Polygon clipper in Flutter

In this tutorial, you will learn how to implement a flutter polygon clipper. Polygon clipper can be used to create different shaped cards. After finishing this tutorial you will know how to clip a widget into polygons with sides greater than 3. You will learn how to create a triangle container, pentagon container, hexagonal container, octagonal container and so on. The implementation is quite simple as there is already a package available in Dart Pub called polygon_clipper . We just need to install the package and customize its attributes.


The first step is to add the package polygon_clipper to pubspec.yaml as shown below. Run flutter pub get to install the package.


Import the polygon_clipper package at the top of the dart file.


In the above example, the code shows how to create a polygon clipper. The attributes which we can customize are:

  1. sides - The number of sides of the polygon. In the above example we have given the value of sides as 5. This will give us a pentagonal card. To make a hexagonal card just make the value of sides 6.
  2. borderRadius - Border radius can be 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.
  3. rotate - You can specify the angle of rotation in degrees. For example, we have rotated the polygon 90 degress in the above code
  4. boxShadows - You can also customize the box shadow to change the perceived elevation of the card.

Hope you guys try this in your next app UI. Good Luck!
