This commit enriches the `SettingsViewModel` by integrating state persistence functionality and a sign-out method, thus ensuring a more robust and user-friendly settings feature.
Key Enhancements:
1. **State Persistence**:
- Leveraging the `shared_preferences` package, the app now stores and retrieves user preferences related to app settings, ensuring consistency across app restarts.
- Preferences like Dark Mode, Developer Mode, Base URL, and Continuous Mode Steps are persistently stored and loaded when the ViewModel is initialized.
2. **Sign Out Method**:
- A `signOut` method has been introduced in the ViewModel, utilizing the `AuthService` to facilitate user sign-out processes.
- This addition allows for seamless integration of sign-out functionality within the settings interface, granting users the ability to easily terminate sessions.
3. **SettingsView Enhancement**:
- The `SettingsView` has been adapted to incorporate a UI element invoking the `signOut` method, enhancing user interaction within the settings environment.
This enhancement not only bolsters the resilience and usability of the app’s settings but also lays down a structured approach for potential future additions to user preferences and settings-related functionalities.
This commit introduces the `SettingsViewModel` class, part of the MVVM architecture, responsible for managing the state and business logic for the settings feature of the app. This ViewModel is associated with the `SettingsView`.
Features Managed by this ViewModel:
- Dark Mode: Toggle the state of Dark Mode and notify listeners.
- Developer Mode: Toggle the state of Developer Mode and notify listeners.
- Base URL: Update the state of Base URL and notify listeners.
- Continuous Mode Steps: Increment and decrement the number of Continuous Mode Steps and notify listeners.
Each change in the state is followed by a notification to the listeners to rebuild the UI components that depend on this state, ensuring a reactive UI. To-do comments have been added where the state needs to be persisted or synchronized with a server.
