Pull Request Overview

This PR migrates the Flutter application to null safety and updates dependencies to their latest versions, including Flutter SDK 2.12+ requirement, updated packages (google_fonts, flutter_svg, flutter_local_notifications, etc.), and Android build tools. The changes include extensive code modifications to support null safety with proper nullable type annotations, deprecated API replacements (e.g., accentColor → hintColor, bodyText1 → bodyLarge), and refactored constructors with required parameters.

• Updated Flutter SDK requirement from >=2.7.0 <3.0.0 to >=2.12.0 <=3.0.6 to support null safety
• Migrated all code to null safety with proper nullable annotations (?, late, !)
• Replaced deprecated Flutter theme properties and text styles with current equivalents
• Updated Android build configuration for compatibility with newer tools

This creates a new empty RenderRepaintBoundary instead of retrieving it from the widget tree. The correct implementation should be _globalKey.currentContext!.findRenderObject() as RenderRepaintBoundary. The current code will fail because boundary.size will be null/invalid, and toImage() will not work on an unattached render object.

Parsing an empty string with DateTime.parse('') will throw a FormatException. Should use DateTime.tryParse() with a fallback, e.g., startDate: DateTime.tryParse(pref.getString("startTime") ?? '') ?? DateTime.now().

Suggested change

	startDate: DateTime.parse(pref.getString("startTime") ?? ''));
	startDate: DateTime.tryParse(pref.getString("startTime") ?? '') ?? DateTime.now());

[nitpick] Using cascade notation to call createParticles immediately after construction couples initialization logic with object creation. Consider moving createParticles(3) to a separate line or creating a factory method for better readability and separation of concerns.

Suggested change

	particles = ParticleSpawner(size: widget.widgetSize)..createParticles(3);
	particles = ParticleSpawner(size: widget.widgetSize);
	particles.createParticles(3);

Using an upper bound constraint <=3.0.6 may prevent the package from working with newer Flutter SDK versions. Consider using <4.0.0 or <3.1.0 instead to allow for patch and minor version updates within the major version range.

Suggested change

	sdk: ">=2.12.0 <=3.0.6"
	sdk: ">=2.12.0 <4.0.0"

The periodicallyShow method parameters are missing type annotations. Consider adding them: periodicallyShow({required String title, required String body}) for better type safety and API clarity.

Parameters title and body are missing type annotations and should be marked as required. Should be: static sendNotification({required String title, required String body}) async.

Parameters title and body are missing type annotations and should be marked as required. Should be: static dailyNotification({required String title, required String body}) async.

Suggested change

	static dailyNotification({title, body}) async {
	static dailyNotification({required String title, required String body}) async {

Parameters title and body are missing type annotations and should be marked as required. Should be: static scheduleNotification({required String title, required String body}) async.

Using locations.keys.first will set an arbitrary timezone instead of the device's actual local timezone. This breaks the app's notification scheduling functionality. Since flutter_native_timezone was removed, consider using an alternative like the timezone package's platform-specific methods or reinstating flutter_native_timezone.
