How can I combine multiple textfields using Flutter? - flutter

How can I stack multiple textfields like this? I am trying to replicate this screen.
I've tried creating a Container with rounded borders, with a Column as the child containing multiple textfields. But the textfields extend past the border of the Container and the margin between them is too big.
My code so far:
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
class Administration extends StatefulWidget {
const Administration({Key? key}) : super(key: key);
#override
State<Administration> createState() => _AdministrationState();
}
class _AdministrationState extends State<Administration> {
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.grey[100],
body: Column(children: [
CupertinoNavigationBar(
automaticallyImplyLeading: false,
leading: IconButton(
icon: const Icon(
Icons.chevron_left,
size: 23,
),
color: Colors.grey,
onPressed: () {
Navigator.of(context).pop();
}),
trailing: const Icon(
Icons.account_circle,
size: 30.0,
color: Colors.grey,
),
middle: const Text('New Event'),
),
SizedBox(height: 15.0),
Container(
child: Column(
children: [],
),
)
],
)
);
}
}

From the image i see created a example for you:
import 'package:flutter/material.dart';
void main() {
runApp(const MaterialApp(
home: MyApp(),
));
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('sampla app'),
),
body: Container(
color: const Color(0xff1c1c1d),
child: Column(
children: [
const SizedBox(
height: 50,
),
Container(
margin: const EdgeInsets.all(10.0),
decoration:
BoxDecoration(color: const Color(0xff4c4c54), borderRadius: BorderRadius.circular(10.0)),
child: Column(
children: [
const Padding(
padding: EdgeInsets.only(left: 20.0),
child: TextField(
decoration: InputDecoration(
labelText: 'Title',
labelStyle: TextStyle(color: Colors.grey),
border: InputBorder.none,
),
),
),
Container(
margin: const EdgeInsets.only(left: 20),
height: 0.2,
color: Colors.grey,
),
const Padding(
padding: EdgeInsets.only(left: 20.0),
child: TextField(
decoration: InputDecoration(
labelText: 'Location or Video Call',
labelStyle: TextStyle(color: Colors.grey),
border: InputBorder.none,
),
),
),
],
),
),
],
),
),
);
}
}
Adding the image as well for how it looks.
Let me know if this works for you.

See blank white page after adding row in column

I want to create a login page. In this page, I need to have "forgot your password" and "remember me" in a same line, so I used row. When I hot reload it, it shows me a blank, white page.
I tried a row in container and adding that container to my column and still having that black page.
It has no problem if I add them normally (in two line), but I want them in a same line.
(If you have any suggestion for better and cleaner code, please tell me. I accept any suggestion)
Here is my code after a lot of changes:

I would like to know if anyone has other suggestions to achieve it.
Following is the code for the custom appbar and search widget:

Change TabbarView in Flutter When pressed button from another class and also need to make swipe-able

