How it works...

The Firebase Storage API lets you upload files to the Google Cloud. These files can then be shared and used based on your app's needs.

The first step to leverage this service in Flutter is to add the firebase_storage dependency to your pubspec.yaml file and import it into your files. In this way, you get access to the FirebaseStorage instance, which is the entry point for any future action on the files. In this recipe, you retrieved the instance with the following command:

FirebaseStorage storage = FirebaseStorage.instance;

From storage, you can then get a Reference object. This is a pointer to a storage object that you can use to upload, download, and delete objects. In this recipe, we created a Reference object, passing the name of the file that would later be uploaded, with the following command:

Reference ref = storage.ref(fileName);

Once you create a Reference object, you can then upload a file to that reference with the putFile method, passing the...
