期望效果

之前版本的api 有hasPermission 这个api 检查用户是否开启了推送通知的权限。

实际效果

新版本的库没有了hasPermission这个api。希望能重新加回来

No source files or tests are named. Start by locating the React Native plugin entry point and the Android and iOS permission APIs, then compare the current public API with the previous hasPermission behavior. Done means the API is available again and reports whether push-notification permission is enabled on both platforms.
