Flutter Wrap Widget does not expand itself - flutter

I'm trying to create a calendar and I'm using Wrap widget to display days inside calendar. But I faced a problem. Wrap widget does not expand itself to every side that's why overflow happens. This is my code:
return Container(
height: MediaQuery.of(context).size.height * 0.40,
width: MediaQuery.of(context).size.width / 2,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(46.0),
color: Color(0xFFD6D6D6),
boxShadow: [
BoxShadow(
color: Color(0xFF000000).withOpacity(0.16),
offset: Offset(0, 10),
blurRadius: 20.0,
),
],
),
child: Column(
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
SizedBox(width: 8.0),
GestureDetector(
onTap: () {},
child: Icon(
Icons.arrow_back_ios,
color: Colors.white,
),
),
Text(
'${getMonthName(initialDate.month)}',
style: GoogleFonts.baloo(
color: Colors.white,
fontSize: 50.0,
fontWeight: FontWeight.w400,
),
),
GestureDetector(
onTap: () {},
child: Icon(
Icons.arrow_forward_ios,
color: Colors.white,
),
),
SizedBox(width: 8.0),
],
),
Container(
height: MediaQuery.of(context).size.height * 0.25,
width: MediaQuery.of(context).size.width / 2.5,
child: Row(
children: [
Wrap(
alignment: WrapAlignment.start,
direction: Axis.horizontal,
spacing: 2.0,
children: dayList == null
? SizedBox()
: dayList.map((e) {
return DaysContainer(
number: e,
);
}).toList(),
),
],
),
),
],
),
);
When I remove upper Row in Wrap, this time widget only goes to vertical even though I define Axis.horizontal.
DaysContainer class:
class DaysContainer extends StatelessWidget {
const DaysContainer({Key key, this.number, this.isAvailable})
: super(key: key);
final String number;
final bool isAvailable;
#override
Widget build(BuildContext context) {
return Container(
padding: EdgeInsets.all(8.0),
decoration: BoxDecoration(
color: Color(0xFFFFFFFF),
),
child: Center(
child: Text(
number,
style: GoogleFonts.baloo(
fontSize: 30.0,
color: Color(0xFFBFBFBF),
fontWeight: FontWeight.w400,
),
),
),
);
}
}
This is the result in Flutter Web:

Can anyone help me to figure out what is the problem in Wrap widget?

Please change your code with the following changes:
Removed Row widget outside Wrap
Defined your width of DaysContainer. Currently, the width of Container in DaysContainer has full width of parent widget. That is the reason why your time widget goes to vertical even though you define Axis.horizontal in Wrap widget.
By the way, you can add the properties runSpacing and spacing to your Wrap widget to give more space between your items in horizontal and vertical instead of using padding.

try to change to:
Container(
height: MediaQuery.of(context).size.height * 0.25,
width: MediaQuery.of(context).size.width / 2.5,
child: Wrap(
alignment: WrapAlignment.start,
direction: Axis.horizontal,
spacing: 2.0,
children: dayList == null
? SizedBox()
: dayList.map((e) {
...
class DaysContainer extends StatelessWidget {
const DaysContainer({Key key, this.number, this.isAvailable})
: super(key: key);
final String number;
final bool isAvailable;
#override
Widget build(BuildContext context) {
return Container(
width: 20,
height: 20,
margin: EdgeInsets.only(bottom: 2.0),
padding: EdgeInsets.all(8.0),
decoration: BoxDecoration(
color: Color(0xFFFFFFFF),

child: Center(
child: Text(
number,

fontSize: 30.0,

);
}

Container should have the same height

I want that the red container has the same height as the blue container. The problem is, that the height of the blue container changes depending of the amount of lines. It would also help if the red container starts on the same height as blue container. The goal is to have a functional bullet point in the middle of the first line
My code is:
import 'package:flutter/material.dart';
class InhaltGesetz extends StatelessWidget {
final String text;
const InhaltGesetz({
Key? key,
required this.text,
}) : super(key: key);
#override
Widget build(BuildContext context) {
return Row(
children: [
Expanded(
child: Container(
height: 70,
color: Colors.red,
child: const Align(
alignment: Alignment(0, -0.99),
child: Text(
'•',
style: TextStyle(fontSize: 25, color: Colors.white),
),
),
),
),
LayoutBuilder(
builder: (context, constraints) {
return Container(
width: 340,
color: Colors.blue,
child: SingleChildScrollView(
child: Padding(
padding: const EdgeInsets.fromLTRB(4, 8, 8, 8),
child: Text(
text,
style: const TextStyle(
fontSize: 15.5,
color: Colors.white,
fontWeight: FontWeight.bold,
),
),
),
),
);
},
),
],
);
}
}
I do not know what to do I tried to change the height manually with every container but i ended up with 9000+ lines of code and i will not do it any longer
You can use IntrinsicHeight widget(expensive), Follow this structure.
class InhaltGesetz extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Column(
children: [
IntrinsicHeight(
child: Row(
children: [
Container(
width: 200,
color: Colors.red,
child: const Align(
alignment: Alignment(0, -0.99),
child: Text(
'•',
style: TextStyle(fontSize: 25, color: Colors.white),
),
),
),
Container(
width: 340,
height: 200,
color: Colors.blue,
),
],
),
),
],
);
}

