How to get titled container in flutter - flutter

I want the container to have title over it like in this picture -
I am using stack and positioned to get the same, but instead I am getting this -
Here is my code -
Expanded(
child: Stack(
children: [
Container(
........... //Some Code
),
Positioned(
left: 0,
top: 0,
child: Text("One"),
),
],0
)
),
If I try to position it with top: -5 or -10, this is what I get -
Is there any widget for this? If no, then I think padding is the only option left with me. What should I do?

There is a package flutter_titled_container 1.0.7.
import 'package:flutter/material.dart';
import 'package:flutter_titled_container/flutter_titled_container.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
appBar: AppBar(
centerTitle: true,
title: Text('Titled Container'),
),
body: Center(
child: TitledContainer(
titleColor: Colors.blue,
title: 'Container Title',
textAlign: TextAlignTitledContainer.Center,
fontSize: 16.0,
backgroundColor: Colors.white,
child: Container(
width: 250.0,
height: 200.0,
decoration: BoxDecoration(
border: Border.all(
color: Colors.blue,
),
borderRadius: BorderRadius.all(
Radius.circular(10.0),
),
),
child: Center(
child: Text(
'Some text',
style: TextStyle(fontSize: 28.0),
),
),
),
),
),
);
}
}
More details on here.

Try below code hope its help to you.
InputDecorator(
decoration: const InputDecoration(
border: OutlineInputBorder(),
labelText: 'Academic Year',
),
child: DropdownButtonHideUnderline(
child: DropdownButton<String>(
value: dropdownValue,
isDense: true,
isExpanded: true,
onChanged: (String? newValue) {
setState(() {
dropdownValue = newValue!;
});
},
items: <String>['2021-2022', '2022-2023', '2023-2024', '2024-2025']
.map<DropdownMenuItem<String>>((String value) {
return DropdownMenuItem<String>(
value: value,
child: Text(value),
);
}).toList(),
),
),
),
Result screen->
full example:
import 'package:flutter/material.dart';
void main() => runApp(const MyApp());
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
static const String _title = 'Flutter Code Sample';
#override
Widget build(BuildContext context) {
return MaterialApp(
title: _title,
home: Scaffold(
appBar: AppBar(title: const Text(_title)),
body: const Center(
child: MyStatefulWidget(),
),
),
);
}
}
class MyStatefulWidget extends StatefulWidget {
const MyStatefulWidget({Key? key}) : super(key: key);
#override
State<MyStatefulWidget> createState() => _MyStatefulWidgetState();
}
class _MyStatefulWidgetState extends State<MyStatefulWidget> {
String dropdownValue = '2021-2022';
#override
Widget build(BuildContext context) {
return Container(
padding: EdgeInsets.all(10),
child: InputDecorator(
decoration: const InputDecoration(
border: OutlineInputBorder(),
labelText: 'Academic Year',
),
child: DropdownButtonHideUnderline(
child: DropdownButton<String>(
value: dropdownValue,
isDense: true,
isExpanded: true,
onChanged: (String? newValue) {
setState(() {
dropdownValue = newValue!;
});
},
items: <String>['2021-2022', '2022-2023', '2023-2024', '2024-2025']
.map<DropdownMenuItem<String>>((String value) {
return DropdownMenuItem<String>(
value: value,
child: Text(value),
);
}).toList(),
),
),
),
);
}
}

You can use InputDecorator
example:
InputDecorator(
child: Text("TEST"),
decoration: InputDecoration(
labelText: "lalala",
),
)
result:

Try to add margin.top to container insteads of negative Positioned.top. With the title, using Positioned.top/left/right to determine size and Align to align it to topleft, using Container with color.white to remove border line.
import 'package:flutter/material.dart';
const Color darkBlue = Color.fromARGB(255, 18, 32, 47);
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(),
body: Column(
children: [
TitledContainer(
titleText: 'Hello world!',
child: Text('Your content place here! Bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla'),
),
],
),
),
);
}
}
class TitledContainer extends StatelessWidget {
const TitledContainer({required this.titleText, required this.child, this.idden = 8, Key? key}) : super(key: key);
final String titleText;
final double idden;
final Widget child;
#override
Widget build(BuildContext context) {
return Stack(
children: [
Container(
margin: const EdgeInsets.only(top: 8),
padding: EdgeInsets.all(idden),
decoration: BoxDecoration(
border: Border.all(),
borderRadius: BorderRadius.circular(idden * 0.6),
),
child: child,
),
Positioned(
left: 10,
right: 10,
top: 0,
child: Align(
alignment: Alignment.topLeft,
child: Container(
color: Colors.white,
child: Text(titleText, overflow: TextOverflow.ellipsis),
),
),
),
],
);
}
}

Try set margin for Container
Expanded(
child: Stack(
children: [
Container(
margin: EdgeInsets.all(5), //add this code
........... //Some Code
),
Positioned(
left: 0,
top: 0,
child: Text("One"),
),
],0
)
),

