firebase::storage::Storage

#include <storage.h>

Entry point for the Firebase C++ SDK for Cloud Storage.

Summary

To use the SDK, call firebase::storage::Storage::GetInstance() to obtain an instance of Storage, then use GetReference() to obtain references to child blobs. From there you can upload data with StorageReference::PutStream(), get data via StorageReference::GetStream().
