- Fix AppState: remove removed connectivity package, fix imports (latlong2), make nullable fields optional - Fix User model: use const empty strings in const constructor instead of null - Fix model builders: add required ObjectId parameters to YourLocation and FireNotification - Implement Comparable instead of extending it for BasicLocation - Fix nullable callback handling in appActions and middleware (Completer<Null>?) - Add null checks for BuildContext in dialogs (fireAlert, homePage, etc.) - Fix nullable scaffold state access using ?. operator (activeFires, fireNotificationList) - Handle nullable FireNotification and YourLocation in genericMapBottom - Fix list type casting for widgets that can be null (<Widget?> with filtering) - Add ObjectId imports where needed for model creation - Fix Key? nullable parameter in introPage - Add required parameters to markdownPage and slider constructors - Remove connectivity-related code and imports (package removed) - Handle nullable Completer in fetchDataMiddleware All 104 errors resolved. 0 errors, 61 warnings/info remaining.
