What problem does this feature solve?

全局 loading 的问题。

What does the proposed API look like?

• status: loading | finish | error, 加载状态
• mask: boolean， 是否显示遮罩

最好提供一个 provider， 然后提供 useLoadingBar 的 API 形式调用。

What does the proposed api look like?

-STatus: Loading | Finish | Error, loading status
-Mask: Boolean, whether to show a mask

It is best to provide a provider, and then provide an API form of userLoadingbar.
