- Replaced instances of the Logger package with a custom appLogger for consistent logging. - Introduced app_logger.dart to manage logging with file output and storage permissions. - Updated all controllers (e.g., DashboardController, EmployeesScreenController, etc.) to use appLogger for logging messages. - Ensured that logging messages are appropriately categorized (info, warning, error) throughout the application. - Implemented a file logging mechanism to store logs in a designated directory. - Cleaned up old log files to maintain only the most recent logs.