RenderFlex overflow error displayed while using the card type class inside a container - Flutter

I'm trying to display 2 cards inside a Container, but I'm getting the same RenderFlex error.
Can anyone help me out with this?
Here is the complete error:

),
),
Padding(

child: Column(

Navigator.push(
context,
MaterialPageRoute(builder: (context) => ProfileScreen()),
);
},
),
color: Colors.transparent,
),
),
);
}
}
and here is the part in which i'm using that card class:
Container(
height: 140,
child: ListView(
scrollDirection: Axis.horizontal,
children: <Widget>[
CardMain(
image: AssetImage('assets/heartbeat.png'),
title: "Hearbeat",
value: "66",
unit: "bpm",
color: Constants.lightGreen,
),
CardMain(
image: AssetImage('assets/blooddrop.png'),
title: "Blood Pressure",
value: "66/123",
unit: "mmHg",
color: Constants.lightYellow)
],
),
),
Each Card could extend to over 70 pixels and you limit your Container to 140. Nothing I see in your CardMain limits its height to 70. So either increase that height or limit your CardMain. Based on my math of 40+32+10 plus two rows of Text, you should have overflowed more than 8, but maybe your text was empty. Even empty text will take height...use
unit == '' ? Container() : Text(unit)
to get rid of empty text spacing.

How to prevent Row from taking all available width?

I have one problem with my CustomChip :
I need to wrap the card to fit the content only.
However, I have a second requirement: The long text should overflow fade.
When I fixed the second problem, this issue started to occur when I added Expanded to wrap the inner Row
I don't understand why the inner Row also seems to expand although its mainAxisSize is already set to min
Here is the code:
The screen:
import 'package:flutter/material.dart';
import 'package:app/common/custom_chip.dart';
class RowInsideExpanded extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Container(
decoration: BoxDecoration(
border: Border.all(
width: 1.0,
),
),
width: 200.0,
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
_buildChip('short'),
_buildChip('looooooooooooooooooooooongg'),
],
),
),
),
);
}
_buildChip(String s) {
return Row(
children: [
Container(
color: Colors.red,
width: 15,
height: 15,
),
Expanded(
child: CustomChip(
elevation: 0.0,
trailing: Container(
decoration: BoxDecoration(
color: Colors.grey,
shape: BoxShape.circle,
),
child: Icon(Icons.close),
),
onTap: () {},
height: 42.0,
backgroundColor: Colors.black12,
title: Padding(
padding: const EdgeInsets.symmetric(horizontal: 8.0),
child: Text(
s,
softWrap: false,
overflow: TextOverflow.fade,
style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 16.0),
),
),
),
),
],
);
}
}
And the CustomChip
import 'package:flutter/material.dart';
class CustomChip extends StatelessWidget {
final Widget leading;
final Widget trailing;
final Widget title;
final double height;
final double elevation;
final Color backgroundColor;
final VoidCallback onTap;
const CustomChip({
Key key,
this.leading,
this.trailing,
this.title,
this.backgroundColor,
this.height: 30.0,
this.elevation = 2.0,
this.onTap,
}) : super(key: key);
#override
Widget build(BuildContext context) {
return Card(
elevation: elevation,
color: backgroundColor,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(30.0),
),
child: InkWell(
onTap: onTap,
child: Container(
height: height,
child: Padding(
padding: const EdgeInsets.only(left: 5.0, right: 5.0),
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
leading ?? Container(),
SizedBox(
width: 5.0,
),
Flexible(
child: title,
fit: FlexFit.loose,
),
SizedBox(
width: 5.0,
),
trailing ?? Container(),
],
),
),
),
),
);
}
}
Look for "MainAxisSize" property and set to "MainAxisSize.min"
Instead of Expanded, just replace it with a Flexible that's because Expanded inherits Flexible but set the fit proprety to FlexFit.tight
When fit is FlexFit.tight, the box contraints for any Flex widget descendant of a Flexible will get the same box contraints. That's why your Row still expands even though you already set its MainAxisSize to min.
I changed your code to print the box contraints using a the LayoutBuilder widget.
Consider your code with Expanded:
import 'package:flutter/material.dart';
class RowInsideExpanded extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Container(
decoration: BoxDecoration(
border: Border.all(
width: 1.0,
),
),
width: 200.0,
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
_buildChip('short'),
SizedBox(
height: 5,
),
_buildChip('looooooooooooooooooooooongg'),
],
),
),
),
);
}
_buildChip(String s) {
return Row(
children: [
Container(
color: Colors.red,
width: 15,
height: 15,
),
Expanded(
child: LayoutBuilder(builder: (BuildContext context, BoxConstraints constraints) {
print("outter $constraints");
return Container(
color: Colors.greenAccent,
child: LayoutBuilder(builder: (BuildContext context, BoxConstraints constraints) {
print("inner $constraints");
return Row(
mainAxisSize: MainAxisSize.min, // this is ignored
children: <Widget>[
SizedBox(
width: 5.0,
),
Flexible(
fit: FlexFit.loose,
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 8.0),
child: Text(
s,
softWrap: false,
overflow: TextOverflow.fade,
style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 16.0),
),
),
),
SizedBox(
width: 5.0,
),
Container(
decoration: BoxDecoration(
color: Colors.grey,
shape: BoxShape.circle,
),
child: Icon(Icons.close),
),
],
);
}),
);
}),
),
],
);
}
}
It prints
I/flutter ( 7075): outter BoxConstraints(w=183.0, 0.0<=h<=Infinity)
I/flutter ( 7075): inner BoxConstraints(w=183.0, 0.0<=h<=Infinity)
(Look at the width in w, it constrained to be 183.0 for both outter and inner Row)
Now I changed the Expanded to Flexible and check the logs:
I/flutter ( 7075): outter BoxConstraints(0.0<=w<=183.0, 0.0<=h<=Infinity)
I/flutter ( 7075): inner BoxConstraints(0.0<=w<=183.0, 0.0<=h<=Infinity)
(Look at the width in w, it constrained to between zero and 183.0 for both outter and inner Row)
Now your widget is fixed:

