Add more fields after a listview.builder

I have a statefull layout with a listview.builder inside the builder I have a couple of expansionTile widgets
How do I show the entire list on the screen and add some textform widget below the list?
I have added a Expanded widget around the list to allow for more widgets below it but the list gets cut at a certain point where I want to show the entire list and then the text widgets after
class ContactUsScreen extends StatefulWidget {
const ContactUsScreen({Key? key}) : super(key: key);
static const String contactRouteName = "/contactScreen";
#override
State<ContactUsScreen> createState() => _ContactUsScreenState();
}
class _ContactUsScreenState extends State<ContactUsScreen> {
#override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(

centerTitle: true,
),
body: CustomScrollView(
slivers: [

child: ListView.builder(
itemCount: salesList.length,
itemBuilder: (BuildContext context, int index) {
return Padding(

],
);
},
).toList(),
),
),
);
}),
),
SizedBox(height: 15,),
Text("Contact us directly",
style: TextStyle(fontWeight: FontWeight.w700,
fontSize: 20,
color: Colors.black),),
Form(
key: formKey,
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 15),
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
TextFormField(controller: fullNameController,
keyboardType: TextInputType.text,
decoration: InputDecoration(labelText: "Full Name",
hintText: "Full Name",
),
validator: (inputFieldFullName)
{
if(inputFieldFullName!.isEmpty)
{
return "Please enter your Full Name";
}
else
{
return null;
}
},
),
TextFormField(controller: contactNumberController,
keyboardType: TextInputType.number,
decoration: InputDecoration(labelText: "Contact Number",
hintText: "Contact Number",
),
validator: (inputFieldContactNumber)
{
if(inputFieldContactNumber!.isEmpty)
{
return "Please enter your contact number";
}
else
{
return null;
}
},
),
SizedBox(height: 5,),
ElevatedButton(
onPressed: () {
if(formKey.currentState!.validate())
{
//Send the email
}
else
{
const SnackBar snackBar = SnackBar(duration: Duration(seconds: 2), content: Text("Please correct the errors"));
ScaffoldMessenger.of(context).showSnackBar(snackBar);
}
},
child: Text("Submit"),
),
SizedBox(height: 20,),
],
),
),
),
//getContactForm(context, formKey),
],
),
)
],
)
),
);
}
}
The end result should be that we display the entire list of parent expansion tile, and then only after the textform fields

You have to use this structure:
CustomScrollView(
slivers: <Widget>[
SliverList(
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index) {
return ** first listview **
},
childCount: top.length,
),
),
SliverList(
delegate: SliverChildBuilderDelegate(
(BuildContext context, int index) {
return ** second listview **
},
childCount: bottom.length,
),
),
],
),

the above code is of statefulwidget ad it is fullscreen dialog
thats it can i know why my list is not updated
Well you will need implement a ListViewBuilder to do this and please, split your layout creation your build method isn't readable. I make some changes in your layout to be more readable and the source code has some comments to help you get what I changed. I hope it can help and also you can adapt this code to your needs.
class EditorPageState extends State<EditorPage> {
List<Widget> obj = List<Widget>();
GlobalKey formkey= GlobalKey<FormState>();
#override
Widget build(BuildContext context) {
obj.add( TextFormField(
textCapitalization: TextCapitalization.sentences,
maxLength: 50,
decoration: InputDecoration(
labelText: "TITLE",
hintText: "UR ARTICLE NAME"
),
));
obj.add(TextFormField(decoration: InputDecoration(
labelText: "Article's Propic",
hintText: "Only image Url is Accepted"
),));
return Scaffold(
appBar: AppBar(title: Text("data"),),
//you can use this property to easily create a bottom navigation
bottomNavigationBar: _buildBottomNavigator(), // this method return BottomNavigation layout
body: Padding(
padding: EdgeInsets.symmetric(horizontal: 16.0),
child: Form(
key: formkey,
/// here your question answer... you need implemet a listView builder
/// in every build this will create a new ListView getting itens of a especific list
child : ListView.builder(
itemCount: obj.length, // number of items in your list
//here the implementation of itemBuilder. take a look at flutter docs to see details
itemBuilder: (BuildContext context, int Itemindex){
return obj[Itemindex]; // return your widget
}),
),
),
);
}
//create your bottom navigation layout
Widget _buildBottomNavigator(){
return Container(
color: Colors.black54,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
IconButton(icon: Icon(Icons.format_bold),color: Colors.white,onPressed: (){
setState(() {
obj.add(TextFormField(
style: TextStyle(fontWeight: FontWeight.bold),
decoration: InputDecoration(
labelText: "heading"
),
));
});
},),
IconButton(icon: Icon(Icons.add),
onPressed: (){
print("on pressed");
setState(() {
obj.add( TextFormField(
style: TextStyle(fontWeight: FontWeight.bold),

