Wen i delete my document from Firestore the corresponding image still remain in Storage

I am new in flutter, I am facing a problem which is how to delete Firestore photos.

I have created a Subcollection where I am storing my products details, this product also contains an image that is stored in Firebase Storage. If delete my product, like I have 10 products but I want to delete a specific product, when I am pressing the delete button it is deleting my products which is a document but it does not delete the corresponding image from Firebase Storage.

I have tried some way but it's not working, it's just deleting my Cloud Firestore document but the photo remains in Firebase Storage.

I am using the image URL to show the photo. I want that when I click on my delete Button it also delete the corresponding image from Firebase Storage. so I am using this to delete my Cloud Firestore document.

TextButton(
  onPressed: () async {
    await FirebaseFirestore.instance
        .collection('users')
        .doc(LoginUser!.uid)
        .collection('products')
        .doc(document.id)
        .delete()
        .then((value) async {
      //await FirebaseStorage.instance.ref().child('productImage').child('productImageUrl').delete();
      
      
      print(
          'Product Deleted But image is still there in Storage Folder');
    });
  },
  child: Text('Delete')),

I am using This code to save my image Url in Cloud Firestore

final productImgRef = FirebaseStorage.instance
    .ref()
    .child('productImage')
    .child(FirebaseUser.uid +time +'.jpg');
await productImgRef.putFile(pickImageFile!);
var productImageUrl = await productImgRef.getDownloadURL();

await FirebaseFirestore.instance
    .collection('users')
    .doc(FirebaseUser.uid)
    .collection('products')
    .add({
  'productName': _productName,
  'productDes': _productDes,
  'bidPrice': _bidPrice,
  'auctionDate': _auctionDate,
  'submitBy': userName,
  'productImageUrl': productImageUrl,
});

Assuming that this commented out line is what you tried:

await FirebaseStorage.instance.ref().child('productImage').child('productImageUrl').delete();

The quotes around 'productImageUrl' are a mistake there. With this code it tries to delete the image named productImageUrl, which is not what your image is called.

That the very least it should be:

await FirebaseStorage.instance.ref().child('productImage').child(productImageUrl).delete();

By removing the quotes from around productImageUrl, the code will use the value of the variable.

But more likely the productImageUrl contains a download URL, in which case your first need to map that back to a Storage Reference by calling the refFromURL method:

var storageRef = FirebaseStorage.instance.refFromURL(productImageUrl);
await storageRef.delete();
