------------------------------ DO THIS IN YOUR APP SCREEN CODE !!!!!!!!!! :-------------------------------

import ImageCropper from 'polygonal-image-cropper/src/ImageCropper';


  const [crop, setCrop] = useState(false);
  const [useCameraInCropper, setUseCameraInCropper] = useState(false);
  const [initialImageForCropper, setInitialImageForCropper] = useState(null);




 TO OPEN THE GALERIE BEFORE THE CROPPER YOU NEED TO ADD THIS IN YOU APP SCREEN CODE TOO :
 
 const handlePickAndCropImage = async () => {
  try {
    const result = await ImagePicker.launchImageLibraryAsync({
      mediaTypes: ImagePicker.MediaTypeOptions.Images,
      allowsEditing: false,
      quality: 1,
    });

    if (!result.canceled && result.assets.length > 0) {
      setInitialImageForCropper(result.assets[0].uri);
      setUseCameraInCropper(false); // sécurité
      setCrop(true);
    }
  } catch (error) {
    console.log("Erreur lors du choix de l'image :", error);
  }
}; 




YOUR CAMERA AND GALERY Bottons :


        <TouchableOpacity
              style={styles.buttonOutline}
              onPress={() => {
                setUseCameraInCropper(true);
                setCrop(true);
              }}
            >

            <TouchableOpacity