});
}

text fitting the expandedlist header's width

am using my customized ExpandedList .. but the header is overflowed when the text is long ....
and this is how am using it:
new CustomExpansionPanelList2(
expansionCallback: (int index, bool isExpanded) {
setState(() {
faqList[index].isExpanded =
!faqList[index].isExpanded;
});
},
children: faqList.map((Faq i) {
return new ExpansionPanel(
headerBuilder:
(BuildContext context, bool isExpanded) {
return new Container(
child: new Row(
children: <Widget>[
SizedBox(child: Text(
i.question,
style:
TextStyle(color: Color(0xff606060)),
),),
],
),
);
},
isExpanded: i.isExpanded,
body: new Center(
child: new Padding(
padding: EdgeInsets.all(10.0),
child: Text(i.answer),
),
),
);
}).toList(),
),
I want the text to be in two lines or more is needed to make it fit the width of the Expanded list..
How to achieve this?
Just replace SizedBox by Expanded in the headerBuilder
return new Container(
child: new Row(
children: <Widget>[
Expanded(child: Text(
i.question,
style:
TextStyle(color: Color(0xff606060)),
),),
],
),
);

How can I remove internal padding on a RadioListTile so I can use 3 RadioListTiles in a row?

I am pretty new to Flutter and Dart and I can't seem to find any hints for this particular topic. I am trying to put 3 RadioListTiles in a Row like so:
Row(
children: [
Expanded(
child:RadioListTile<GoalSelection>(
title: Text(
'Net',
style: Theme.of(context).textTheme.body1,
),
value: GoalSelection.net,
groupValue: _goalSelection,
onChanged: (GoalSelection value) {
setState(() {
_goalSelection = value;
});
},
),
),
Expanded(
child: RadioListTile<GoalSelection>(
title: Text(
'Gross',
style: Theme.of(context).textTheme.body1,
),
value: GoalSelection.gross,
groupValue: _goalSelection,
onChanged: (GoalSelection value) {
setState(() {
_goalSelection = value;
});
},
),
),
Expanded(
child: RadioListTile<GoalSelection>(
title: Text(
'Salary',
style: Theme.of(context).textTheme.body1,
),
value: GoalSelection.salary,
groupValue: _goalSelection,
onChanged: (GoalSelection value) {
setState(() {
_goalSelection = value;
});
},
),
),
],
),
The buttons layout fine, but there seems to be a lot of wasted space for the label. I put a screenshot of what it currently looks like below. I have tried wrapping the Expanded, the RadioListTile, and the Text in Padding widgets (all one at a time) to manually set the padding to 0, but it didn't do anything. I have also tried to change Expanded to Flexible even though I didn't think that would change anything. I am at a loss now. Is there any way to get this layout to work? I am kind of assuming it is something really dumb that I am doing.
You can use Radio + text widget instead of RadioListTile. For removing internal padding in Radio widget set:
Radio(
visualDensity: const VisualDensity(
horizontal: VisualDensity.minimumDensity,
vertical: VisualDensity.minimumDensity),
materialTapTargetSize: MaterialTapTargetSize.shrinkWrap,
.....
),
You can use a Radio and Text widget in a row. But the Radio also has the same padding problem. To remove the padding you can put the Radio as a child of a SizedBox.
eg:- SizedBox(height: 20, width: 20, child: Radio(.......))
RadioListTile is used with the purpose of taking the full width in a vertical scroll list.
If you don't want this behavior, don't use it. Use Radio instead.
just set contentPadding: EdgeInsets.zero
RadioListTile(contentPadding: EdgeInsets.zero)
We can control the padding of the RadioListTile using Flexible widget. As you want to arrange 3 RadioListTiles inside a Row Widget. Please try with the below code, it will work.
Row(
children: <Widget>[
Flexible(
fit: FlexFit.loose,
child:
RadioListTile(
title: const Text('hello'),
onChanged: (value) {
setState(() {});
},
),
),
Flexible(
fit: FlexFit.loose,
child:
RadioListTile(
title: const Text('Lafayette'),
onChanged: (value) {
setState(() {});
},
),
)
],
),
Do, let me know. Once you tried with the above code. If it resolved you problem, please accept my answer as useful and provide your valuable comments.
I got the same problem. You could try to customize with Radio, Text, InkWell, Padding.
class LabeledRadio extends StatelessWidget {
const LabeledRadio({
this.label,
this.padding,
this.groupValue,
this.value,
this.onChanged,
});
final String label;
final EdgeInsets padding;
final bool groupValue;
final bool value;
final Function onChanged;
#override
Widget build(BuildContext context) {
return InkWell(
onTap: () {
if (value != groupValue)
onChanged(value);
},
child: Padding(
padding: padding,
child: Row(
children: <Widget>[
Radio<bool>(
groupValue: groupValue,
value: value,
onChanged: (bool newValue) {
onChanged(newValue);
},
),
Text(label),
],
),
),
);
}
}
// ...
bool _isRadioSelected = false;
#override
Widget build(BuildContext context) {
return Scaffold(
body: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <LabeledRadio>[
LabeledRadio(
label: 'This is the first label text',
padding: const EdgeInsets.symmetric(horizontal: 5.0),
value: true,
groupValue: _isRadioSelected,
onChanged: (bool newValue) {
setState(() {
_isRadioSelected = newValue;
});
},
),
LabeledRadio(
label: 'This is the second label text',
padding: const EdgeInsets.symmetric(horizontal: 5.0),
value: false,
groupValue: _isRadioSelected,
onChanged: (bool newValue) {
setState(() {
_isRadioSelected = newValue;
});
},
),
],
),
);
}
The documentation: https://api.flutter.dev/flutter/material/RadioListTile-class.html#material.RadioListTile.3
This is how I fix the padding:
enum ContactSex { nam, nu, khac }
class CreateContactScreen extends StatefulWidget {
static const routeName = './create_contact';
#override
_CreateContactScreenState createState() => _CreateContactScreenState();
}
class _CreateContactScreenState extends State<CreateContactScreen> {
ContactSex _contaxtSex = ContactSex.nu;
final _form = GlobalKey<FormState>();
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(
'TẠO LIÊN HỆ',
style: kHeaderTextStyle,
),
actions: <Widget>[
FlatButton(
onPressed: () {
Navigator.pop(context);
},
child: Text('XONG', style: TextStyle(color: Colors.white),),
)
],
),
body: Container(
padding: EdgeInsets.symmetric(horizontal: 15.0, vertical: 20.0),
child: Form(
key: _form,

