Summary of Changes

Hello @Gowreesh-A-M, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request integrates dark mode functionality into the application's core module. It transitions the main application theme to use Material Components' DayNight capabilities, ensuring that the UI automatically adapts to the system's dark or light theme setting. This change also involves creating specific values-night resource files for colors and styles, and updating existing layout files to reference these new, theme-aware color resources instead of fixed hexadecimal color codes.

Highlights

• DayNight Theme Integration: The application's main theme has been updated to Theme.MaterialComponents.DayNight.DarkActionBar.Bridge, enabling automatic adaptation to system-wide dark or light mode settings.
• Dark Mode Resources Added: New values-night resource files (colors.xml and styles.xml) have been introduced to define specific color and style overrides for dark mode, ensuring a consistent visual experience.
• Hardcoded Color Replacement: Numerous hardcoded hexadecimal color values in existing layout and drawable files have been replaced with references to theme-aware color resources, improving maintainability and dark mode compatibility.

Code Review

This pull request introduces dark mode support by updating themes to use DayNight and replacing hardcoded colors with color resources, which is a great improvement. The changes in the layout files and the vector drawable are well-executed and follow best practices for theming. My review includes a few suggestions for the newly added values-night/styles.xml file to replace newly introduced hardcoded colors with color resources. This will improve consistency and maintainability, aligning with the overall goal of this pull request.
