Google Maps Settings

Create one at console.cloud.google.com with the "Maps SDK for Android" and "Maps SDK for iOS" APIs enabled. Both apps read this value via get_app_settings.php and cache it locally, so updating it here reaches every device without a code change - except the native map tiles on Android/iOS, which must also have the same key baked into each app's build (AndroidManifest.xml / AppDelegate.swift) before it takes effect there, since that's a platform requirement neither Flutter nor this admin panel can override at runtime. Keep both in sync when you rotate the key.
