Ok, following your guide (@ChennaReddy and @aziza), this is the way I fix my code:

body: new Column(
        children: [
          new Flexible(
            child: new FirebaseAnimatedList(
              query: FirebaseDatabase.instance
                  .reference()
                  .child('products')
                  .orderByChild('Active')           // line changed
                  .equalTo(true),                   // line added
              padding: new EdgeInsets.all(8.0),
              reverse: false,
              itemBuilder: (_, DataSnapshot snapshot,
                  Animation animation, int x) {
                return new ProductItem(
                    snapshot: snapshot, animation: animation);
              },
            ),
          ),
        ],
      ),

However, I need the resulting query order by 'order' which is a integer field (or attribute) that some admin users can change (update). So final users can see data ordered by 'order' (but only 'Active'=true as you help me to solve).
