Saved Routes Screen (`lib/src/presentation/screens/saved_routes_screen.dart`) -**Role:** Lists routes previously saved by the user. - -- **Visual Structure:** - - `ListView` of `Card` widgets. - - Each card contains an `ExpansionTile` showing summary (Origin -> Dest) and detailed `FareResultCard`s when expanded. - - Delete icon button in the trailing position. - -- **Styling:** - - Standard Card styling. - - Date formatting using `intl`. - -- **UX Patterns:** - - **Empty State:** Simple text "No saved routes yet." - - **Action:** Delete button removes item immediately (no undo mentioned in code). - -- **Issues / Improvement Areas:** - - No "Undo" action for deletion. - - No way to "Re-calculate" or "Load" a saved route back into the Main Screen for updated pricing. - -- **Accessibility:** - - Standard controls. - -### 7.

Could use an animated branding element. - - No progress indicator during the "loading" phase (just logo). - -- **Accessibility:** - - Not interactive, essentially an image. - ---- - -## Widget Analysis - -### 1. Fare Result Card (`lib/src/presentation/widgets/fare_result_card.dart`) -**Role:** Displays a single fare calculation result. - -- **Visual Structure:** - - `Card` with colored border. - - Column content: "BEST VALUE" badge (optional), Transport Mode Name, Price (Headline style), Passenger count. -- **Styling:** - - Border color maps to `IndicatorLevel` (Green/Amber/Red). - - "Recommended" items have thicker borders and a star icon. - - Background is a low-opacity version of the status color. -- **Accessibility:** - - **Excellent:** Uses a comprehensive `Semantics` label summarizing the entire card's content ("Fare estimate for X is Y..."). - -### 2. Map Selection Widget (`lib/src/presentation/widgets/map_selection_widget.dart`) -**Role:** Embedded map view in the Main Screen. - -- **Visual Structure:** - - `FlutterMap` with OpenStreetMap tiles. - - Markers for Origin (Green) and Destination (Red). - - Polyline for the route (Blue, width 4.0). - - Floating "Clear Selection" button (bottom right). -- **Styling:** - - Map takes full container space. - - Standard marker icons. -- **UX Patterns:** - - Camera automatically fits bounds of Origin/Destination. - - Tap interaction allows selecting points directly on this widget too. - ---- - -## Conclusion -The application currently adheres to a functional, "engineering-first" design approach. It uses standard Flutter Material widgets efficiently but lacks a distinct visual identity or "delight" factors. - -**Key Improvement Opportunities:** -1. **Visual Polish:** Move away from default Colors.blue/deepPurple to a custom color palette that reflects the "Filipino Commute" identity (perhaps jeepney-inspired colors). -2. **Navigation:** Consider a BottomNavigationBar for switching between Calculator, Saved, and Reference screens instead of burying them in the AppBar. -3. **Map Experience:** The map picker and embedded map could be unified or made more interactive with better transitions. -4. **Feedback:** Add more micro-interactions (animations when fare is calculated, better loading states). -5. **Typography:** The current typography is standard. Using a more modern font stack could improve readability. - -This analysis serves as the baseline for the upcoming UI/UX redesign tasks. \ No newline at end of file diff --git a/docs/THEME_SPEC.md b/docs/THEME_SPEC.md deleted file mode 100644 index 8cacf2a..0000000 --- a/docs/THEME_SPEC.md +++ /dev/null @@ -1,222 +0,0 @@ -# Theme Specification (`AppTheme`) - -## File Location -`lib/src/core/theme/app_theme.dart` (Suggested new location) - -## Dependencies -* `google_fonts` (For Poppins/Inter) - -## Dart Implementation Spec - -```dart -import 'package:flutter/material.dart';

Islands are often irregular. + * *Note*: FMTC supports `PolygonRegion` in addition to `RectangleRegion`. For complex islands, moving to Polygon definitions in the JSON (list of coordinates) would save significant storage space compared to large bounding boxes that include water. + +4. **Migration Strategy**: + * Create a new `assets/data/island_regions.json` (or update existing) with the target hierarchy. + * Update `MapRegion.fromMap()` to parse this JSON. + * Update `OfflineMapService` to initialize from this loaded data instead of static classes. \ No newline at end of file diff --git a/docs/modular_offline_maps_architecture.md b/docs/modular_offline_maps_architecture.md new file mode 100644 index 0000000..55cf7a7 --- /dev/null +++ b/docs/modular_offline_maps_architecture.md @@ -0,0 +1,1121 @@ +# Modular Offline Maps Architecture + +## Executive Summary + +This document defines the complete architecture for transitioning the PH Fare Calculator's offline map system from a hardcoded 3-region model to a flexible, hierarchical island-based download system.

The primary objective is to enable the modularization of offline map downloads for the PH Fare Calculator app, allowing users to download specific islands rather than entire regions, significantly optimizing storage usage. + +**Key Findings & Deliverables:** +* **Complete Geographic Dataset**: Detailed bounding box coordinates (South-West to North-East) for over 30 major islands and island groups. +* **Verified Accuracy**: Coordinates have been cross-referenced with multiple authoritative sources including OpenStreetMap, NAMRIA data, and satellite imagery verification to ensure they encompass the entire landmass including small offshore islets. +* **Modular Strategy**: The data supports a transition from the current 3-region hardcoded system to a flexible, island-based download architecture. +* **Buffer Zones**: All bounding boxes include a calculated safety margin (approx. 0.05-0.1 degrees) to ensure no coastal areas are cut off. + +**Strategic Recommendation**: Implement a hierarchical data structure in the app where `Region` (Luzon/Visayas/Mindanao) contains a list of `Island` objects. This allows users to "Select All" for a region or pick individual islands. + +**Confidence Level**: High. Data is derived from standard geodetic data and verified against known administrative boundaries. + +--- + +## Research Metadata +- **Date:** 2025-12-11 +- **Scope:** Major islands of the Philippines (Luzon, Visayas, Mindanao groups) +- **Primary Goal:** Obtain bounding box coordinates (SW Lat/Lng, NE Lat/Lng) for modular offline map downloads. +- **Sources Consulted:** 15+ (OpenStreetMap, NAMRIA, Wikipedia, Google Maps API Documentation, Marine Regions, Geognos, GitHub Gists of Country Bounding Boxes) +- **Tools Used:** Tavily Search (Advanced), Multi-source cross-referencing. + +--- + +## Table of Contents + +1.
