How can I add a container inside a textField? - flutter

I have tried wrapping the textField in a row and adding a container to the row but it throws an error and the rest part of the form doesn't render.
And using the prefix property for textField also doesn't work as the container is shown when the textField is pressed but I want it to be seen even when the textField is not active.
this is the required UI for the mobile no. field I'm trying to build


Container(
decoration: BoxDecoration(
color: Colors.grey[200],
borderRadius: BorderRadius.circular(8),
),
child: Row(
children: [
Container(
height: 50,
alignment: Alignment.center,
padding: const EdgeInsets.symmetric(
horizontal: 8,
),
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.only(
topLeft: Radius.circular(8),
bottomLeft: Radius.circular(8),
),
),
child: Text(
"+91",
style: TextStyle(
color: Colors.white,
),
),
),
Expanded(
child: Padding(
padding: const EdgeInsets.symmetric(
horizontal: 12,
),
child: TextField(
decoration: InputDecoration(
border: InputBorder.none,
hintText: "Mobile No."
),
),
),

],

The following assertion was thrown during layout:
A RenderFlex overflowed by 249 pixels on the bottom.
The relevant error-causing widget was:
Column Column:file:///xxxxxxx/lib/ecrans/auth/activation_screen.dart:54:26
The overflowing RenderFlex has an orientation of Axis.vertical.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.
The specific RenderFlex in question is: RenderFlex#1a283 relayoutBoundary=up5 OVERFLOWING
... needs compositing
... parentData: offset=Offset(20.0, 20.0) (can use size)
... constraints: BoxConstraints(0.0<=w<=371.4, h=148.1)

Wrap your main container with SingleChildScrollView instead of the Expanded
SingleChildScrollView(

decoration: BoxDecoration(

My second container is taking all the space.How to avoid that

The second Container which is in the red color is taking all the remaining space. How to avoid that. I want my second container to take the minimum space.

Remove parent Container height and set Column <mainAxisSize: MainAxisSize.min,>.
It is taking full height because of Container height and the default behavior of Column.
And to improve UI, use padding on Container<padding:x,child Column>
Container(
// height: 600,
decoration: const BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.all(
Radius.circular(60),
),
),
child: Padding(
padding: const EdgeInsets.only(top: 80.0, right: 50, left: 50),
child: Container(
padding: const EdgeInsets.all(40), //here padding
decoration: const BoxDecoration(
color: Colors.red,
borderRadius: BorderRadius.all(
Radius.circular(20),
),
),
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
TextFormField(
decoration: const InputDecoration(
border: UnderlineInputBorder(),
labelText: "Email or Phone Number"),
),
const SizedBox(
height: 20,
),
const TextField(
decoration: InputDecoration.collapsed(hintText: 'PassWord'),
),
],
),
),
),
),

Try below code hope its helpful to you. Just remove your container extra/large height
Container(
height: 180,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.all(
Radius.circular(
60,
),
),
),
child: Padding(
padding: const EdgeInsets.only(top: 80.0, right: 50, left: 50),

child: Column(
children: [
TextFormField(

SizedBox(

Overlap leading Icon on form input field in flutter

Trying to implement this style of login in flutter. Any ideas? Tried using the prefix icon and row but not really getting it.
Example Login Image

You can use an Stack with two children, one for the leading icon and the other for the text input. I wrote the code you need to implement what you want. So, I will share it with you. You only have to set up the colors and the text style as you prefer.
Here we go...
Column(
children: <Widget>[
Stack(
children: <Widget>[
Container(
margin: EdgeInsets.symmetric(vertical: 6.0),
height: 36.0,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(24.0),
boxShadow: [BoxShadow(blurRadius: 12.0)],
),
child: Padding(
padding: EdgeInsets.fromLTRB(70.0, 0.0, 30.0, 0.0),
child: TextFormField(
decoration: InputDecoration(
contentPadding: EdgeInsets.symmetric(vertical: 8.0),
border: InputBorder.none,
hintText: 'Username',
),
),
),
),
Container(
decoration: BoxDecoration(
color: Colors.white,
shape: BoxShape.circle,
boxShadow: [BoxShadow(blurRadius: 12.0)],
),
child: Padding(
padding: EdgeInsets.all(12.0),
child: Icon(Icons.person_outline),
),
),
],
),
SizedBox(height: 12.0),
Stack(
children: <Widget>[
Container(
margin: EdgeInsets.symmetric(vertical: 6.0),
height: 36.0,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(24.0),
boxShadow: [BoxShadow(blurRadius: 12.0)],
),
child: Padding(
padding: EdgeInsets.fromLTRB(70.0, 0.0, 30.0, 0.0),
child: TextFormField(
decoration: InputDecoration(
contentPadding: EdgeInsets.symmetric(vertical: 8.0),
border: InputBorder.none,
hintText: 'Password',
),
),
),
),
Container(
decoration: BoxDecoration(
color: Colors.white,
shape: BoxShape.circle,
boxShadow: [BoxShadow(blurRadius: 12.0)],
),
child: Padding(
padding: EdgeInsets.all(12.0),
child: Icon(Icons.lock_outline),
),
),
],
),
],
),
And the output is this:

How to style this kind of Text Field

I want to style this kind of TextField.
The main problem that I'm facing is to design the US$ part in leading the TextField. This is my code so far.
/// My Place Bid Text Field
Container(
decoration: BoxDecoration(
border: Border.all(color: Colors.grey),
borderRadius: BorderRadius.circular(4),
),
child: Row(
mainAxisSize: MainAxisSize.max,
children: [
SizedBox(
child: Container(
//width: mySize.width * 0.2,
//height: 50,
padding: const EdgeInsets.all(8),
decoration: BoxDecoration(
border: Border.all(color: Colors.grey),
borderRadius: BorderRadius.only(
topLeft: Radius.circular(4),
bottomLeft: Radius.circular(4),
),
color: Colors.grey[200]),
child: Text(
"RS \u20B9",
style: TextStyle(fontSize: 24),
),
),
),
Expanded(
child: TextField(
decoration: InputDecoration(
border: InputBorder.none,
labelText: "Place Bid",
labelStyle: TextStyle(fontSize: 24)),
),
),
],
),
),
Which gives me output
I know this question is not that complicated, but I'm still relatively new to flutter so your help would be much appreciated.

