Bug: We're stuck in dark mode!

[CherryCIC]

Bug: Dark Mode Toggle Has No Effect

Environment

• Platforms: iOS & Android (TestFlight + debug builds)
• Devices: Multiple (e.g., iPhone, Pixel)
• App Version: 1.2.3 (build 456)
• Flutter SDK: 3.16.8

App State

• Always in dark mode, regardless of toggle

Steps to Reproduce

1. Open the app and navigate to Settings.
2. Toggle Dark Mode off.
3. Navigate through Login, Photo Picker, and other screens.

Expected Behaviour

• App respects user theme selection:
  • Light theme when dark mode is toggled off.
  • Dark theme when toggled on.
  • (If supported) “System” option mirrors OS light/dark mode.

Actual Behaviour

• App remains in dark mode regardless of toggle state.
• Affects readability of login page text and photo picker icons due to low contrast.

User Impact

• Users cannot switch to light mode, impacting accessibility and user preference.
• Reduced readability in some UI areas.

Acceptance Criteria

• Theme switches immediately on toggle (no restart required).
• Selected theme persists on cold start and resume.
• If “System” option is present, theme syncs with OS mode.
• All screens (Login, Photo Picker, etc.) respect chosen theme (no hardcoded overrides).

Technical Notes

• Ensure a single source of truth for theme (e.g., ThemeMode at MaterialApp).
• Persist theme selection in local storage (SharedPreferences / Hive).
• Audit for overrides like Brightness.dark.
• Add widget tests for:
  • Toggle behaviour
  • Persistence after restart
  • System theme sync

@littleangelx Hi Rachel! I hope you're doing well. I appreciate your genuine help and enthusiasm recently, thank you.
Would you like to take a look at this for me please?
The app is currently in perpetual dark-mode and the toggle seems not to register a change. Let me know if you'd like to take a look into it, as having a dark mode/ light mode toggle that works at this stage would just be so cool and frankly I believe dark mode is most definitely integral to cherry!🤣

@matgallacher Hi Mat! I hope you're doing alright mate.
I wondered if you would like to help Rachel on this one? I remember when we had a call to discuss the dark mode, where you showed it to me. You might have an understanding of the setup that could potentially really help Rachel out with this one, your assistance would be appreciated.
