…`MutableMultiplePermissionsState.shouldShowRationale`
`launchMultiplePermissionRequest` is typically called when
`shouldShowRationale` returns true. However, what may not be as obvious
is that `launchMultiplePermissionRequest` appears to result in a noop if
one or more permissions in `MutableMultiplePermissionsState` are
`Denied(shouldShowRationale=false)`. This caused issues for us in some
code similar to this:
```kotlin
val permissions =
rememberMultiplePermissionsState(
listOf(
ACCESS_FINE_LOCATION,
ACCESS_BACKGROUND_LOCATION,
)
)
when {
// Granted
permissions.allPermissionsGranted -> /* ... */,
// Denied, but I can ask the user
permissions.shouldShowRationale ->
// UNEXPECTED: Does not trigger!
permissions.launchMultiplePermissionRequest()
// Denied and I may not ask the user.
else -> /* ... */
}
```
The fix would seem to be to additionally make sure that there are no
permissions with the `Denied(shouldShowRationale=false)` status before
returning a truthy value from `shouldShowRationale`.

Sorry for the slow response here, I am planning to get to this. Just trying to get the beta release out first |

Adding the fix I proposed in #1781
Fixes #1781
Additional complication:
I have indications that
ACCESS_BACKGROUND_LOCATIONmay beDenied(shouldShowRationale=false)whileACCESS_FINE_LOCATIONisDenied(shouldShowRationale=true). It then seems likeACCESS_BACKGROUND_LOCATIONshifts toDenied(shouldShowRationale=true)onceACCESS_FINE_LOCATIONis granted.I have not yet confirmed this but something seems to be acting strange with these two. If the above description is correct, the proposed solution in this PR is insufficient (though covering an unexpected gap that exists today).
I think someone should take a closer look and disprove the above theory before merging this (that'll probably be a few months out on my end - if even then).
