Hi!
I'm new with react native so this could be my mistake but neither the sample code does not work for me, the canvas remain empty. So I try this for Windows:
import { useEffect, useRef } from 'react'; import {Text, TextInput, StyleSheet, SafeAreaView } from 'react-native'; import Canvas from 'react-native-canvas'; function Canv (prop) { const canvasRef = useRef(null); useEffect(() => { if (canvasRef.current) { const canvas = canvasRef.current; const context = canvas.getContext('2d'); context.fillStyle = 'red'; context.fillText ("Test", 10, 10); context.fillRect(0, 0, 100, 100); } }, [canvasRef, prop.text]); return ( <SafeAreaView style={{ flex: 1 }}> <Text>{prop.text}</Text> <Canvas ref={canvasRef} style={[{ width: '100%', height: '100%', backgroundColor: 'transparent' }]} /> </SafeAreaView> ) } export default Canv;
If I debug a little a got this error message, but I don't know what it means or why I got this: Error at Canvas._callee$ (http://localhost:8081/index.bundle?platform=windows&dev=true&hot=false&inlineSourceMap=true:98642:24) at tryCatch (http://localhost:8081/index.bundle?platform=windows&dev=true&hot=false&inlineSourceMap=true:46451:19) at Generator.

Any Idea? It would be great if worked it. Thank you!
