# IngTrak

Personal finance app for **Enable Banking** (ING and other supported banks): transactions, labels, charts, budgets, look-ahead projections, and **PocketBase** cloud sync.

- **Package:** `com.ingtrak.app`
- **Platform:** Android (Flutter)
- **Flutter:** 3.47+ · **Dart:** 3.13+

## Features

- **Bank connect** — Enable Banking via backend API + in-app WebView; optional deep link `ingtrak://connected`
- **Home** — Balance, customizable layout: built-in sections (Transactions / Categorized / Recent) and filter widgets (stats or budget, half/full width, bar/pie/ring)
- **Transactions** — Search, filters, month heatmap, labels, notes, merchant / “apply to similar” rules
- **Overview** — Income/expense and label charts; save **favourite** chart filters
- **Look ahead** — Projected balance from recurring templates
- **Sync** — Bidirectional PocketBase sync (transactions, labels, annotations, favourites, home widgets, app prefs)
- **Theme** — Light / dark / system (local)
- **CSV** — Import ING CSV exports (Settings)

## Prerequisites

- [Flutter SDK](https://docs.flutter.dev/get-started/install) **3.47** or newer (Dart **3.13**)
- Android Studio / SDK (Java **17**), emulator or device
- Reachable **bank API** (`API_BASE_URL`) and **PocketBase** (`POCKETBASE_URL`)
- PocketBase auth collection **`usersapp`** (create this before running migrations)

```bash
flutter doctor
flutter doctor --android-licenses   # if prompted
```

## Quick start

```bash
cd ingtrakapp
cp .env.example .env          # edit URLs if needed
flutter pub get
flutter devices
flutter run                   # or: flutter run -d android
```

First Android build downloads Gradle and may take a few minutes.

### Useful commands

```bash
flutter analyze
flutter test
flutter run --release
flutter build apk
```

### Override config without editing `.env`

```bash
flutter run \
  --dart-define=API_BASE_URL=https://your-api.example \
  --dart-define=POCKETBASE_URL=https://your-pb.example \
  --dart-define=POCKETBASE_USERS_COLLECTION=usersapp
```

`--dart-define` values win over `.env`.

## Configuration

Copy [`.env.example`](.env.example) to `.env` (both are listed as Flutter assets). No secrets belong in these files.

| Variable | Purpose | Example |
|----------|---------|---------|
| `API_BASE_URL` | FastAPI bank / Enable Banking proxy | `https://ingtrak.satoshinakamoto.win` |
| `POCKETBASE_URL` | PocketBase instance | `https://pb.satoshinakamoto.win` |
| `POCKETBASE_USERS_COLLECTION` | Auth collection name | `usersapp` |

Loaded in `lib/utils/app_config.dart` at startup (`flutter_dotenv`). Fallbacks: hosted API URL, PocketBase `http://127.0.0.1:8090`.

### Bank redirect URIs

1. **HTTP callback (Enable Banking Control Panel / backend `REDIRECT_URI`):**  
   `{API_BASE_URL}/api/connect/callback`
2. **Optional app deep link** (after HTML bounce; not registered with Enable Banking):  
   `ingtrak://connected?code=…`  
   Declared in `AndroidManifest.xml` and handled via `app_links`.

## PocketBase setup

Migrations live in [`pocketbase/pb_migrations/`](pocketbase/pb_migrations/). They assume collection **`usersapp`** already exists.

### Collections

| Migration | Collection |
|-----------|------------|
| `1740000000` | `labels`, `tx_meta`, `merchant_rules`, `exact_templates` |
| `1740000001` | `transactions` |
| `1740000002` | `recurring_templates` |
| `1740000003` | `overview_favourites` |
| `1740000004`–`0006` | `home_filter_widgets` (+ half width, budget fields) |
| `1740000007` | `app_prefs` (Home section toggles + Look ahead years) |
| `1740000008` | `home_filter_widgets.label_match` (AND/OR) |

Built-in labels stay in the app; only **custom** labels sync. Rows are scoped per user (`user = @request.auth.id`).

### Apply migrations (typical Linux host)

```bash
sudo cp pocketbase/pb_migrations/*.js /opt/pocketbase/pb_migrations/
sudo chown pocketbase:pocketbase /opt/pocketbase/pb_migrations/*.js
sudo -u pocketbase /opt/pocketbase/pocketbase migrate up
sudo systemctl restart pocketbase
```

Adjust paths if your PocketBase install differs. After migrate, sign in on the app and run **Sync** (Account) so local data uploads.

### What syncs

- Bank transactions, labels, tx annotations, merchant/exact templates  
- Recurring templates, overview favourites, home filter widgets  
- App prefs: Home built-in section visibility, Look ahead max years  

Theme mode stays **device-local**.

## Launcher icon

Source: `assets/branding/app_icon.png`. Regenerate Android mipmaps:

```bash
dart run flutter_launcher_icons
```

(Configured in `pubspec.yaml`; iOS not enabled — no `ios/` folder yet.)

## First-run checklist

1. `.env` points at your API + PocketBase  
2. PocketBase migrations applied; `usersapp` exists; create an account (or use Admin → Users)  
3. Backend Enable Banking `REDIRECT_URI` matches `{API_BASE_URL}/api/connect/callback`  
4. `flutter run` → sign in → **Settings** → connect bank (or import CSV) → **Account** → Sync  

## License / privacy

Private project. Bank credentials and tokens are handled by your backend and Enable Banking — keep API and PocketBase access controlled.