Trying to create a method to control font size. Flutter App

I'm trying to create a font size control, the idea is that the user can change the font size of the entire app through the Slider, drag this bar and adjust it like 14px, 16px, 18px, 20px... minimum and maximum. I also read that the best way to make the changes on several screens will be using the provider, what is your opinion on this choice?
This is the starting code.
class Settings extends StatefulWidget {
const Settings({Key? key}) : super(key: key);
#override
State<Settings> createState() => _SettingsState();
}
class _SettingsState extends State<Settings> {
double _rating = 20;
#override
void initState() {
SystemChrome.setEnabledSystemUIMode(SystemUiMode.immersive);
super.initState();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
elevation: 0,
backgroundColor: Colors.transparent,
iconTheme: IconThemeData(color: Colors.blue[900]),
title: const Text(
'Settings',
style: TextStyle(
color: Colors.black,
),
),
),
body: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
ListTile(
title: Text('Button'),
trailing: Icon(
Icons.arrow_forward_ios,
color: Colors.blue,
),
onTap: () {
showModalBottomSheet<void>(
context: context,
builder: (BuildContext context) {
return Container(
height: 200,
color: Colors.white,
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Text(
'Change font',
style: TextStyle(
),
),
),
Slider(
value: _rating,
min: 0,
max: 28,
divisions: 4,
label: _rating.round().toString(),
onChanged: (newRating) {
setState(() => _rating = newRating);
},
),
],
),
),
);
}
);
},
),
],
),
);
}
}
I have created a provider example it might help you
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
void main() {
runApp(MultiProvider(providers: [
ChangeNotifierProvider(create: (_) => SliderValue()),
], child: MyApp()));
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: SizableText(),
);
}
}
class SliderValue with ChangeNotifier {
double _value = 5;
double get value => _value;
void increment(double val) {
_value = val;
notifyListeners();
}
}
class SizableText extends StatefulWidget {
const SizableText({Key? key}) : super(key: key);
#override
State<SizableText> createState() => _SizableTextState();
}
class _SizableTextState extends State<SizableText> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("AppBar")),
body: Center(
child: Column(
children: <Widget>[
Container(
margin: EdgeInsets.only(right: 10),
decoration: new BoxDecoration(
color: Colors.blue,
borderRadius: new BorderRadius.all(new Radius.circular(5.0)),
boxShadow: [
new BoxShadow(
color: Colors.black38,
offset: new Offset(0.0, 2.0),
blurRadius: 10)
]),
child: new Slider(
value: context.watch<SliderValue>().value,
activeColor: Colors.white,
inactiveColor: Colors.white,
onChanged: (double s) {
context.read<SliderValue>().increment(s);
},
divisions: 10,
min: 0.0,
max: 10.0,
),
),
Text1(text: 'Hello'),
Text1(text: 'Hi'),
],
),
),
);
}
}
class Text1 extends StatelessWidget {
Text1({this.text});
final String? text;
#override
Widget build(BuildContext context) {
return Text(text ?? '',
style: TextStyle(fontSize: 10 * context.watch<SliderValue>().value));
}
}
Basic idea is stored fonsize value in somewhere that Text can reach, state management will update the value of fonsize and notify to theres subscription. Im not using provider so im use an other state management is get to do this.
// ignore_for_file: prefer_const_constructors_in_immutables
import 'package:flutter/material.dart';
import 'package:get/get.dart';
class HomeController extends GetxController {
var fontSizeObx = RxDouble(12);
setFontsize(double value) => fontSizeObx.value = value;
}
class HomeRoute extends StatelessWidget {
HomeRoute({Key? key}) : super(key: key);
final controller = Get.put(HomeController());
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Obx(
() => Column(
children: [
Text(
'Hello world',
style: TextStyle(fontSize: controller.fontSizeObx.value),
),
Slider(
value: controller.fontSizeObx.value,
onChanged: controller.setFontsize,
divisions: 10,
min: 10.0,
max: 100.0,
)
],
),
),
),
);
}
}
You can try this
double _value = 5;
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("AppBar")),
body: Center(
child: Column(
children: <Widget>[
Container(
margin: EdgeInsets.only(right: 10),
decoration: new BoxDecoration(
color: Colors.blue,
borderRadius: new BorderRadius.all(new Radius.circular(5.0)),
boxShadow: [new BoxShadow(color: Colors.black38,
offset: new Offset(0.0, 2.0), blurRadius: 10)]),
child: new Slider(
value: _value,
activeColor: Colors.white,
inactiveColor: Colors.white,
onChanged: (double s) {
setState(() {
_value = s;
});
},
divisions: 10,
min: 0.0,
max: 10.0,
),
),
Text("Hello World", style: TextStyle(fontSize: 10 * _value)),
],
),
),
);
}

Is there any way to put custom toolbar on the keypad?

