        fun hasPermissions(context: Context) = PERMISSIONS_REQUIRED.all {

推荐答案

查看 Google Accompanist 的 Jetpack Compose 权限.

Check out Google Accompanist's Jetpack Compose Permissions.

请记住，在撰写本文时，该 API 仍被认为是实验性的，并且在使用时需要 @ExperimentalPermissionsApi 注释.

Bear in mind that, at the time of writing, the API is still considered experimental and will require the @ExperimentalPermissionsApi annotation when used.
