上传图片的代码：

    uploadImage() {
var randomno = Random(25);
final StorageReference firebaseStorageRef = FirebaseStorage.instance
    .ref()
    .child('profilepics/${randomno.nextInt(5000).toString()}.jpg');
StorageUploadTask task = firebaseStorageRef.putFile(newDp);

task.onComplete.then((value) {
  userManagement
      .updateProfilePic(value.uploadSessionUri.toString())
      .then((val) {
    Navigator.pushReplacement(
        context, MaterialPageRoute(builder: (context) => HmPg()));
  }).catchError((e) {
    print(e);
  });
}).catchError((e) {
  print(e);
});
    }

在我的 firebase 存储中，我可以看到我上传的图像，即使图像的 url 也可以正常工作。我将安全规则更新为公开，但仍然抛出相同的异常。允许storage我的应用程序的权限，更新AndroidManifest仍然没有成功。

您在此处尝试获取的是文件上传的上传 URL。我建议从上传任务中获取下载 URL 以访问图像。

UploadTask task = firebaseStorageRef.putFile(newDp);

task.then((TaskSnapshot taskSnapshot) {
  debugPrint('Download URL: ${taskSnapshot.ref.getDownloadURL()}');
});

然后，您可以使用此下载 URL 从 Firebase 存储访问文件。
