[iOS] Requesting location always permissions does not return status when requesting more than once or selecting while using

[elouiestudent]

🐛 Bug Report

Upon either selecting while using after first requesting for always permissions or requesting for always permissions more than once, method hangs and does not return permission status.

Expected behavior

Method would return PermissionStatus.denied when user selects while using and return current PermissionStatus in additional calls to request always permissions.

Reproduction steps

• Request while using permissions
• Grant while using permissions
• Request always permissions
• Select while using in popup

Configuration

Version: 3.0.0+1

Platform:

• 📱 iOS
• 🤖 Android

When testing on iOS emulator, after reproducing and closing the example app. The application says PermissionStatus.granted on locationAlways.

[elouiestudent]

When testing on iOS emulator and real device, the application never returns a value when location permissions are kept to while using upon requestion for location always permissions.

When permissions are granted for location always the request returns granted as intended.
