How can I add an Icon to to Box Decoration?

I want to add an Icon to Box Decoration like this you are seeing images on left side.
How do I add this with box decoration
Here is the code:
Container(
width: 307,
decoration: BoxDecoration(
border: Border.all(color: Colors.blueAccent),
borderRadius: BorderRadius.circular(10.0),
shape: BoxShape.rectangle,
),
child: CountryListPick(
onChanged: (list){
print(list?.name);
},
theme: CountryTheme(
labelColor: Colors.white,
isShowFlag:true,
isShowCode: false,
isShowTitle:true,
isDownIcon: true,
showEnglishName: true,
),
),
),

You can use this widget for a textfield with boxdecoration and icon:
TextFormField(
key: Key(key),
controller: controller,
decoration: InputDecoration(
prefixIcon: Icon(icon), // <-- left icon
hintText: hintText,
border: OutlineInputBorder( //<--- decoration border
borderRadius: BorderRadius.all(Radius.circular(90.0)),
borderSide: BorderSide.none,
),
filled: true,
),
)

You can use a row as a children of container
Container(
width: 307,
decoration: BoxDecoration(
border: Border.all(color: Colors.blueAccent),
borderRadius: BorderRadius.circular(10.0),
shape: BoxShape.rectangle,
),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Flexible(
child: Image.asset(
"assets/images/cover_placeholder.png",
height: 30,
width: 30,
fit: BoxFit.contain,
),
),
SizedBox(width: 12,),
Flexible(
child: CountryListPick(
onChanged: (list){
print(list?.name);
},
theme: CountryTheme(
labelColor: Colors.white,
isShowFlag:true,
isShowCode: false,
isShowTitle:true,
isDownIcon: true,
showEnglishName: true,
),
),
),
],
),
),

So you can use SizedBox or Container -
SizedBox(
width: 300.0,
height: 120.0,
child: Padding(
padding: const EdgeInsets.all(5.0),
child: Container(
child: Row(
children: <Widget>[
Material(
type: MaterialType.transparency,
child: Stack(
children: <Widget>[
Column(
children: <Widget>[
Container(
padding: const EdgeInsets.only(
top: 1.0, bottom: 1.0, right: 5.0),
height: 50.0,
width: 50.0,
decoration: BoxDecoration(
borderRadius:
BorderRadius.circular(15.0),
color: Colors.green[50],
),
child: IconButton(
icon: Icon(Icons.favorite),
color: Colors.red[700],
highlightColor: Colors.red,
onPressed: () {},
),
),
],
),
],
),
),
],
),
),
),
),

Widget Expanded height according to Listview content

I'm trying to put the height of the Expanded Widget to the size of the Listview inside it, but I'm not getting it, here's the code:
With the code below, the listviews are very small and shrunk and I would like to set a size or leave the auto size for the content, I already tried to change from Expanded to Flexible with fit: flexfit.loose and it didn't work either
class ProdutoPage extends GetView<ProdutosController> {
final controller = Get.find<ProdutosController>();

You column is quite complex, I suggest you to use CustomScrollView, reference.
In CustomScrollView:
change your ListView widget to SliverList
change your Padding widget to SliverPadding
wrap your Text widget in SliverToBoxAdapter
wrap your Divider widget in SliverToBoxAdapter
and see how it works.

How to make validation stepper when form inside bottomsheet?

This app make a stepper. In stepper I build add data and show bottomsheet. In bottomsheet we can add data from there, but in this case how to validate stepper when we click next steps read method bottomsheet (if user not filling field showing error in stepper).
This is the method bottomsheet:
class StepperclassState extends State<Stepperclass> {
void inputRekomen(){
final Formlist formProvider = Provider.of<Formlist>(context, listen: false);

I am not sure if this can help solve the problem, since the problem is not clear enough.
First, you need to wrap all if the steps form in Form, Set the key from the class property. for example:
final _formKey = GlobalKey<FormState>();
then on build method, on the Form widget set the key:
child: Form(
key: _formKey,
...
and then on each TextFormField, put validator on it for example:
validator: (value) {
if (value!.isEmpty) {
return 'Name is required';
}
return null;
}
then, when you need validation/checking on another methods in bottomsheet just call these function:
if (!_formKey.currentState!.validate()) {
return 'Fill form correctly';
}

SingleChildScrollView doesn't work inside Column

I want scroll view in flutter but it doesn't work.
I put the SingleChildScrollView inside Align and the Align inside Stack then i put inside SingleChildScrollView Column ,

Does anyone know what could be the issue ?

I would suggest replacing the top Column widget with a ListView, that automatically resizes on keyboard input, whilst also supporting scrolling.
If you really want this setup as it is, you can edit your Scaffold with the parameter
resizeToAvoidBottomPadding: false
That should make the error disappear

Scaffold(
resizeToAvoidBottomInset: false, // set it to false
...
)
As Andrey said, you may have issues with scrolling, so you may try
Scaffold(
resizeToAvoidBottomInset: false, // set it to false
body: SingleChildScrollView(child: YourBody()),
)

