我的 FirebaseStorage 方法没有在 Flutter 中运行。在 `firebase_storage: ^4.0.0` 之后

Question

我的问题

任何人都可以帮助我正在尝试将我的图像发送到 firebase 存储，然后检索下载 URL 并保存到 firebasefirestore。但是我的 FirebaseStorage 方法没有运行。

发生在firebase_storage: ^4.0.0 更新

之后

我的FirebaseStorage().ref().child('path).putFile() 方法没有运行

FirebaseStorage()
             .ref()
             .child("Accounts Posts/Images/").putFile(//MyFIle);

这是我的代码

static final FirebaseStorage storage = FirebaseStorage.instance;
static final FirebaseFirestore _firestore = FirebaseFirestore.instance;

---

Future<dynamic> sendData(SearchTileModel st, List<File> data) async {
 bool completed = false;
 CollectionReference _collec = _firestore.collection('Accounts Posts');
 List<String> _imageUrls = [];
 print(data.length);
 data.length > 0
     ? data.asMap().forEach((
         index,
         element,
       ) async {
         print(index);
         print(element);
         String downloadUrl;
///////  HERE this code doesn't get called up  ////////////
         StorageTaskSnapshot snapshot = await FirebaseStorage()
             .ref()
             .child("Accounts Posts/Images/${index}")
             .putFile(element)
             .onComplete
             .then((value) {
           downloadUrl = value.ref.getDownloadURL().toString();
           return;
         });
         print(downloadUrl);
         print(snapshot);
         print(snapshot.error);
         if (snapshot.error == null) {
           await snapshot.ref
               .getDownloadURL()
               .then((value) => downloadUrl = value.toString());
           print(downloadUrl);
           _imageUrls.insert(index, downloadUrl);
           if (st.images.length == _imageUrls.length) {
             SearchTileModel newModel = st;
             newModel.images = _imageUrls;
             await _collec
                 .doc('${newModel.placeName} : name')
                .set(
                  st.toJson(),
                  SetOptions(mergeFields: [
                    'images',
                  ]),
                )
                .whenComplete(() {
              return completed = true;
            }).catchError((onError) {
              print('${onError.toString()}');
              completed = false;
            });
          }
        } else {
          completed = false;
          print('Error from image repo ${snapshot.error.toString()}');
          throw ('This file is not an image');
        }
      })
    : print('No Images Selected');
if (data.length == 0) {
  SearchTileModel newModel = st;
  newModel.images = _imageUrls;
  await _collec
      .doc('${newModel.placeName} : name')
      .set(
        st.toJson(),
        SetOptions(mergeFields: [
          'images',
        ]),
      )
      .whenComplete(() {
    return completed = true;
  }).catchError((onError) {
    print('${onError.toString()}');
    completed = false;
  });
}
return completed;
}

这里是调试控制台输出

所有显示该方法的打印语句都没有运行。 我还认为由于await 这需要时间，但等了 10 分钟后没有任何反应。

更新得到这些行

我也改变了firebase存储的规则

rules_version = '2';
service firebase.storage {
 match /b/{bucket}/o {
   match /{allPaths=**} {
     allow read, write ;
   }
 }
}

我可以看到您正在使用 .ref() 来获取参考。 查看documentation，可以看到使用的是getReference()

StorageReference storageRef = storage.getReference();

因此，最好按照文档中的说明设置存储引用。上传文件的代码也是这样的：

Uri file = Uri.fromFile(new File("path/to/images/rivers.jpg"));
StorageReference riversRef = storageRef.child("images/"+file.getLastPathSegment());
uploadTask = riversRef.putFile(file);
