Black screen

[ganascimento]

I am having black screen problem, I already made several configurations however I did not have any progress. The code below is what I am currently using, could you help me:

import React from 'react'
import { PermissionsAndroid, View } from 'react-native'
import DocumentScanner from 'react-native-documentscanner-android'

export default class ScanDoc extends React.Component {

componentDidMount() {
    async function requestCameraPermission() {
        console.log("requestCameraPermission")
        try {
            const granted = await PermissionsAndroid.request(
                PermissionsAndroid.PERMISSIONS.CAMERA,
                {
                    'title': 'Cool Photo App Camera Permission',
                    'message': 'Cool Photo App needs access to your camera ' +
                    'so you can take awesome pictures.'
                }
            )
            if (granted === PermissionsAndroid.RESULTS.GRANTED) {
                console.log("You can STORE the camera")
            } else {
                console.log("storage permission denied")
            }
        }catch(e){
            console.log(e)
        }
        try {
            const granted = await PermissionsAndroid.request(
                PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
                {
                    'title': 'Cool Photo App Camera Permission',
                    'message': 'Cool Photo App needs access to your camera ' +
                    'so you can take awesome pictures.'
                }
            )
            if (granted === PermissionsAndroid.RESULTS.GRANTED) {
                console.log("You can write storage")
            } else {
                console.log("storage permission denied")
            }
        }catch(e){
            console.log(e)
        }
    }
    requestCameraPermission();
}

render(){
    return (
        <View style={{flex: 1}}>
            <DocumentScanner style={{flex: 1, backgroundColor: 'transparent', width: '100%', height: '100%',}}
                onPictureTaken={data => {
                    console.log(data.path);
                }}
                enableTorch={false}
                detectionCountBeforeCapture={5}/>
        </View>
    )
}

}

Please could you share with me a project where it works correctly for me to see where the problem is, as I still have the black screen.
