Possible Unhandled Promise Rejection (id: 0): TypeError: undefined is not an object (evaluating '_this.props.navigation.navigate') - react-native

Question

I'm trying to display an image I have captured using expo-camera, from the camera component I'm trying to navigate to a new file which will display the image but after I took the image it won't navigate to the new page.
I tried importing the file and then navigate it but it still won't work and give me the warning instead.
This is the code where I tried to navigate to the new file.
export default class CameraExample extends React.Component {
state = {
hasCameraPermission: null,
type: Camera.Constants.Type.back,
};
async componentDidMount() {
const { status } = await Permissions.askAsync(Permissions.CAMERA);
this.setState({ hasCameraPermission: status === 'granted' });
}
snap = async() => {
if(this.camera) {
console.log('Taking photo');
const options = {quality: 1, base64: true, fixOrientation: true, exif: true};
const photo = await this.camera.takePictureAsync(options);
this.props.navigation.navigate("Show", {photouri: photo.uri})
}
}
render() {
const { hasCameraPermission } = this.state;
if (hasCameraPermission === null) {
return <View />;
} else if (hasCameraPermission === false) {
return <Text>No access to camera</Text>;
} else {
return (
<View style={{ flex: 1 }}>
<Camera style={{ flex: 1 }} type={this.state.type}
ref = {ref => {
this.camera = ref;
}}
>
<View
style={{
flex: 1,
backgroundColor: 'transparent',
flexDirection: 'row',
}}>
<TouchableOpacity onPress={this.snap.bind(this)}>
<Ionicons
name = "md-camera"
color = "white"
size = {30}
/>
</TouchableOpacity>
<TouchableOpacity
style={{
flex: 0.1,
alignSelf: 'flex-end',
alignItems: 'center',
}}
onPress={() => {
this.setState({
type:
this.state.type === Camera.Constants.Type.back
? Camera.Constants.Type.front
: Camera.Constants.Type.back,
});
}}>
<Ionicons
name = "md-reverse-camera"
color = "white"
size = {30}
/>
</TouchableOpacity>
</View>
</Camera>
</View>
);
}
}
}
And this is the code where I try to display the image.
export default class ShowImages extends React.Component{
render(){
console.log('OK')
const { navigation } = this.props;
const paramm = navigation.getParam('photouri');
return(
<Content>
<View>
<Text>
paramm: {JSON.stringify(paramm)}
</Text>
<Image style={{height: 700, width: 850, alignSelf: "center"}}
source={{uri: this.props.navigation.state.paramm.photouri}}
resizeMode="contain"/>
</View>
</Content>
)
}
}
I expect it to navigate to the new page and display the captured
image but it gave me the warning. I can't seem to find what is wrong with my code. Can anyone suggest what I should do? Thank you.

change this
<TouchableOpacity onPress={this.snap.bind(this)}> => <TouchableOpacity onPress={this.snap}>
Put it in the status value and pass it on.
export default class ShowImages extends React.Component{
constructor(props) {
super(props);
this.state = {
paramm: this.props.navigation.state.params.photouri
};
}
...
<Image style={{height: 700, width: 850, alignSelf: "center"}}
source={{uri: this.state.paramm }}
resizeMode="contain"/>