I want to put a custom toolbar on the keypad like the image above. Is it possible in flutter? or should I write code on the iOS or Android side?
You can copy paste run full code below
Please see working demo below
You can use package https://pub.dev/packages/keyboard_overlay
Step 1: Use with HandleFocusNodesOverlayMixin
Step 2: Use FocusNodeOverlay for focusNode
Step 3: Use GetFocusNodeOverlay and set _focusNodeOverlay = GetFocusNodeOverlay(
Step 4: TextField use TextField(focusNode: _focusNodeOverlay,
code snippet
class _MyHomePageState extends State<MyHomePage>
with HandleFocusNodesOverlayMixin {
FocusNodeOverlay _focusNodeOverlay;
#override
void initState() {
_focusNodeOverlay = GetFocusNodeOverlay(
child: TopKeyboardUtil(
Container(
color: Colors.white,
height: 45,
width: MediaQueryData.fromWindow(ui.window).size.width,
child: Row(
children: [
GestureDetector(
child: Icon(Icons.save),
onTap: () => print("click"),
),
...
Spacer(),
Container(
width: 60,
child: Center(
child: DoneButtonIos(
backgroundColor: Colors.white,
textColor: Colors.green,
label: 'Post',
onSubmitted: () {
print("submit");
},
platforms: ['android', 'ios'],
),
),

Yes there is a way around in the flutter to achieve this.
Create a widget of the toolbar you want to add.
Set it visible on input focus.
For reference I am sharing the code how I achieve that.
class InputDoneView extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Container(
width: double.infinity,
color: Style.lightGrey,
child: Align(
alignment: Alignment.topRight,
child: Padding(
padding: const EdgeInsets.only(top: 1.0, bottom: 1.0),
child: CupertinoButton(
padding: EdgeInsets.only(right: 24.0, top: 2.0, bottom: 2.0),
onPressed: () {
FocusScope.of(context).requestFocus(new FocusNode());
},
child: Text(
"Done",
style: TextStyle(color: Style.primaryColor,fontWeight: FontWeight.normal)
),
),
),
),
);
}
}
To call this in your main view when input field is focused in and out.
showOverlay(BuildContext context) {
if (overlayEntry != null) return;
OverlayState overlayState = Overlay.of(context);
overlayEntry = OverlayEntry(builder: (context) {
return Positioned(
bottom: MediaQuery.of(context).viewInsets.bottom, right: 0.0, left: 0.0, child: InputDoneView());
});
overlayState.insert(overlayEntry);
}
removeOverlay() {
if (overlayEntry != null) {
overlayEntry.remove();
overlayEntry = null;
}
}

Flutter: How to create a beautiful Curve oval shape Container / Divider between other widgets in Flutter

How to create this beautiful curve shape divider in a flutter App.
Simply use this customDivider as your divider
customDivider(String title) {
return Row(
children: [
Expanded(
child: Container(
color: Colors.white,
height: 10,
),
),
Container(
padding: EdgeInsets.all(10),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(13),
color: Colors.white,
),
child: Center(child: Text(title)),
),
Expanded(
child: Container(
color: Colors.white,
height: 10,
),
),
],
);
}
Here is an example
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
visualDensity: VisualDensity.adaptivePlatformDensity,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.grey,
appBar: AppBar(
title: Text(widget.title),
),
body: ListView.builder(
itemCount: 5,
shrinkWrap: true,
itemBuilder: (context, index) => listItem(index),
),
);
}
customDivider(String title) {
return Row(
children: [
Expanded(
child: Container(
color: Colors.white,
height: 10,
),
),
Container(
padding: EdgeInsets.all(10),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(13),
color: Colors.white,
),
child: Center(child: Text(title)),
),
Expanded(
child: Container(
color: Colors.white,
height: 10,
),
),
],
);
}
listItem(int index) {
return Column(
children: [
Container(
height: 200,
width: 200,
margin: EdgeInsets.all(10),
color: index.isEven ? Colors.orange : Colors.deepPurpleAccent,
),
customDivider("your title"),
],
);
}
}
OUTPUT:
There can be many ways to do this in flutter. This is one of the simplest approach.
main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: SafeArea(
child: SO(),
),
);
}
}
class SO extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.pink.shade100,
appBar: AppBar(),
body: Center(
child: CapsuleWidget(
label: 'organizing data'.toUpperCase(),
ribbonHeight: 8,
),
),
);
}
}
class CapsuleWidget extends StatelessWidget {
final Color fillColor;
final Color textColor;
final String label;
final double ribbonHeight;
final double ribbonRadius;
const CapsuleWidget({
Key key,
this.fillColor = Colors.white,
this.textColor = Colors.black,
#required this.label,
#required this.ribbonHeight,
this.ribbonRadius = 1000,
}) : super(key: key);
#override
Widget build(BuildContext context) {
return Row(
children: <Widget>[
Expanded(
child: Container(
height: ribbonHeight,
color: fillColor,
),
),
Container(
decoration: BoxDecoration(color: fillColor, borderRadius: BorderRadius.circular(ribbonRadius)),
child: Padding(
padding: const EdgeInsets.all(12.0),
child: Text(
label,
style: TextStyle(color: textColor, fontWeight: FontWeight.w500),
),
),
),
Expanded(
child: Container(
height: ribbonHeight,
color: fillColor,
),
),
],
);
}
}
it use Stack class
link url : https://api.flutter.dev/flutter/widgets/Stack-class.html
pseudo code
Stack {
Container(), // background
Contanier(), // white Line
Text() , // center Text
}
