Firebase Storage upload picture from gallery Flutter (No error)

I want to upload a picture choosen from gallery to Firestore Storage, this is my first time but I read docs and took a look on the internet, this is what I wrote (it works without errors but doing nothing on the storage).

Code below, I tested imgFromGallery and it works maybe the problem are Storage functions.

Future<File> imgFromGallery() async {
  try {
    final ImagePicker _picker = ImagePicker();
    final PickedFile imageFile =
        await _picker.getImage(source: ImageSource.gallery, imageQuality: 50);

    //If there is no image selected, return.
    if (imageFile == null) return null;
    //File created.
    File tmpFile = File(imageFile.path);
    //it gives path to a directory - path_provider package.
    final appDir = await getApplicationDocumentsDirectory();
//filename - returns last part after the separator - path package.
    final fileName = tmpFile.path.split('/').last;
//copy the file to the specified directory and return File instance.
    return tmpFile = await tmpFile.copy('${appDir.path}/$fileName');
  } catch (e) {
    print(e);
    return null;
  }
}

//Save file to Storage function

Future<void> setPicture(String pathStorage) async {
    try {
      final File file = await imgFromGallery();
      if (file == null) return;
      FirebaseStorage.instance.ref(pathStorage).putFile(file);
      return;
    } catch (e) {
      print(e);
    }
  }

P.S. : I would like to return the URL of the uploaded picture as return of "setPicture" but I still don't know how to do this.

You are just few steps away!

TaskSnapshot task = await FirebaseStorage.instance.ref(pathStorage).putFile(file);

After successful upload, you will get TaskSnapshot. That has a reference member ref.

String image_url = await task.ref.getDownloadURL();

This image_url is the URL of the uploaded picture.
