    uploadImageToFirebase() async {
    File yuklenecekDosya = _imagefile!;
    firebase_storage.Reference referansYol = firebase_storage
        .FirebaseStorage.instance
        .ref()
        .child("Profilresimleri")
        .child(user!.uid)
        .child("profilresmi.png");




    firebase_storage.UploadTask yuklemeGorevi =
        referansYol.putFile(yuklenecekDosya);
    yuklemeGorevi.then((s) {
      if (s.state.toString() == firebase_storage.TaskState.success.toString()) {
        downloadURL = referansYol.getDownloadURL().toString();
        print(referansYol.getDownloadURL().toString());
        print(referansYol.getDownloadURL().toString());
        print(referansYol.getDownloadURL().toString());
        print(referansYol.getDownloadURL().toString());
        print(referansYol.getDownloadURL().toString());

In the code, Firestore's set() method is getting called before the uploading is done. The execution of upload should return String but its asynchronous behaviour is expecting await before the execution happens (that's the reason you're getting the Future logged in console). You should await for storage to upload the file.

So the final code will be:

uploadImageToFirebase() async {
    File yuklenecekDosya = _imagefile!;
    firebase_storage.Reference referansYol = firebase_storage
        .FirebaseStorage.instance
        .ref()
        .child("Profilresimleri")
        .child(user!.uid)
        .child("profilresmi.png");


    firebase_storage.UploadTask yuklemeGorevi =
        referansYol.putFile(yuklenecekDosya);
    await yuklemeGorevi.then((s) {
      if (s.state.toString() == firebase_storage.TaskState.success.toString()) {
        downloadURL = referansYol.getDownloadURL().toString();
        print("Download URL: $downloadURL");
      }
    });

    await firestore
        .collection("Users")
        .doc(user!.uid)
        .set({"profilfotolink": downloadURL}, SetOptions(merge: true));
  }
