Explore Polygon Clipper In Flutter
It can be utilized by Clipper to clip the widget into any ideal shape. In Flutter, it very well may be done effectively because of built-in clippers like ClipOval, ClipRect, ClipRRect, and ClipPath. To accomplish this polygon shape you want to characterize what is the way which you want to clip to make your UI marvelous.
In this article, we will Explore Polygon Clipper In Flutter. We will implement a polygon clipper demo program and create a different polygon shape using the polygon_clipper package in your flutter applications.
polygon_clipper | Flutter Package
A Flutter plugin to create views using regular polygon shapes (e.g. Pentagons and Hexagons).pub.dev

Introduction:
Polygon clippers can be utilized to make distinctively shaped cards. After completing this article you will realize how to clip a widget into polygons with sides more noteworthy than three. You will figure out how to make a pentagonal shape, hexagonal shape, octagonal shape, etc.
Demo Module :
This demo video shows how to create a polygon clipper in a flutter. It shows how the polygon clipper will work using the polygon_clipper package in your flutter applications. It shows a pentagonal, hexagonal, octagonal shape and inside a network image using Polygon clippers. It will be shown on your device.
Constructor:
To utilize ClipPolygon, you need to call the constructor underneath:
ClipPolygon(
{@required this.child,
@required this.sides,
this.rotate: 0.0,
this.borderRadius: 0.0,
this.boxShadows: const []
}
);
In the above Constructor, all fields marked with @required must not be empty.
Attributes:
There are some attributes of ClipPolygon are:
- > sides — This attribute is used to the number of sides of the polygon. In the above example, we have given the value of sides as 5 means pentagonal shape. To make a hexagonal shape just make the value of sides 6 and also make a different shape according to sides.
- > borderRadius — This attribute is used to smoothen out the pointy edges. You can change the value to improve the aesthetics or accordance with the general theme you follow for your app.
- > rotate — This attribute is used so you can specify the angle of rotation in degrees. For example, we have rotated the polygon 90 and 70 degrees in the above code
- > boxShadows — This attribute is used you can also customize the box-shadow to change the perceived elevation of the card.
- > child — This attribute is used to the widget can only have one child. To layout multiple children, let this widget’s child be a widget such as Row, Column, or Stack, which have a children property, and then provide the children to that widget.
Implementation:
Step 1: Add the dependencies
Add dependencies to pubspec — yaml file.
dependencies:
flutter:
sdk: flutter
polygon_clipper: ^1.0.2
Step 2: Import
import 'package:polygon_clipper/polygon_clipper.dart';
Step 3: Run flutter packages get in the root directory of your app.
How to implement code in dart file :
You need to implement it in your code respectively:
Create a new dart file called main.dart inside the lib folder.
We will create three shapes of polygon clippers are pentagonal, hexagonal, and octagonal shapes. We will deeply discuss the below in code.
Container(
padding: EdgeInsets.all(30.0),
child: ClipPolygon(
sides: 5,
borderRadius: 5.0,
rotate: 70.0,
boxShadows: [
PolygonBoxShadow(color: Colors.black, elevation: 7.0),
PolygonBoxShadow(color: Colors.blue, elevation: 5.0)
],
child: Container(
child: Image.network(

fit: BoxFit.cover,
),
),
)),
We will make a container widget. In this widget, we will add ClipPolygon() widget. Inside, we will add sides was five for pentagonal shape, borderRadius was five, rotate was 70 degrees and boxShadows. It’s child property, we will add Container and it’s child property, we will add an image network. When we run the application, we ought to get the screen’s output like the underneath screen capture.
Next, we will create the same method as above. In ClipPolygon(), sides were six for hexagonal shape, rotate was 90 degrees, and boxShadows color for shadow/elevation of the card.
Container(
padding: EdgeInsets.all(30.0),
child: ClipPolygon(
sides: 6,
borderRadius: 5.0,
rotate: 90.0,
boxShadows: [
PolygonBoxShadow(color: Colors.greenAccent, elevation: 4.0),
PolygonBoxShadow(color: Colors.green, elevation: 5.0)
],
child: Container(
color: Colors.black,
child: Image.network(

fit: BoxFit.cover,
),
),
)),
When we run the application, we ought to get the screen’s output like the underneath screen capture.
Next, we will create the same method as above. In ClipPolygon(), sides were eighth for octagonal shape, rotate was 90 degrees, and boxShadows color for shadow/elevation of the card.
Container(
padding: EdgeInsets.all(30.0),
child: ClipPolygon(
sides: 8,
borderRadius: 5.0,
rotate: 90.0,
boxShadows: [
PolygonBoxShadow(color: Colors.black, elevation: 1.0),
PolygonBoxShadow(color: Colors.grey, elevation: 5.0)
],
child: Container(
color: Colors.black,
child: Image.network(

fit: BoxFit.cover,
),
),
)),
When we run the application, we ought to get the screen’s output like the underneath screen capture.

Conclusion:
In the article, I have explained the basic structure of the Polygon Clipper in a flutter; you can modify this code according to your choice. This was a small introduction to Polygon Clipper On User Interaction from my side, and it’s working using Flutter.
I hope this blog will provide you with sufficient information on Trying up the Polygon Clipper in your flutter projects. We will show you what the Introduction is?. Show constructor and attributes of the Polygon Clipper. Make a demo program for working Polygon Clipper, and it shows a pentagonal, hexagonal, octagonal shape and inside a network image using Polygon clippers in your flutter application. So please try it.