With resizeToAvoidBottomPadding: false in Scaffold, You don't see all the widgets that are below the open textfield. The solution is to insert a container with a SingleChildScrollView inside. Example:
Container(
alignment: Alignment.center,
width: double.infinity,
height: double.infinity,
color: viewModel.color,
child: SingleChildScrollView(child:"Your widgets"));

you usually need to provide a scroll widget on top of your widgets because if you try to open the keyboard or change the orientation of your phone, flutter needs to know how to handle the distribution of the widgets on the screen.
Please review this resource, you can check the different options that flutter provide Out of the box, and choose the best option for your scenario.
https://flutter.io/widgets/scrolling/

wrap your child view into ListView will solve the prob. Please check this
class _LoginScreenState extends State<LoginScreen> {
#override
Widget build(BuildContext context) {
return new Scaffold(
body: new Container(
child: ListView(
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: new Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
new Padding(
padding: EdgeInsets.only(left: 1,top: 50,right: 1,bottom: 1),
child: new Text("jk", style: TextStyle(fontFamily: "mono_bold")),
),
new Padding(
padding: EdgeInsets.only(left: 1,top: 50,right: 1,bottom: 1),
child: new TextField(
style: new TextStyle(),
decoration: InputDecoration(
labelText: "Email",
contentPadding: EdgeInsets.all(8.0)
),
keyboardType: TextInputType.emailAddress,
)
),
new Padding(
padding: EdgeInsets.only(left: 1,top: 50,right: 1,bottom: 1),
child: new TextField(
style: new TextStyle(
),
decoration: InputDecoration(
labelText: "Password"
),
keyboardType: TextInputType.text,
obscureText: true,
),
),
],
),
),
],
)
),
);
}

wrap your column into SingleChildScrollView will solve the problem. Please check this:
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: Center(
child: SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
TextField(),
TextField(),
],
),
))));
}
And You also use for removing yellow black overflow line
resizeToAvoidBottomPadding: false
but in this case, TextField does not move up on click time.

wrap with SingleChildScrollView Widget here's my code to solve this situation:
it is best and easiest method
SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Hero(
tag: 'logo',
child: Container(
height: 200.0,
child: Image.asset('images/logo.png'),
),
),
SizedBox(
height: 48.0,
),
TextField(
onChanged: (value) {
//Do something with the user input.
},
decoration: kTextFieldDecoration.copyWith(hintText: 'Enter username'),
),
SizedBox(
height: 8.0,
),
TextField(
onChanged: (value) {
//Do something with the user input.
},
decoration: kTextFieldDecoration.copyWith(hintText: 'Enter password'),
),
SizedBox(
height: 24.0,
),
RoundedButton(
colour: Colors.blueAccent,
text: 'Register',
onPressed: () {
//later todo
},
),
],
),
),

You can set resizeToAvoidBottomInset: false for avoiding overflow, but you can't reach fields in bottom of page, which can be covered by keyboard.
Or you can wrap body of Scaffold inside SingleChildScrollView

You can enclose all the widgets within the ListView.
So you can scroll it and the overloaded will disappear.

you should add resizeToAvoidBottomInset: false, and put your button in child:SingleChildScrollView() like the following code below :
Widget build(BuildContext context) {
return Scaffold(
resizeToAvoidBottomInset: false,
appBar: PreferredSize(
preferredSize:const Size(double.infinity,100),
child:(ResponsiveLayout.isTinyLimit(context) ||
ResponsiveLayout.isTinyHeightLimit(context))
? Container()
: const AppBarWidget(),
),
body: Center(
child:SingleChildScrollView(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center ,
children: [
Text("Temperature"),
LineChartSample2(),
Text("Gas Level"),
LineChartSample2(),
on?Icon(Icons.lightbulb,
size:100,
color: Colors.lightBlue.shade700 ,
):const Icon(Icons.lightbulb_outline,
size:100,
),
ElevatedButton(
style: TextButton.styleFrom(
backgroundColor: on? Colors.green: Colors.white10),
onPressed: (){
dbR.child("movement").set({"Switch":!on});
setState(() {
on = !on;
});
},
child:on ? const Text("On"):const Text("Off"))
],
),
),
) ),
),
);

Put your content in to SingleChildScrollView and add a ConstrainedBox and try
https://api.flutter.dev/flutter/widgets/SingleChildScrollView-class.html

Wrap your top column inside SingleChildScrollView.
Make you layout scrollable.

You can wrap your Fields in single child ScrollView of Flutter.

This align items bottom to top,
Try this..
child: SizedBox(
height: MediaQuery.of(context).size.height,
child: SingleChildScrollView(
reverse: true,

Remove unwanted padding top and bottom
child: Container(
height: size.height,
width: size.width,
padding: EdgeInsets.only(
left: size.width * 0.15,
right: size.width * 0.15,
top: size.width * 0.15,
bottom: size.width * 0.15,
),
to change by this
child: Container(
height: size.height,
width: size.width,
padding: EdgeInsets.only(
left: size.width * 0.15,
right: size.width * 0.15,
),
This worked for me.

please set resizeToAvoidBottomPadding: false and set scrollPadding in textField

Instead of column widget try to use flex widget, which might solve your problem.

Try wrapping your main Column with
1.(ListView and give property shrinkWrap: true,) List view has property children: [], or
2.( SingleChildScrollView() )but it has only child: , .
Something like:
child: ListView(shrinkWrap: true, children: <Widget>[
new Column(children: <Widget>[
Container(
padding: EdgeInsets.all(120.0),
child: Center(
child: Icon(
Icons.headset_mic,

),
),
),
new Row(
children: <Widget>[
new Expanded(
child: new Padding(
padding: const EdgeInsets.only(left: 40.0),
child: new Text(
"EMAIL",
style: TextStyle(
fontWeight: FontWeight.bold,
color: Colors.redAccent,
fontSize: 15.0,
),
),
),
),
],
),
new Container(
width: MediaQuery.of(context).size.width,
margin: const EdgeInsets.only(
left: 40.0, right: 40.0, top: 10.0),
alignment: Alignment.center,
decoration: BoxDecoration(
border: Border(
bottom: BorderSide(

),
),

child: new Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.start,