Hey I m new in flutter now m stuck with the tab bar I have four files (Class), the first one is the parent file and the other three files(Class) are the child.
Now I want to change tabbarview when I clicked the button from the child class.
I also shared my sample code please help me.
This is My Parent Class
class AddItemTab extends StatefulWidget {
const AddItemTab({Key? key}) : super(key: key);
#override
_AddItemTabState createState() => _AddItemTabState();
}
class _AddItemTabState extends State<AddItemTab> {
final List<Widget> _fragments = [
const ProductPurchase(),
const ProtectionProduct(),
const RoomProduct()
];
int _page = 0;
#override
Widget build(BuildContext context) {
return DefaultTabController(
length: 3,
child: Scaffold(
backgroundColor: MyColor.backgroundColor,
body: Padding(
padding: const EdgeInsets.only(
top: 50.0, right: 20.0, left: 20.0, bottom: 20.0),
child: Container(
child: Column(
children: [
Row(
children: [
Align(
alignment: Alignment.centerLeft,
child: IconButton(
padding: EdgeInsets.zero,
constraints: BoxConstraints(),
onPressed: () {
Navigator.of(context).pop();
},
icon: const Icon(Icons.arrow_back_ios),
),
),
Text("Back"),
],
),
SizedBox(
height: 15,
),
const Align(
alignment: Alignment.centerLeft,
child: Text(
'Add an item',
style: TextStyle(
color: Colors.black,
fontSize: 34,
fontFamily: 'Inter',
fontWeight: FontWeight.w700,
),
)),
const SizedBox(
height: 15,
),
Container(
height: 55,
width: double.infinity,
child: const TabBar(
indicator: BoxDecoration(
color: MyColor.buttonColor,
borderRadius: BorderRadius.all(
Radius.circular(5),
),
),
indicatorWeight: 5,
indicatorPadding: EdgeInsets.only(top:50),
// controller: _tabController,
labelColor: Colors.black,
tabs: [
Tab(
child: Text(
"Purchase",
textAlign: TextAlign.center,
),
),
Tab(
text: 'Protection',
),
Tab(
text: 'Room',
),
],
),
),
const SizedBox(height: 20),
Expanded(
child: TabBarView(
children: [
_fragments[0],
_fragments[1],
_fragments[2],
],
))
],
),
),
)),
);
}
}
This is My Child Class
class ProductPurchase extends StatefulWidget {
const ProductPurchase({Key? key}) : super(key: key);
#override
_ProductPurchaseState createState() => _ProductPurchaseState();
}
class _ProductPurchaseState extends State<ProductPurchase> {
final List<Widget> _fragments = [
const ProtectionProduct(),
];
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: MyColor.backgroundColor,
body: Stack(
children: [
Padding(
padding: EdgeInsets.only(bottom: 50),
child: Align(
alignment: Alignment.bottomCenter,
child: ElevatedButton(
style: ElevatedButton.styleFrom(
padding: EdgeInsets.zero,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10)),
elevation: 5,
),
onPressed: () {
// Navigator.of(context).push(MaterialPageRoute(
// builder: (context) => ProductView()));
// _fragments[0];
},
child: Ink(
decoration: BoxDecoration(
color: MyColor.buttonColor,
borderRadius: BorderRadius.circular(10)),
child: Container(
width: 250,
padding: const EdgeInsets.all(15),
constraints: const BoxConstraints(minWidth: 88.0),
child: const Text('Go To Next Tabbar View',
textAlign: TextAlign.center,`enter code here`
style: TextStyle(
fontSize: 18,
fontWeight: FontWeight.bold,
color: Colors.white)),
),
),
),
),
),
],
),
);
}
}
You need to use TabController for this , while you already have tab Bar and tab Bar view, you can do it like
class _AddItemTabState extends State<AddItemTab>
with SingleTickerProviderStateMixin {
final List<Widget> _fragments = [
.....
];
late final TabController controller = TabController(length: 3, vsync: this);
#override
Widget build(BuildContext context) {
........
child: TabBar(
controller: controller,
......
Expanded(
child: TabBarView(
controller: controller,
And to move n index, here 2
onPressed: () {
controller.animateTo(2);
},
To call from different widget using callback method
class ProductPurchase extends StatefulWidget {
final VoidCallback callback;
const ProductPurchase({Key? key, required this.callback}) : super(key: key);
.....
onPressed: (){
widget.callback();
},
Once you used this widget, provide
ProductPurchase(callback: (){
controller.animateTo(2);
},);
class ProductPurchase extends StatefulWidget {
final VoidCallback callback;
const ProductPurchase({Key? key, required this.callback}) : super(key: key);
#override
_ProductPurchaseState createState() => _ProductPurchaseState();
}
class _ProductPurchaseState extends State<ProductPurchase> {
#override
Widget build(BuildContext context) {
return Scaffold(
// backgroundColor: MyColor.backgroundColor,
body: Stack(
children: [
Padding(
padding: EdgeInsets.only(bottom: 50),
child: Align(
alignment: Alignment.bottomCenter,
child: ElevatedButton(
style: ElevatedButton.styleFrom(
padding: EdgeInsets.zero,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10)),
elevation: 5,
),
onPressed: () {
widget.callback(); //this
},
child: Ink(
decoration: BoxDecoration(
color: MyColor.buttonColor,
borderRadius: BorderRadius.circular(10)),
child: Container(
width: 250,
padding: const EdgeInsets.all(15),
constraints: const BoxConstraints(minWidth: 88.0),
child: const Text('Go To Next Tabbar View',
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 18,
fontWeight: FontWeight.bold,
color: Colors.white)),
),
),
),
),
),
],
),
);
}
}
And fragments
late final List<Widget> _fragments = [
ProductPurchase(
callback: () {
controller.animateTo(3);
},
),
Container(color: Colors.cyanAccent, child: Stack(children: [Text("fsA")])),
Text("2A")
];

How to reduce the white space beside the drawer icon in Flutter?

