Challenges

1. Handling Multiple Service Types
   Challenge: Supporting multiple service types in one application is challenging due to variations in data models, business workflows, and user interfaces with role-based permissions.
   Solution: GetX manages multiple service types for the user by updating the UI dynamically through reactive state, showing only the relevant data, actions, and permissions.
2. UI Complexity in Multi-Service Workflow Design
   Challenge: Designing an intuitive UI is challenging because complex service workflows can confuse users and increase errors if not presented clearly.
   Solution: An intuitive UI for complex service workflows is achieved by using step-based screens, clear user guidance, and dynamic UI updates based on the selected service type.
3. Performance Optimization
   Challenge: Performance Optimization for Large Service Lists and Images
   Solution: Rendering large service lists and image-heavy content can degrade performance, causing slow loading and poor user experience.
