Hello im new in react native and i just building my first react native project with camera without expo.
I installed it with npm install react-native-camera and then linked it with react-native link react-native-camera.
The camera run successfuly, but when i triggered the snap button it got error like this....
{ [TypeError: camera.takePictureAsync is not a function. (In 'camera.takePictureAsync(options)', 'camera.takePictureAsync' is undefined)] │ line: 131480, │ column: 72, └ sourceURL: 'http://localhost:8081/index.bundle?platform=android&dev=true&minify=false' }
Here is my code looks like...
import React, { useRef } from 'react'
import { View, Text, StyleSheet, TouchableOpacity } from 'react-native'
import { RNCamera } from 'react-native-camera'
function PlayWithCamera() {
const camera = useRef(null)
const takePicture = async () => {
try {
const options = { quality: 0.5, base64: true };
const data = await camera.takePictureAsync(options);
console.log(data.uri, '<<<<<<<<<<<<<<<<<<<<<');
} catch (error) {
console.log(error, "ERROR <<<<<<<<<<<<<")
}
};
return (
<View style={styles.container}><RNCamera
ref={camera}
style={styles.preview}

console.log(barcodes)
}}

)
}
const styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'column',
backgroundColor: 'black',
},
preview: {
flex: 1,
justifyContent: 'flex-end',
alignItems: 'center',
},
capture: {
flex: 0,
backgroundColor: '#fff',
borderRadius: 5,
padding: 15,
paddingHorizontal: 20,
alignSelf: 'center',
margin: 20,
},
})
export default PlayWithCameraUPDATE (18.48):
I tried using class component like in react-native-camera documentation did, and it finally works. But i still curious how to make it works in function component?