How to limit draggable scrollable sheet to take height according to its child height in flutter?

and I also used a single child scroll view and column so that I can show my cards in that column of draggableScrollableSheet. But I want draggableScrollableSheet to take height dynamically instead of defining size. Like now I want to show only 2 to 3 cards and that is taking full screen. But I want it to take the minimum height of the screen. How can we achieve this?
I was struggling with this for a while, and then discovered that the correct way to achieve this is to use ClampingScrollPhysics as the physics parameter of the scroll view.
https://api.flutter.dev/flutter/widgets/ClampingScrollPhysics-class.html
I'm a week into Flutter but I found a solution to this. It might be substandard so correct me if I'm wrong.
So what I've done is create a variable called bsRatio for the bottom sheet. This is will be the height of the child view/widget (or bottom sheet content) divide by the height of the parent/screen. This ratio should be set to the maxChildSize and probably even the initialChildSize of your DraggableScrollableSheet.
So in your parent widget or Widget State class add something like this.
class ParentWidget extends StatefulWidget {
ParentWidget({Key? key}) : super(key: key);
#override
State<ParentWidget> createState() => _ParentWidgetState();
}
class _ParentWidgetState extends State<ParentWidget> {
var bsRatio = 0.4; // Set an initial ratio
#override
Widget build(BuildContext context) {
// The line below is used to get status bar height. Might not be required if you are not using the SafeArea
final statusBarHeight = MediaQuery.of(context).viewPadding.top;
// If you are not using SafeArea Widget you can skip subtracting status bar height from the Window height
final windowHeight = MediaQuery.of(context).size.height - statusBarHeight;
// This below is a callback function that will be passed to the child Widget of the DraggableScrollableSheet ->
childHeightSetter(childHeight) {
// setState rebuilds the UI with the new `bsRatio` value
setState(() {
// The new bottom sheet max height ratio is the height of the Child View/Widget divide by the screen height
bsRatio = childHeight / windowHeight;
});
}
return Scaffold(
backgroundColor: Colors.black12,
body: SafeArea(
child: Stack(
children: [
const SomeBackgroundView(),
DraggableScrollableSheet(
initialChildSize: bsRatio, // here you set the newly calculated ratio as the initial height of the Bottom Sheet
minChildSize: 0.2,
maxChildSize: bsRatio, // here you set the newly calculated ratio as the initial height of the Bottom Sheet
snap: true,
builder: (_, controller) {
return LayoutBuilder(builder: (_, box) {
// Added a container here to add some curved borders and decent looking shadows via the decoration property
return Container(
child: SingleChildScrollView(
controller: controller,
// The child view/widget `MyBottomSheet` below is the actual bottom sheet view/widget
child: MyBottomSheet(childHeightSetter: childHeightSetter),
),
decoration: const BoxDecoration(
boxShadow: [
BoxShadow(
color: Colors.grey,
blurRadius: 5.0,
spreadRadius: 2.0
)
],
borderRadius: BorderRadius.all(Radius.circular(20.0))
),
);
});
},
),
],
),
),
);
}
}
And this would be your child view/widget (also your BottomSheet view/widget)
class MyBottomSheet extends StatefulWidget {
// This below is the local callback variable. The `?` is because it may not be set if not required
final ValueSetter<double>? childHeightSetter;
const MyBottomSheet({Key? key, this.childHeightSetter}) : super(key: key);
#override
_MyBottomSheetState createState() => _MyBottomSheetState();
}
class _LoginBottomSheetState extends State<LoginBottomSheet> {
// bsKey is the key used to reference the Child widget we are trying to calculate the height of. Check the `Card` container below
GlobalKey bsKey = GlobalKey();
