# timetracker

A cross-platform time tracker built with Flutter for the frontend and Rust for the backend logic. Communication is handled via `flutter_rust_bridge`, and data is stored locally on the device using SQLite. The user interface adapts to the native look-and-feel of Android and iOS thanks to `flutter_platform_widgets`.

## Features

* **Time Tracking:** Start and stop time tracking entries.
* **Tag Management:**
    * Create new tags.
    * List all tags.
    * Edit tag names (via swipe gesture).
    * Delete tags (via swipe gesture, includes confirmation). Associated time entries will have their tag set to NULL.
* **Local Storage:** All data is securely stored in a local SQLite database on the device (managed by Rust).
* **Reporting:**
    * Display time entries filtered by period (Day, Week, Month, Year) and optionally by tag.
    * Total duration display for the filtered period.
    * Visualization using charts (`fl_chart`):
        * **Bar chart:** Distribution of daily time spent per tag for the selected period.
    * List view for report entries.
    * **Pull-to-Refresh:** Manually refresh report data.
    * **Swipe-to-Delete:** Delete individual time entries directly from the report list via swipe gesture (with confirmation).
* **Platform-Adaptive UI:** Uses `flutter_platform_widgets` to provide a native appearance on Android (Material Design) and iOS (Cupertino).

## Technologies

* **Frontend:** Flutter / Dart
    * State Management: `provider`
    * UI Adaptation: `flutter_platform_widgets`
    * Charts: `fl_chart`
    * Swipe Actions: `flutter_slidable`
    * Intl: `intl`
* **Backend:** Rust
    * Database: SQLite (via `rusqlite`)
    * Error Handling: `anyhow`
    * Logging: `log`
* **Bridge:** `flutter_rust_bridge`
* **Build:** Cargo, Flutter Build Tools, Gradle (Android), Xcode (iOS)

## Architecture

The app follows a clear separation between UI and logic:

`Flutter UI (Widgets)` <-> `Dart Service Layer (TimeTrackingService)` <-> `flutter_rust_bridge (Generated Bindings)` <-> `Rust API (api.rs)` <-> `Rust DB Logic (database.rs)` <-> `SQLite Database`
