How to implement Processingview in React Native Expo? - react-native

Question

Here I have implemented ProcessingView in Expo App. But I am getting this error "Check the render method of ProcessingView.". I am not able to find the solution. If anyone has idea then please guide me.
Here I have also attached the image of the screen
import React from 'react';
import { ProcessingView } from 'expo-processing';
export default class App extends React.Component {
render() {
return (
<ProcessingView style={{ flex: 1 }} sketch={this._sketch} />
);
}
_sketch = (p) => {
p.setup = () => {
p.strokeWeight(7);
}
const harom = (ax, ay, bx, by, level, ratio) => {
if (level <= 0) {
return;
}
const vx = bx - ax;
const vy = by - ay;
const nx = p.cos(p.PI / 3) * vx - p.sin(p.PI / 3) * vy;
const ny = p.sin(p.PI / 3) * vx + p.cos(p.PI / 3) * vy;
const cx = ax + nx;
const cy = ay + ny;
p.line(ax, ay, bx, by);
p.line(ax, ay, cx, cy);
p.line(cx, cy, bx, by);
harom(
ax * ratio + cx * (1 - ratio),
ay * ratio + cy * (1 - ratio),
ax * (1 - ratio) + bx * ratio,
ay * (1 - ratio) + by * ratio,
level - 1,
ratio);
}
p.draw = () => {
p.background(240);
harom(
p.width - 142, p.height - 142, 142, p.height - 142, 6,
(p.sin(0.0005 * Date.now() % (2 * p.PI)) + 1) / 2);
}
}
}
