Fix syntax error in main.dart file

[fatma-khaledd]

Closes #240

Fix Syntax Error in main.dart

Problem

The main() function closing bracket was missing, causing all classes (MyApp, WidgetsBindingObserverWidget, AppRouteObserver) to be defined inside main() instead of at the top level. This prevented the app from running.

Solution

Added the missing closing bracket } for main() after runApp(), and removed the extra } at the end of the file.

Changes

• Fixed missing } to close main() function after runApp()
• Moved all class definitions outside of main() to the correct top-level scope

Testing

App runs successfully after the fix.

Summary by CodeRabbit

• Refactor
  • Internal code structure reorganization and formatting improvements for better maintainability.

Poem

🐰 A tangled nest of classes found,
Indentation all turned 'round,
With careful paws I sort and mend,
No logic breaks—just format bends!
The compiler hops with joy at last! ✨