In my flutter project, I have set one custom drawer.
Here's code for custom drawer-
class AppDrawer extends StatelessWidget {
#override
Widget build(BuildContext context) {
double defaultScreenWidth = 400.0;
double defaultScreenHeight = 810.0;
ScreenUtil.instance = ScreenUtil(
width: defaultScreenWidth,
height: defaultScreenHeight,
allowFontScaling: true,
)..init(context);
return SizedBox(
width: MediaQuery.of(context).size.width * 0.70,
child: Drawer(
child: Container(
color: Colors.black87,
child: ListView(
padding: EdgeInsets.zero,
children: <Widget>[
SizedBox(height: ScreenUtil.instance.setHeight(30),),
_createDrawerItem(
icon: Icons.keyboard_arrow_right,
text: 'English to Bangla',
onTap: () =>
Navigator.pushReplacementNamed(context, Routes.englishToBangla)),
Padding(
padding: EdgeInsets.only(left:ScreenUtil.instance.setWidth(20), right: ScreenUtil.instance.setWidth(20)),
child: Divider(
height: ScreenUtil.instance.setHeight(10),
color: Colors.grey,
),
),
],
),
),
),
);
}
Widget _createHeader() {
return DrawerHeader(
margin: EdgeInsets.zero,
padding: EdgeInsets.zero,
decoration: BoxDecoration(
image: DecorationImage(
fit: BoxFit.fill,
image: AssetImage('path/to/header_background.png'))),
child: Stack(children: <Widget>[
Positioned(
bottom: 12.0,
left: 16.0,
child: Text("Flutter Step-by-Step",
style: TextStyle(
color: Colors.white,
fontSize: 20.0,
fontWeight: FontWeight.w500))),
]));
}
Widget _createDrawerItem(
{IconData icon, String text, GestureTapCallback onTap}) {
return ListTile(
title: Padding(
padding: EdgeInsets.only(left: ScreenUtil.instance.setWidth(10)),
child: Row(
children: <Widget>[
Container(
decoration: BoxDecoration(
shape: BoxShape.circle,
color: Colors.teal
),
child: Icon(icon, color: Colors.white,)
),
Padding(
padding: EdgeInsets.only(left: ScreenUtil.instance.setWidth(10)),
child: Text(text, style: TextStyle(color: Colors.white, fontWeight: FontWeight.bold, fontSize: ScreenUtil.instance.setSp(14) ),),
)
],
),
),
onTap: onTap,
);
}
}
Here's code for the toolBar which is shown beside the drawer icon-
class SearchAppBar extends StatefulWidget implements PreferredSizeWidget {
final PatternCallback onPatternSelected;
SearchAppBar(this.onPatternSelected, {Key key})
: preferredSize = Size.fromHeight(90),
super(key: key);
#override
final Size preferredSize; // default is 56.0
#override
_SearchAppBarState createState() => _SearchAppBarState();
}
class _SearchAppBarState extends State<SearchAppBar> {
TextEditingController _searchTextController = TextEditingController();
#override
Widget build(BuildContext context) {
double defaultScreenWidth = 400.0;
double defaultScreenHeight = 810.0;
ScreenUtil.instance = ScreenUtil(
width: defaultScreenWidth,
height: defaultScreenHeight,
allowFontScaling: true,
)..init(context);
return Container(
color: Colors.white,
child: Row(
children: <Widget>[
Expanded(
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(3),
),
child: Theme(
data:
Theme.of(context).copyWith(primaryColor: Color(0xFFff9900)),
child: TextFormField(
autofocus: false,
style: TextStyle(fontSize: ScreenUtil.instance.setSp(18)),
keyboardType: TextInputType.text,
controller: _searchTextController,
decoration: InputDecoration(
border: InputBorder.none,
hintText: 'Search for any word you want',
hintStyle:
TextStyle(fontSize: ScreenUtil.instance.setSp(16)),
contentPadding: EdgeInsets.symmetric(
vertical: 14,
horizontal: 10),
),
onChanged: (String value) {
widget.onPatternSelected(value);
},
),
),
),
),
Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(0),
),
child: InkWell(onTap: (){
if(_searchTextController.text.isNotEmpty) {
Navigator.of(context).push(MaterialPageRoute(builder: (context)=>WordDetailScreen(_searchTextController.text.toLowerCase())));
}
},
child: Icon(Icons.search, color: Colors.blue,))),
SizedBox(width: 15)
],
),
);
}
}
And then, in the class where I want to use this drawer, I have called inside Scaffold like below-
drawer: AppDrawer()
But the problem is this causing a white space beside the drawer icon like below image-
And I am having no idea from where this extra padding or margin is happening. So, I need a solution to reduce this extra white space beside the drawer icon.
You can use Transform.translate to move the search bar to the left:
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
leading: Builder(builder: (context) {
return IconButton(
icon: Icon(Icons.menu),
onPressed: () => Scaffold.of(context).openDrawer(),
);
}),
title: Transform.translate(
offset: Offset(-30.0, 0.0),
child: Text('this is the title') // here you can put the search bar
),
),
drawer: Drawer(
),
);
}
Just add a property called "titleSpacing" in your AppBar Tag,
Sample
appBar: AppBar(
titleSpacing: 0, //Add this line to your code
title: Text(widget.title),
leading: Icon(Icons.android),
),

