Answer 1

why do you have a , in your url?:

Future<void> fetchAndSetProducts() async {
final url = Uri.https('flutter-project-c43e5-default-rtdb.firebaseio.com',
    '/products.json?auth=$authToken');
...

change this block to:

Future<void> fetchAndSetProducts() async {
final url = Uri.https('flutter-project-c43e5-default-rtdb.firebaseio.com/products.json?auth=$authToken');
...
