From 96c9e59cf091a1fcfa8eec767d7667c8983e80d9 Mon Sep 17 00:00:00 2001 From: Jean-Philippe Brule Date: Sun, 16 Nov 2025 00:52:14 -0500 Subject: [PATCH] Implement system theme support and dark mode infrastructure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive theme management system with iOS system integration: - System theme detection: App follows iOS dark/light mode preferences via ThemeMode.system - Theme provider: Centralized theme state management with Riverpod (defaults to dark mode) - Settings toggle: Segmented button UI for Light/Dark/Auto theme selection - iOS system UI: Status bar and navigation bar adapt to current theme brightness Dark mode map styling (Android-ready): - DarkModeMapComponent: Reactive theme change detection with didChangeDependencies - Map style application: Custom dark JSON style for navigation maps - Theme-aware styling: Automatically applies/resets map style on theme changes - Note: Map styling currently Android-only due to iOS SDK limitations Updates: - main.dart: System UI overlay styling for iOS, theme provider integration - settings_page.dart: SegmentedButton theme toggle with icons - providers.dart: themeModeProvider for app-wide theme state - dark_mode_map.dart: Theme reactivity and style application logic - navigation_page.dart: Theme detection infrastructure (prepared for future use) Design philosophy: - Follow system preferences by default for native iOS experience - Manual override available for user preference - Clean separation between Flutter UI theming and native map styling 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- lib/components/dark_mode_map.dart | 44 ++++++- lib/main.dart | 16 ++- lib/pages/navigation_page.dart | 211 +++++++++++++++++++++++++----- lib/pages/settings_page.dart | 35 +++++ lib/providers/providers.dart | 7 + 5 files changed, 273 insertions(+), 40 deletions(-) diff --git a/lib/components/dark_mode_map.dart b/lib/components/dark_mode_map.dart index 8027ef2..4823f29 100644 --- a/lib/components/dark_mode_map.dart +++ b/lib/components/dark_mode_map.dart @@ -31,6 +31,7 @@ class _DarkModeMapComponentState extends State { bool _isInitializing = false; bool _isStartingNavigation = false; String _loadingMessage = 'Initializing...'; + Brightness?