// this method will me used to get the height of the child content and passed to the callback function so it can be triggered and the ratio can be calculated and set in the parent widget
_getSizes() {
final RenderBox? renderBoxRed =
bsKey.currentContext?.findRenderObject() as RenderBox?;
final cardHeight = renderBoxRed?.size.height;
if (cardHeight != null)
super.widget.childHeightSetter?.call(cardHeight);
}
// This is the function to be called after the Child has been drawn
_afterLayout(_) {
_getSizes();
}
#override
void initState() {
super.initState();
// On initialising state pass the _afterLayout method as a callback to trigger after the child Widget is drawn
WidgetsBinding.instance?.addPostFrameCallback(_afterLayout);
}
#override
Widget build(BuildContext context) {
return Card(
key: bsKey, // This is the key mentioned above used to calculate it's height
color: Colors.white,
shadowColor: Colors.black,
elevation: 40.0,
margin: EdgeInsets.zero,
shape: const RoundedRectangleBorder(
borderRadius: BorderRadius.only(
topLeft: Radius.circular(20.0), topRight: Radius.circular(20.0))),
child: Column(
mainAxisAlignment: MainAxisAlignment.end,
children: [
// Random children for bottom sheet content
const SizedBox(height: 10.0),
Center(
child: Container(
child: const SizedBox(width: 40.0, height: 5.0),
decoration: BoxDecoration(
color: Colors.grey[400],
borderRadius: BorderRadius.circular(5.0)
),
),
),
const SizedBox(height: 10.0),
const AnotherBottomSheetContentView()
],
),
);
}
}
the initialChildSize is the height of your ScrollView before its actually scrolled, so that means you can actually decide what it would look like.
here is an example![the draggable scrollsheet here has initialChildSize: 0.1,maxChildSize: 1,minChildSize: 0.1,

How to make this screen responsive in Flutter?

I'm kinda confused with how responsive layouts are made with flutter can you guys point me to the right direction or where in my codes will be wrapped in Expanded widget?
I tried wrapping the containers with Extended but It keeps showing an error and I'm getting confused now. I'm still a beginner, to be honest. Thank you very much!
Also, when I searched I found out that I should avoid using hardcoded sizes most of the time. So I want to learn when to apply Extended widget in order to make my screen responsive.
my code is below:

Or
Use MediQuery() for getting the screen height and width i.e:-
Example:
#override
Widget build(BuildContext context) {
dynamic screenHeight = MediaQuery.of(context).size.height;
dynamic screenwidth = MediaQuery.of(context).size.width;
//use screenHeight and screenWidth variable for defining the height and
//width of the Widgets.
return Container(
height:screenHeight * .2, //It will take the 20% height of the screen
width: screenwidth * .5, //It will take the 50% width of the screen
//height: screenHeight, //It will take 100% height
child: Image(
image: AssetImage("assets/images/vlogo.png"),
);
}
You can make each screen responsive in flutter by just using MediaQuery or LayoutBuilder Concepts.
For your application, replace all your custom sizes like
width : MediaQuery.of(context).size.width * 0.1
height : MediaQuery.of(context).size.height * 0.3
MediaQuery gives you the sizes and orientation of the screen.
Even your padding, margin and other dimensions also should be calculated using MediaQuery to make it responsive.
Here, MediaQuery.of(context).size.width will give you the width of the current device screen and MediaQuery.of(context).size.height will give you the height of the current device screen.
Also, you can use LayoutBuilder Widget like,
LayoutBuilder(
builder: (context, constraints) {
if(constraints.maxWidth > 500) {
getLandscapeLayout();
} else {
getPortraitLayout();
}
},
)
LayoutBuilder is a widget which provides the dimensions of its parent so we can know how much space we have for the widget and can build it our child accordingly.
So these are two most powerful concepts are available in flutter to make your apps fully responsive.
