From f5239d4a2a00199904e6f919451eaf44bbbdf1ff Mon Sep 17 00:00:00 2001 From: Mikkeli Matlock Date: Wed, 20 Aug 2025 23:30:14 +0900 Subject: [PATCH] Implement complete GPS speedometer functionality MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Features implemented: - Real-time GPS speed tracking with permission handling - Customizable speed units (km/h, mph) with persistent settings - Digital and analog speedometer display styles - Dark/light theme support with system integration - Optional metrics: coordinates, distance, trip time, GPS accuracy - Trip reset functionality and error handling - Modular architecture with Provider state management Technical details: - Added dependencies: geolocator, permission_handler, provider, shared_preferences - Configured Android location permissions (FINE_LOCATION, COARSE_LOCATION) - Portrait orientation lock for mobile-first experience - Extensible settings system for future customization options - Clean separation of concerns: providers, screens, widgets 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .claude/settings.local.json | 6 +- android/app/src/main/AndroidManifest.xml | 6 + lib/main.dart | 143 ++------- lib/providers/location_provider.dart | 136 ++++++++ lib/providers/settings_provider.dart | 98 ++++++ lib/screens/settings_screen.dart | 186 +++++++++++ lib/screens/speedometer_screen.dart | 170 ++++++++++ lib/widgets/analog_speedometer.dart | 215 +++++++++++++ lib/widgets/digital_speedometer.dart | 113 +++++++ lib/widgets/info_panel.dart | 150 +++++++++ macos/Flutter/GeneratedPluginRegistrant.swift | 4 + pubspec.lock | 295 +++++++++++++++++- pubspec.yaml | 14 +- test/widget_test.dart | 17 +- .../flutter/generated_plugin_registrant.cc | 6 + windows/flutter/generated_plugins.cmake | 2 + 16 files changed, 1435 insertions(+), 126 deletions(-) create mode 100644 lib/providers/location_provider.dart create mode 100644 lib/providers/settings_provider.dart create mode 100644 lib/screens/settings_screen.dart create mode 100644 lib/screens/speedometer_screen.dart create mode 100644 lib/widgets/analog_speedometer.dart create mode 100644 lib/widgets/digital_speedometer.dart create mode 100644 lib/widgets/info_panel.dart diff --git a/.claude/settings.local.json b/.claude/settings.local.json index f173426..d4272f2 100644 --- a/.claude/settings.local.json +++ b/.claude/settings.local.json @@ -4,7 +4,11 @@ "Bash(gh:*)", "Bash(git init:*)", "Bash(git add:*)", - "Bash(git config:*)" + "Bash(git config:*)", + "Bash(flutter pub:*)", + "Bash(mkdir:*)", + "Bash(flutter analyze:*)", + "Bash(flutter build:*)" ], "defaultMode": "acceptEdits" } diff --git a/android/app/src/main/AndroidManifest.xml b/android/app/src/main/AndroidManifest.xml index 77efd62..3643690 100644 --- a/android/app/src/main/AndroidManifest.xml +++ b/android/app/src/main/AndroidManifest.xml @@ -1,4 +1,10 @@ + + + + + + createState() => _MyHomePageState(); -} - -class _MyHomePageState extends State { - int _counter = 0; - - void _incrementCounter() { - setState(() { - // This call to setState tells the Flutter framework that something has - // changed in this State, which causes it to rerun the build method below - // so that the display can reflect the updated values.
