The error message "Cannot read property 'camera' of undefined" appeared when trying to access '_this.camera'

I'm attempting to display the camera feed from the front-facing camera within a <View> component, but I keep encountering this persistent error. Despite trying to reinstall react-native-camera and utilizing expo-camera, I am running out of solutions. Code:

import {RNCamera, Camera} from 'react-native-camera'
import { View,Text,Screen,Image  } from 'react-native';
import Button from 'apsl-react-native-button';
import React from 'react';

export default function Meeting ({navigation}){
    return (
        <View style={{
            backgroundColor: "#fff",
            flex:1,
            alignItems: 'center',
            justifyContent: 'center'
        }}>
        <View
        style={{
            position: 'relative',
            left:0,
            top:-15,
            width:1080,
            height:480,
            backgroundColor: '#c4c4c4'
        }}
        >
        <RNCamera
          style={{ flex: 1, alignItems: 'center' }}
          captureAudio={false}
          ref={ref => {
            this.camera = this.camera.bind(this )
            this.camera = ref
          }}
        />
            
        </View>


        </View>
    )
}
