React Native Figma Squircle

Figma-flavored squircles for React Native

Disclaimer

This library is not an official product from the Figma team and does not guarantee to produce the same results as you would get in Figma.

What is this?

Figma has a great feature called corner smoothing, allowing you to create rounded shapes with a seamless continuous curve (squircles).

This library helps you bring those squircles to your React Native apps.

Installation

Install react-native-svg

Then install this library:

yarn add react-native-figma-squircle

or

npm install react-native-figma-squircle

Usage

A SquircleView can be used just like a normal View, except the background is rendered separately from the view background. So to change how it looks, you'll have to use the squircleParams prop instead of the style prop.

import { SquircleView } from 'react-native-figma-squircle'

function PinkSquircle() {
  return (
    <SquircleView
      style={{ width: 200, height: 200 }}
      squircleParams={{
        cornerSmoothing: 0.7,
        cornerRadius: 30,
        fillColor: 'pink',
      }}
    />
  )
}

You can also use it with MaskedView to apply the squircle shape to an Image.

import MaskedView from '@react-native-community/masked-view'

function ProfilePicture() {
  return (
    <MaskedView
      style={styles.profilePicture}
      maskElement={
        <SquircleView
          style={StyleSheet.absoluteFill}
          squircleParams={{
            cornerRadius: 30,
            cornerSmoothing: 0.7,
            fillColor: 'pink',
          }}
        />
      }
    >
      <Image style={StyleSheet.absoluteFill} source={{ uri: 'https://...' }} />
    </MaskedView>
  )
}
