Get Download URL from Firebase Storage in Flutter

Question

I'm currently exploring Flutter, I found there is an official Firebase Storage plugin in Flutter firebase_storage I have storage reference like this one:

final StorageReference ref = FirebaseStorage.instance.ref().child("default.png");

But there is no method to get download URL from that StorageReference.

Answer 1

If the above solution doesn't work, try this:

Future<String> uploadImage(var imageFile ) async {
    StorageReference ref = storage.ref().child("/photo.jpg");
    StorageUploadTask uploadTask = ref.putFile(imageFile);

    var dowurl = await (await uploadTask.onComplete).ref.getDownloadURL();
    url = dowurl.toString();

    return url; 
}

Answer 2

use url like this:

printUrl() async {
    StorageReference ref = 
        FirebaseStorage.instance.ref().child("images/sky.jpg");
    String url = (await ref.getDownloadURL()).toString();
    print(url);
}