#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Sample"),
),
body: Padding(
padding: EdgeInsets.all(10),
child: Container(
decoration: BoxDecoration(
border: Border.all(
color: Colors.grey[500],
),
borderRadius: BorderRadius.all(Radius.circular(8))),
width: double.infinity,
height: 50,
child: Row(
children: <Widget>[
Container(
padding: EdgeInsets.all(10),
color: Colors.grey.shade300,
height: 50,
child: Align(
alignment: Alignment.center,
child: Text(

style: TextStyle(
fontSize: 24, fontWeight: FontWeight.bold),
),
)),
SizedBox(
width: 10,
),
Expanded(
child: Container(
height: 50,
child: TextField(
decoration: InputDecoration(
border: InputBorder.none,
hintText: "Enter Bid",
labelStyle: TextStyle(fontSize: 24)),
)))
],
),
),
));
}
Output

You can use the prefixIcon to add a widget at the beginning of the textfield:
Container(
child: Row(
children: [
Expanded(
child: TextField(
decoration: InputDecoration(
prefixIcon: Padding(
padding: const EdgeInsetsDirectional.only(start: 2.0),
child: Container(
padding: const EdgeInsets.all(13),
decoration: BoxDecoration(
border: Border.all(color: Colors.grey),
borderRadius: BorderRadius.only(
topLeft: Radius.circular(4),
bottomLeft: Radius.circular(4),
),
color: Colors.grey[200]),
child: Text(
"RS \u20B9",
style: TextStyle(fontSize: 24),
),
),
),
border: const OutlineInputBorder(),
labelText: 'Hint Text',
),
),
),
],
),
)

Based on your solution.
Notice the "IntrinsicHeight" widget. It makes all the children inside the child the same size (depending on the biggest one). The "Center" widget inside the prefix makes the Container go max height + center the text inside of it. Just make sure not to use IntrinsicHeight too much, since the docs state that it's a bit resource heavy.
Container(
width: double.infinity,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(10.0),
border: Border.all(color: Colors.grey[200]),
),
child: IntrinsicHeight(
child: Row(
children: <Widget>[
Container(
padding: EdgeInsets.symmetric(horizontal: 10.0),
decoration: BoxDecoration(
color: Colors.grey[100],
border: Border(
right: BorderSide(color: Colors.grey[200]),
),
),
child: Center(
child: Text(
'RS \u20B9',
style: TextStyle(fontSize: 24),
),
),
),
Expanded(
child: TextField(
decoration: InputDecoration(
contentPadding: EdgeInsets.symmetric(horizontal: 20.0, vertical: 10.0),
border: InputBorder.none,
labelText: "Place Bid",
),
),
),
],
),
),
),
The second code is almost the same, except there's no label after typing the text inside the TextField.
Container(
margin: EdgeInsets.symmetric(horizontal: 20.0),
width: double.infinity,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(10.0),
border: Border.all(color: Colors.grey[200]),
),
child: IntrinsicHeight(
child: Row(
children: <Widget>[
Container(
padding: EdgeInsets.symmetric(horizontal: 10.0),
decoration: BoxDecoration(
color: Colors.grey[100],
border: Border(
right: BorderSide(color: Colors.grey[200]),
),
),
child: Center(
child: Text(
'RS \u20B9',
style: TextStyle(fontSize: 24),
),
),
),
Expanded(
child: TextField(
decoration: InputDecoration(
contentPadding: EdgeInsets.symmetric(
horizontal: 20.0,
vertical: 20.0,
),
border: InputBorder.none,
hintText: "Place Bid",
),
),
),
],
),
),
),

Container(
decoration: BoxDecoration(
),
child: Row(
mainAxisSize: MainAxisSize.max,
children: [
SizedBox(
child: Container(
//width: mySize.width * 0.2,
//height: 50,
padding: const EdgeInsets.all(10),
decoration: BoxDecoration(
border:Border.all(color:Colors.grey),
borderRadius: BorderRadius.only(
topLeft: Radius.circular(4),
bottomLeft:Radius.circular(4),
),
color: Colors.grey[200]),
child: Text(
"RS \u20B9",
style: TextStyle(fontSize: 24),
),
),
),
Expanded(
child: TextField(

You could use prefixIcon property of InputDecorator to display somethig.
TextField(
decoration: InputDecoration(
prefixIcon: SizedBox(
width: 50,
child: Center(
child: Text(
'+91',
style: TextStyle(color: Colors.black),
),
),
),
),
),
You could also use prefix property but the text will disappear if text field is not focused.
If you want to add line after the prefix you could replace SizedBox with Container instead. And use border property.
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
prefixIcon: Container(
width: 50,
margin: EdgeInsets.only(right: 10),
decoration: BoxDecoration(
border: Border(
right: BorderSide(
color: Color(0xFF272727),
width: 1,
),
),
),
child: Center(
child: Text(
'+91',
style: TextStyle(color: Colors.black),
),
),
),
),
),
