Key "uri" in the image picker result is deprecated and will be removed in SDK 48, you can access selected assets through the "assets" array instead – React native

const selectImage = async () =>{
        try {
            const result = await ImagePicker.launchImageLibraryAsync({
                mediaTypes: ImagePicker.MediaTypeOptions.Images,
                allowsEditing: true,
                aspect: [4, 3],
                quality: 0.5
            });
            
            if(!result.canceled){
               setImage(result.uri)
               saveToFile();
            }else Alert.alert('Delete', 'Are you sure you want to delte the image', [
                {text:"Yes", onPress:()=> setImage(null)},{text:"No"} ])
            
        } catch (error) {
            console.log("error reading an image")
            
        }
    }
