15, top: 20, right: 15, bottom: 20),
child: Text(
"cancel"
),
)
],
),
const SizedBox(height: 24),
// using form for validation
Padding(
padding: const EdgeInsets.only(right: 70),
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
/**/
Expanded(
child: CustomDropdown(
hintText: 'Set Location',
items: list,
controller: jobRoleFormDropdownCtrl,
excludeSelected: false,
fillColor: DarkGreen,
),
),
const SizedBox(width: 16),
SizedBox(
child: ElevatedButton(
onPressed: () {
if (!formKey.currentState!.validate()) {
return;
}
},
child: const Text(
'Get Quotes filter',
style: TextStyle(fontWeight: FontWeight.w600),
),
style: ElevatedButton.styleFrom(primary: Colors.green),
),
),
],
),
),
],
),
),
)
If this still not worked, please share the expected output and what you are getting now. Because I am not able to compile your code due to custom widgets.
I have updated the color so please update it as per your need. The output is something like,

What do I need to do to link to another file with my button widgets?

I am still learning to code. How do I store all my button widgets in another file and import it into my main file? Here is the code:
class _testState extends State<test> {
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.blue[900],
appBar: AppBar(
title: Text('test'),
backgroundColor: Colors.red[900],
),
body: GridView(
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 3,
),
children: [
//buttons
],
),
);
}
}
How can I take the code below and put it in another file and then link it to the file above by the buttons comment?
Padding(
padding: const EdgeInsets.fromLTRB(0.0, 9.0, 0.0, 0.0),
child: TextButton.icon(
onPressed: () => {},
icon: Column(
children: [
Icon(
Icons.add,
color: Colors.white,
size: 75,
),
Padding(
padding: const EdgeInsets.all(10.0),
child: Text(
'Label',
style: TextStyle(

label: Text(

-First, create a new file, name it jeff.dart.
-Second, type this in the new file: stless . Press Enter, Flutter will automatically make a new StatelessWidget for you. Change the class name to JeffButton. Now, it look like this :
class JeffButton extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Container(
);
}
}
Copy and paste the button's code , replace the Container() .Congratulations! You had the JeffButton! Now you can use it everywhere:
class JeffButton extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Padding(
padding: const EdgeInsets.fromLTRB(0.0, 9.0, 0.0, 0.0),
child: TextButton.icon(
onPressed: () => {},
icon: Column(
children: [
Icon(
Icons.add,
color: Colors.white,
size: 75,
),
Padding(
padding: const EdgeInsets.all(10.0),
child: Text(
'Label',
style: TextStyle(
color: Colors.white,
),
),
),
],
),
label: Text(
'', //'Label',
style: TextStyle(
color: Colors.white,
),
),
),
);
}
}
Now just add it to where you need it ;) :
children: [
//buttons
JeffButton(),
],
Remember to import the jeff.dart file to where you use it, you can do it easily by move the cursor to JeffButton(), show quick fixes, choose Import: .... (which is the first options). This is how to show quick fixes if you didn't know: https://flutter.dev/docs/development/tools/flutter-fix

How to go to a specific page using the button? Flutter

First you need to set up the route:
MaterialApp(
// Start the app with the "/" named route. In this case, the app starts
// on the FirstScreen widget.
initialRoute: '/',
routes: {
// When navigating to the "/" route, build the FirstScreen widget.
'/': (context) => FirstScreen(), //NOTE: Change the FirstScreen() to your own screen's class name (ex: WelcomeScreen())
// When navigating to the "/second" route, build the SecondScreen widget.
'/second': (context) => SecondScreen(), //NOTE: Change the SecondScreen() to your own screen's class name (ex: HomeWidget())
'/third': (context) => ThirdScreen(),
},
);
And then, inside your button, navigate to the page:
// Within the `FirstScreen` widget
onPressed: () {
// Navigate to the second screen using a named route.
Navigator.pushNamed(context, '/second');
}

Flutter: is there any possibility to send the button value to the text field?

I am Writing a small quiz game, in which I am pressing the button and these buttons are going to the empty text fields, I don't know how to send the text of the button to the text fields.
here is my code :
import 'package:flutter/material.dart';
void main() => runApp(MaterialApp(home: NinjaCard()));
class NinjaCard extends StatefulWidget {
#override
_NinjaCardState createState() => _NinjaCardState();
}
class _NinjaCardState extends State<NinjaCard> {
String result = "";
String shaka = "";
var text;
String str;
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
appBar: AppBar(title: Text('Animals'), backgroundColor: Colors.green),
body: Padding(
padding: EdgeInsets.all(15),
child: Column(
children: <Widget>[
Center(
child: Image.asset('lib/photo-1495594059084-33752639b9c3.jpg'),
),
SizedBox(width: 10, height: 10),
Row(children: <Widget>[
Container(
color: Colors.grey,
width: 40.0,
child: Text('$result', style: TextStyle(fontSize: 10.0, height: 2.0, color: Colors.black)),
),
SizedBox(width: 10),
Container(
color: Colors.grey,
width: 40.0,
child: Text('$shaka', style: TextStyle(fontSize: 10.0, height: 2.0, color: Colors.black)),
),
SizedBox(width: 15),
Row(
children: <Widget>[
SizedBox(
width: 50,
child: RaisedButton(
onPressed: () {},
color: Colors.green,
splashColor: Colors.red,
child: Text('S', style: TextStyle(backgroundColor: Colors.green, fontSize: 20, color: Colors.white)),
),
),
SizedBox(width: 15),
SizedBox(
width: 50,
child: RaisedButton(
onPressed: () {},
color: Colors.green,
splashColor: Colors.red,
child: Text('T', style: TextStyle(backgroundColor: Colors.green, fontSize: 20, color: Colors.white)),
),
),
SizedBox(width: 15),
],
),
]),
],
),
),
);
}
}
In a simple case, I would go with a stateful widget and array of letters. Of course, it could be created and sized dynamically, below I only explain the basic idea with some simplifications (no duplicate checks, no shuffling):
import 'package:flutter/material.dart';
void main() => runApp(App());
class App extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'App',
home: GuessTheWordWidget(),
);
}
}
class GuessTheWordWidget extends StatefulWidget {
#override
_GuessTheWordWidgetState createState() => _GuessTheWordWidgetState();
}
class _GuessTheWordWidgetState extends State<GuessTheWordWidget> {
String _word = 'Goldfish';
List<String> _input = List.generate(8, (_) => '');
int _position = 0;
void _press(int rune) {
setState(() {
if (_position < _input.length) {
print('Position ${_position}, rune: ${String.fromCharCode(rune)}');
_input[_position++] = String.fromCharCode(rune);
}
});
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('App'),
),
body: Center(
child: Column(children: <Widget>[
Expanded(
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: _input
.map((letter) => Container(
margin: const EdgeInsets.all(15.0),
padding: const EdgeInsets.all(3.0),
decoration: BoxDecoration(
border: Border.all(color: Colors.blueAccent)),
child: Text(letter),
))
.toList())),
Expanded(
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: _word.runes
.map((rune) => RaisedButton(
onPressed: () => _press(rune),
child: Text(String.fromCharCode(rune),
style: TextStyle(fontSize: 20)),
))
.toList())),
])),
);
}
}
