This is ScreenShot

My suggestion would be using CustomPaint instead of CustomClipper<Path>.
CustomPaint
class SkewCut extends CustomPainter {
#override
void paint(Canvas canvas, Size size) {
var paint = Paint();
paint.color = Colors.purpleAccent;
paint.style = PaintingStyle.fill;
var pathUp = Path();
pathUp.moveTo(0, size.height * 0.1033);
pathUp.quadraticBezierTo(size.width * 0.25, size.height * 0.145,
size.width * 0.5, size.height * 0.1033);
pathUp.quadraticBezierTo(size.width * 0.75, size.height * 0.0750,
size.width * 1.0, size.height * 0.1033);
pathUp.lineTo(size.width, 0);
pathUp.lineTo(0, 0);
canvas.drawPath(pathUp, paint);
}
#override
bool shouldRepaint(CustomPainter oldDelegate) {
return true;
}
}
I have just replaced your CustomClipper with CustomPainter.
Usage
#override
Widget build(BuildContext context) {
return Container(
color: Colors.white,
child: CustomPaint(
painter: SkewCut(),
child: <<YOUR CHILD WIDGET>>,
),
);
}

While there are many ways to do this but personally I use the following visual editor to have some generated code and then tweak it based on requirements.

This saves me a lot of time and effort.

Flutter border around container with text in the middle (divider?)

I try to create a border around a container, that is not that difficult ofcourse, but i need also a text IN the border with space around it. Like horizontal divder but i need a complete border.
Attached what i like to achieve.
Any one who can help me how to approach this?
Thanks!
Tried to use the horizontal and vertical divider packages, but then the border is not in full.
You can use CustomPainter like this:
class CustomDraw extends CustomPainter {
late Paint painter;
late double radius;
late double textWidth;
CustomDraw(Color color, this.textWidth, {this.radius = 0}) {
painter = Paint()
..style = PaintingStyle.stroke
..strokeWidth = 2
..color = color;
}
#override
void paint(Canvas canvas, Size size) {
var path = Path();
path.moveTo(size.width - ((size.width - textWidth) / 2), 0);
path.lineTo(size.width - radius, 0);
path.cubicTo(size.width - radius, 0, size.width, 0, size.width, radius);
path.lineTo(size.width, size.height - radius);
path.cubicTo(size.width, size.height - radius, size.width, size.height,
size.width - radius, size.height);
path.lineTo(radius, size.height);
path.cubicTo(radius, size.height, 0, size.height, 0, size.height - radius);
path.lineTo(0, radius);
path.cubicTo(0, radius, 0, 0, radius, 0);
path.lineTo(((size.width - textWidth) / 2), 0);
canvas.drawPath(path, painter);
}
#override
bool shouldRepaint(covariant CustomPainter oldDelegate) => false;
}
and this widget:
class CustomTitleWidget extends StatefulWidget {
final double height;
final double width;
final double? radius;
final String title;
const CustomTitleWidget(
{Key? key,
required this.height,
required this.width,
required this.title,
this.radius})
: super(key: key);
#override
State<CustomTitleWidget> createState() => _CustomTitleWidgetState();
}
class _CustomTitleWidgetState extends State<CustomTitleWidget> {
GlobalKey textKey = GlobalKey();
double textHeight = 0.0;
double textWidth = 0.0;
#override
void initState() {
super.initState();
WidgetsBinding.instance.addPostFrameCallback((_) {
setState(() {
final textKeyContext = textKey.currentContext;
if (textKeyContext != null) {
final box = textKeyContext.findRenderObject() as RenderBox;
textHeight = box.size.height;
textWidth = box.size.width;
}
});
});
}
#override
Widget build(BuildContext context) {
return Stack(
clipBehavior: Clip.none,
alignment: Alignment.topCenter,
children: [
CustomPaint(
child: Container(
height: widget.height,
width: widget.width,
),
painter: CustomDraw(
Colors.red,
textWidth,
radius: widget.radius ?? 0,
),
),
Positioned(
top: -textHeight / 2,
child: Padding(
key: textKey,
padding: EdgeInsets.symmetric(horizontal: 8.0),
child: Text(
widget.title,
),
),
)
],
);
}
}
use like this:
CustomTitleWidget(
height: 200,
width: double.infinity,
title: 'asdasdasdasdasd',
radius: 16),
#Maenda, We can implement such kind of structure using Stack, take one container with a border & put the other container over the first one.
Here is an example:
Stack(
children: [
Positioned(
top: 12,
left: 0,
right: 0,
child: Container(
height: 120,
width: MediaQuery.of(context).size.width,
margin: EdgeInsets.symmetric(horizontal: 10, vertical: 10),
padding: EdgeInsets.all(8),
decoration: BoxDecoration(
color: Colors.green,
border: Border.all(width: 1.2),
borderRadius: BorderRadius.circular(3)),
)),
Container(
margin: EdgeInsets.symmetric(
horizontal: 21,
),
child: Column(
children: [
Container(
width: 100,
margin: EdgeInsets.only(top: 12, bottom: 5),
alignment: Alignment.center,
color: Colors.blue,
child: Text(
"Any Text",
style: TextStyle(
fontSize: 16,
fontWeight: FontWeight.w500,
),
),
),
Text(
"Nature, in the broadest sense, is the physical world or universe. Nature can refer to the phenomena of the physical world, and also to life in general.",
textAlign: TextAlign.center,
),
SizedBox(
height: 8,
)
],
),
),
],
);
Hope this works! You can customize as per the design.

