Can anyone tell me where I’m wrong with this code?

import 'package:anime_app/models/home_page.dart';
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';

class AnimeList extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: StreamBuilder(
          stream: Firestore.instance.collection('animes').snapshots(),
          builder: (BuildContext context, AsyncSnapshot snapshot) {
            if (!snapshot.hasData) return const Text('Carregando...');

            return ListView.builder(
              itemCount: snapshot.data.documents.length,
              itemBuilder: (BuildContext context, int index) {
                DocumentSnapshot doc = snapshot.data.documents[index];

                return ListView(
                  children: [
                    Container(
                      width: 100,
                      height: 100,
                      color: Colors.black,
                      decoration: BoxDecoration(
                        image: DecorationImage(
                            image: NetworkImage(doc['link_img'])),
                      ),
                    ),
                  ],
                );
              },
            );
          }),
    );
  }
}

  • (Read in relaxed tone) I think you are wrong in the question... What is happening or not? What is the expected result? Do any errors? xD

Welcome!

My dear, first of all, ensure that your code returns all the elements of the collection you want. After that you inject the elements into your list. There is a lot of data reading "permission" problem, which you can easily detect with a simple code:

void _onPressed() {
  firestoreInstance.collection("orders").get().then((querySnapshot) {
    querySnapshot.docs.forEach((result) {
      print(result.data());
    });
  });
}

Then I recommend you take a look at this component:

Cloud Firestore Plugin for Flutter