Styling of Cupertino Picker in Flutter

I have tried to implement a layout like this using flutter.
I have used the Cupertino Picker Class for that.
But it just looks not as good as I want it to look.
I have tried to fix it by using the properties, that are listed on the flutter website, but I did not find any better solution. How can I fix this issue or is there even another widget that is better in this case?
My code looks like this:
Widget build(BuildContext context) {
return CupertinoPageScaffold(
navigationBar: CupertinoNavigationBar(
backgroundColor: Colors.red,
),
child: Container(
child: Center(
child: CupertinoPicker(
itemExtent: 40,
diameterRatio: 5,
offAxisFraction: 10,
backgroundColor: Colors.black54,
onSelectedItemChanged: (int index) {
print(index);
},
children: <Widget>[
Text('Tap', style: TextStyle(color:Colors.white)),
Text('Colorbattle',style: TextStyle(color:Colors.white)),
Text('Patience',style: TextStyle(color:Colors.white)),
],
))));
}
}
Playing around your code, I've tried to implement the same behavior. I've observed that changing the values of diameterRatio and offAxisFraction could change the way your UI look like. In my sample, the values of diameterRatio and offAxisFraction is 10 and -1 respectively. Just imagine this kind of roulette:
diameterRatio is the diameter of the cylinder and offAxisFraction is the axis where the side of the cylinder is facing. To mimic the example in the picture, set the value of the offAxisFraction to a positive value, in the implementation shown below, I've set it to 10.
Below is an example of copy the behavior of the UI you're trying to replicate:
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
void main() {
runApp(const 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: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
#override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return CupertinoPageScaffold(
navigationBar: CupertinoNavigationBar(
backgroundColor: Colors.red,
),
child: Center(
child: Container(
// color: Colors.black54,
decoration: BoxDecoration(
border: Border.all(color: Colors.white),
borderRadius: BorderRadius.all(
Radius.circular(15),
),
),
width: 200.0,
height: 150.0,
child: Center(
child: CupertinoPicker(
itemExtent: 40,
diameterRatio: 10,
offAxisFraction: -1,
backgroundColor: Colors.black54,
onSelectedItemChanged: (int index) {
print(index);
},
children: <Widget>[
Align(
alignment: Alignment.centerRight,
child: Padding(
padding: const EdgeInsets.only(right: 40.0),
child: Text(
'Estimate',
style: TextStyle(color: Colors.white),
),
),
),
Align(
alignment: Alignment.centerRight,
child: Padding(
padding: const EdgeInsets.only(right: 40.0),
child: Text(
'Random',
style: TextStyle(color: Colors.white),
),
),
),
Align(
alignment: Alignment.centerRight,
child: Padding(
padding: const EdgeInsets.only(right: 40.0),
child: Text(
'Colorbattle',
style: TextStyle(color: Colors.white),
),
),
),
Align(
alignment: Alignment.centerRight,
child: Padding(
padding: const EdgeInsets.only(right: 40.0),
child: Text(
'Patience',
style: TextStyle(color: Colors.white),
),
),
),
Align(
alignment: Alignment.centerRight,
child: Padding(
padding: const EdgeInsets.only(right: 40.0),
child: Text(
'Tap',
style: TextStyle(color: Colors.white),
),
),
),
],
),
),
),
),
);
}
}
Output:
