📙 Fragments

1. NotesListFragment

• Displays a list of saved notes.
• Tapping a note opens it in NoteDetailFragment for editing.

2. NoteDetailFragment

• Used for viewing, creating, editing, deleting, and sharing notes.
• Dynamically receives a note index via newInstance(index: Int) or opens in “new note” mode.

3. SettingsFragment

• Contains a toggle switch to change between Light and Dark themes.
• Uses SharedPreferences to persist user preference.

---

📂 NoteData.kt

Handles loading notes from a bundled notes.json file in the assets folder.

fun loadNotes(context: Context)

• Notes are loaded only once at startup.
• Currently, no persistent save (notes are lost after app restart).

---

🔘 BottomNavigationView

Located in activity_main.xml, this allows switching between fragments.

Menu Items:

• Notes: Shows all notes
• New: Opens a blank NoteDetailFragment
• Settings: Opens settings

Customizations:

• Icon and text tint are styled via ColorStateList files.
• Night mode support added using values-night/colors.xml.

---

🎨 Theme Support

• Uses AppCompatDelegate to switch themes.
• Custom themes defined in styles.xml (Light) and styles-night.xml (Dark).

---

📌 Known Limitations

• Notes are not saved persistently (no file/db saving after editing).
• No filtering or search on the notes list.
• Theme toggle does not dynamically update all UI elements (only after restart).

---

✅ To Do / Suggestions

• Implement persistent save using:
  • SharedPreferences
  • Room Database
  • Writing back to a JSON file
• Add filtering/search in NotesListFragment
• Improve UI with custom icons and animations