}
return null;

TextFormField(

}
You just need to set the "dense" property to true, example:
RadioListTile<String>(
title: "My radio",
dense: true, // <= here it is !
value: '1',
);
you should achieve this manually like
make a group of Radio() and Text() and wrap with InkWell() for state handling. now remove extra space of radio by materialTapTargetSize: MaterialTapTargetSize.shrinkWrap, That's it. Get idea by sample code.
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
InkWell(
onTap: () {
setState(() {
_radioVenue = 0;
});
},
child: Row(
children: [
Radio(
materialTapTargetSize:
MaterialTapTargetSize.shrinkWrap,
activeColor: primaryColor,
groupValue: _radioVenue,
onChanged: (value) {},
value: 0,
),
Text('From our list')
],
),
),
InkWell(
onTap: () {
setState(() {
_radioVenue = 1;
});
},
child: Row(
children: [
Radio(
materialTapTargetSize:
MaterialTapTargetSize.shrinkWrap,
activeColor: primaryColor,
groupValue: _radioVenue,
onChanged: (value) {},
value: 1,
),
Text('From our list')
],
),
),
],
),
We covered both both the issues in this sample.
Removed extra spaces.
whole group is selectable radio + text, Now it behaves like RadioListTile().
Simply use RadioListTile and remove extra padding, by default it's 18
RadioListTile(contentPadding: EdgeInsets.symmetric(horizontal: 0.0)),
OR
RadioListTile(
contentPadding: EdgeInsets.symmetric(horizontal: 0.0),
value: null,
groupValue: null,
onChanged: null,
),
glad to answer
I was looking for same question and ended up on Flutter Documentation
I was working on Column and RadioListTile and I faced same issue, there's a horizontal padding between content inside RadioListTile
So, here it's the answer
Looking for this documentation ! RadioListTile content padding
Just add contentPadding: EdgeInsets.symmetric(horizontal: 0) and here you go, there's no horizontal padding anymore
Just copy paste this code and enjoy
Container(
height:35,
child: Row(
children: [
Radio(
groupValue: data.selected,
value: e,
onChanged: (DataBindModel? value) {
listener.value = MultiChoiceData(selected: value, items: listener.value.items);
onChanged(value);
onSelected(value);
},
),
Text(
e.value,
style: body14,
)
],
),
)
Copy the RadioListTile code and create your on new new file and paste it in there.
Remove the imports causing errors:
import 'package:flutter/widgets.dart'; // leave it
import 'package:flutter/material.dart'; //add
import 'list_tile.dart'; //remove
import 'radio.dart'; //remove
import 'theme.dart'; //remove
import 'theme_data.dart'; //remove
Then add the following padding to it, like this:
//Inside the file locate this widget and Add the padding or remove it. I needed to remove it and add 5.
return MergeSemantics(
child: ListTileTheme.merge(
contentPadding: EdgeInsets.only( // Add this
left: 5,
right: 0,
bottom: 0,
top: 0
),
selectedColor: activeColor ?? Theme.of(context).accentColor,
child: ListTile(
leading: leading,
title: title,
subtitle: subtitle,
trailing: trailing,
isThreeLine: isThreeLine,
dense: dense,
enabled: onChanged != null,
onTap: onChanged != null && !checked ? () { onChanged(value); } : null,
selected: selected,
),
),
);
then Import the file into your project like this:
import 'package:Project_Name/common/customComponets/custom_radio_list_tile.dart' as CustomRadioListTile;
Then use it like this:
CustomRadioListTile.RadioListTile(); // and that's how I managed to do it. Thought I should share.
This is my way of reducing the space. I have three Radio in one row.
Row(
children: [
Expanded(
child: RadioListTile(
contentPadding: EdgeInsets.all(0.0),
value: DayoffType.Range,
groupValue: _dayoffType,
title: Transform.translate(offset: const Offset(-18, 0), child: Text('Range')),
onChanged: (DayoffType? val) {
setState(() {
_dayoffType = val!;
});
},
),
),
Expanded(...Radio2...),
Expanded(...Radio3...)
)