How to fit a GridView.Builder inside a ClipPath Container in Flutter

what I want to achieve is centring the whole grid view inside the blue background, and to be able to scroll it.
The screenshot only shows the container I'm editing and not the whole page.

what i am trying to achieve
my result. the shape is not perfect.
thanks
At first I wanted to describe you the ways you can achieve the shape you want and so on...
But got carried away with this fun programming challenge and ended up creating an actual widget :)
It depends on the font_awesome_flutter package, so don't forget to install it (for the heart icon). font_awesome_flutter
So the widget's source code is:
import 'package:flutter/material.dart';
import 'dart:math' as math;
import 'package:font_awesome_flutter/font_awesome_flutter.dart';
extension ToRadians on int {
double get toRadians => this * (math.pi / 180.0);
}
enum _ButtonType { like, dislike }
class LikeOrNot extends StatelessWidget {
final VoidCallback onLike;
final VoidCallback onDislike;
// Percents from total widget width, default - 2%
final _gapSizeRatio = 0.02;
final _likeIconColor = const Color(0xffb85076);

It's dynamic, the buttons are built-in. You get 2 options to work with - onDislike() and onLike() callbacks.
An example using different sizes.
class MyHomePage extends StatelessWidget {
const MyHomePage({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return DecoratedBox(
decoration: const BoxDecoration(
gradient: LinearGradient(
colors: [Color(0xffc0496f), Color(0xffdb6b59)],
begin: Alignment.centerLeft,
end: Alignment.centerRight,
),
),
child: Scaffold(
backgroundColor: Colors.transparent,
appBar: AppBar(
title: const Text('Test'),
backgroundColor: Colors.transparent,
elevation: 0,
),
body: Container(
width: double.infinity,
padding: const EdgeInsets.all(20.0),
child: Column(
children: [
for (final size in List.generate(5, (index) => index++))
FractionallySizedBox(
widthFactor: 1.0 - size * 0.2,
child: LikeOrNot(
onLike: () {},
onDislike: () {},
),
),
],
),
),
),
);
}
}
There's a _gapSize parameter which is the gap between two circles. The one you need is already inside (2% default) but you can get some cool other variations by changing it. For example, here's a gap of 20% total width:

