Aspect of undefined in diferent file React Native - ios

Question

Iam trying to access camera but i get this error. I try to do all tutorial that people have show in other pages to make it work but i didn't have the same loki.
I enter at this file: \myproject\node_modules\lottie-ios\Example-Swift\Pods\Target Support Files\lottie-ios\Info.plist and add this:
<key>NSCameraUsageDescription</key>
<string>Feetit Would you like to access Camera</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Feetit Would you like to access Photos</string>
Before that I install this:
npm install react-native-camera --save
npm install react-native link react-native-camera
After that I try this code for make Camera works:
import React, {Component} from 'react';
import Camera from 'react-native-camera';
import {View, TouchableHighlight, Text, StyleSheet} from 'react-native';
export default class CameraAcess extends Component {
takePicture() {
const options = {};
//options.location = ...
this.camera.capture({metadata: options})
.then((data) => console.log(data))
.catch(err => console.error(err));
}
onBarCodeRead(e) {
console.log(
"Barcode Found!", "Type: " + e.type + "\nData: " + e.data
);
}
render() {
return (
<View style={styles.container}>
<Camera
ref={(cam) => {
this.camera = cam;
}}
onBarCodeRead={this.onBarCodeRead.bind(this)}
style={styles.preview}>
<TouchableHighlight style={styles.capture} onPress={this.takePicture.bind(this)}>[CAPTURE]
<Text>Click me</Text>
</TouchableHighlight>
</Camera>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'row',
},
preview: {
flex: 1,
justifyContent: 'flex-end',
alignItems: 'center'
},
capture: {
flex: 0,
backgroundColor: '#fff',
borderRadius: 5,
color: '#000',
padding: 10,
margin: 40
}
});
I get this ERROR 'Can not read proprety 'Aspect' of undefined. The file of this error is other one, is Camera.js. Could Someone please tell me what i have to do to make it Work?

Answer 1

I looked over the docs and did not see this variable on the camera required however i did see in an example I built that I set this variable on the Camera. See if this helps as it may not start with a default value.
aspect={Camera.constants.Aspect.fill}
Change to your preference.

If you are facing this problem in iOS then
Remove the previously-installed react-native-camera pod.
$ cd ios
$ rm -rf Pods/
$ pod install
And then manually link
as mentioned in librarary readme
Plese check the permissions also which are required for camera.
