我正在使用Flutter和Firebase构建应用程序。我的部分代码可以正常工作
final collection = Firestore.instance.collection('regions').orderBy('region_id');
collection.getDocuments().then((data){
print(data);
})
.catchError((e){print(e);});
那之后我得到
W/.example.herme(13551): Unsupported class loader
I/.example.herme(13551): The ClassLoaderContext is a special shared library.
I/.example.herme(13551): The ClassLoaderContext is a special shared library.
W/.example.herme(13551): Skipping duplicate class check due to unsupported classloader
I/.example.herme(13551): The ClassLoaderContext is a special shared library.
W/.example.herme(13551): Accessing hidden method Ljava/security/spec/ECParameterSpec;->getCurveName()Ljava/lang/String; (light greylist, reflection)
依此类推,在Firebase Firestore中,我有一个名为region的集合,上面有16个文档,每个文档内部都有一个称为comune的集合,上面有文档。
该错误是什么意思?与收藏有关吗?