Draw Bezier curve with rectangle in Flutter

I'm starting with Flutter and have to design a UI that looks like
But with icon button at the center of the Bezier curve.
What I tried is
class HeaderPainter extends CustomPainter {
HeaderPainter({
#required this.color,
#required this.avatarRadius
});
final Color color;
final double avatarRadius;
#override
void paint(Canvas canvas, Size size) {
final shapeBounds = Rect.fromLTRB(0, 0, size.width, size.height - avatarRadius);
final centerAvatar = Offset(shapeBounds.center.dx, shapeBounds.bottom);
final avatarBounds = Rect.fromCircle(center: centerAvatar, radius: avatarRadius).inflate(3);
_drawBackground(canvas, shapeBounds, avatarBounds);
}
#override
bool shouldRepaint(HeaderPainter oldDelegate) {
return color != oldDelegate.color;
}
void _drawBackground(Canvas canvas, Rect shapeBounds, Rect avatarBounds) {
final paint = Paint()..color = color;
final backgroundPath = Path()
..moveTo(shapeBounds.left, shapeBounds.top)
..lineTo(shapeBounds.bottomLeft.dx, shapeBounds.bottomLeft.dy)
..arcTo(avatarBounds, -pi, pi, false)
..lineTo(shapeBounds.bottomRight.dx, shapeBounds.bottomRight.dy)
..lineTo(shapeBounds.topRight.dx, shapeBounds.topRight.dy)
..lineTo(0.0, shapeBounds.height - 100)
..quadraticBezierTo(
shapeBounds.width / 4, shapeBounds.height,
shapeBounds.width / 2, shapeBounds.height
)
..quadraticBezierTo(
shapeBounds.width - shapeBounds.width / 4, shapeBounds.height,
shapeBounds.width, shapeBounds.height - 100
)
..lineTo(shapeBounds.width, 0.0)
..close();
canvas.drawPath(backgroundPath, paint);
}
}
And the outcome is
How can I get the bezier curve with the rectangle?
Edit 2: The HeaderPainter is used like
#override
Widget build(BuildContext context) {
return Stack(
children: <Widget>[
Container(
child: CustomPaint(
size: Size.fromHeight(400.0),
painter: HeaderPainter(
color: Colors.red,
avatarRadius: avatarRadius
),
),
),
Positioned(
left: 0,
right: 0,
bottom: titleBottomMargin,
child: Column(
children: <Widget>[
Text('Hello World', style: TextStyle(fontWeight: FontWeight.bold),),
],
),
),
Align(
alignment: Alignment.bottomCenter,
child: CircleAvatar(
radius: avatarRadius,
backgroundColor: Colors.green,
child: IconButton(icon: Icon(Icons.message), onPressed: _onAddMessageButtonClick,),
),
)
],
);
}
Got it solved using ClipPath and CustomClipper.
The updated build() method is
#override
Widget build(BuildContext context) {
return Stack(
children: <Widget>[
Container(
child: ClipPath(
clipper: HeaderClipper(avatarRadius: avatarRadius),
child: CustomPaint(
size: Size.fromHeight(400.0),
painter: HeaderPainter(
color: Colors.green,
avatarRadius: avatarRadius
),
),
),
),
...
and HeaderClipper
class HeaderClipper extends CustomClipper<Path> {
HeaderClipper({
#required this.avatarRadius
});
final avatarRadius;
#override
getClip(Size size) {
final path = Path()
..lineTo(0.0, size.height - 100)
..quadraticBezierTo(
size.width / 4, (size.height - avatarRadius),
size.width / 2, (size.height - avatarRadius)
)
..quadraticBezierTo(
size.width - (size.width / 4), (size.height - avatarRadius),
size.width, size.height - 100
)
..lineTo(size.width, 0.0)
..close();
return path;
}
#override
bool shouldReclip(CustomClipper oldClipper) {
return false;
}
}
The final output is

Flutter : Achieved Sliverappbar Shape

I'm found some Appbar design in Dribble https://dribbble.com/shots/9175650-Beauty-Salon-App/attachments/1218583?mode=media , I try to create same like that but i confused get border radius each other side.
Trial 1 Without Background :
Trial 2 With Scaffold Background Color Blue
Trial 3 With background Color Deep Orange
How can i achieved appbar design like the link ?
Source Code
import 'package:flutter/material.dart';
import 'package:flutter_iconpicker/flutter_iconpicker.dart';
class TestingScreen extends StatelessWidget {
static const routeName = "/testing-screen";
#override
Widget build(BuildContext context) {
var mediaQuery = MediaQuery.of(context);
return Scaffold(
body: CustomScrollView(
slivers: <Widget>[
SliverAppBar(
expandedHeight: mediaQuery.size.height / 4,
backgroundColor: Colors.deepOrange,
shape: RoundedRectangleBorder(
borderRadius:
BorderRadius.only(bottomRight: Radius.circular(80))),
),
SliverList(
delegate: SliverChildListDelegate(
[
Container(
height: mediaQuery.size.height,
decoration: BoxDecoration(
color: Colors.blue,
borderRadius:
BorderRadius.only(topLeft: Radius.circular(80))),
child: Center(child: Text('data')),
)
],
),
)
],
),
);
}
}
You can actually use CustomClipper to do this, with a method of Path quadraticBezierTo:
class MyHomePage extends StatelessWidget {
#override
Widget build(BuildContext context) {
