Crash on iOS when location permissions are system-wide disabled

UIAlertView crash on UIScene-based apps (iOS 26+)

Description

The location plugin crashes with a fatal NSObjectNotAvailableException on iOS 26 when used in a UIScene-based Flutter app (Flutter 3.38+). The crash occurs because LocationPlugin.m:198 uses the deprecated UIAlertView, which is now completely unavailable for UIScene-based applications.

Steps to Reproduce

1. Use Flutter 3.38+ (which migrates to FlutterSceneDelegate / UIScene lifecycle)
2. Run the app on a device with iOS 26
3. Disable Location Services system-wide (Settings > Privacy & Security > Location Services > OFF)
4. Trigger a location request that calls Location().requestService()

Expected Behavior

The plugin should display a prompt (using UIAlertController) asking the user to enable location services.

Actual Behavior

The app crashes with a fatal exception:

NSObjectNotAvailableException: UIAlertView is deprecated and unavailable for UIScene based applications, please use UIAlertController!

Environment

• Flutter: 3.38
• location package: 8.0.1
• iOS: 26.3.1
• Device: iPhone 14 Pro (iPhone14,5)

Root Cause

LocationPlugin.m at line 198 creates a UIAlertView to prompt the user to enable location services. UIAlertView has been deprecated since iOS 9 and is now fully unavailable in UIScene-based apps on iOS 26. The fix is to replace UIAlertView with UIAlertController.
