From 7d111ca202927f89bb3f7cfd09074c4045fdc973 Mon Sep 17 00:00:00 2001 From: Mikkeli Matlock Date: Tue, 10 Feb 2026 22:18:34 +0900 Subject: [PATCH] feat(02-02): migrate SpeedometerScreen from setState to Provider - Remove all shared state variables (unit, theme, GPS data, overlay status) - Keep only local widget state (_errorMessage, _isInBackground, timer) - Replace GPS initialization with context.read().initialize() - Replace overlay show/close/toggle with OverlayProvider methods - Replace theme/unit cycling with SettingsProvider.cycleTheme/Unit() - Remove isOverlayMode parameter (not used, overlay runs in separate isolate) - Wrap build with Selector for scaffold background - Use Selector for speed display (rebuilds only on speed change) - Use Selector for unit label (rebuilds only on unit change) - Use Selector for compass (rebuilds only on heading change) - Use context.read<> for event handlers (non-rebuilding access) - Simplify dispose() - only cancel background heartbeat timer and disable wakelock - Background heartbeat uses OverlayProvider.pushCurrentData() instead of inline logic - setState remains ONLY for _errorMessage (purely local error UI state) - Remove unused imports (speed_unit.dart, processed_gps_data.dart) - Portrait and landscape layouts both use Provider pattern --- lib/screens/speedometer_screen.dart | 706 ++++++++-------------------- 1 file changed, 200 insertions(+), 506 deletions(-) diff --git a/lib/screens/speedometer_screen.dart b/lib/screens/speedometer_screen.dart index 0ab73d7..cb0c036 100644 --- a/lib/screens/speedometer_screen.dart +++ b/lib/screens/speedometer_screen.dart @@ -1,256 +1,107 @@ import 'package:flutter/material.dart';
