## Overview

car64 helps collectors scan model IDs, organize personal and shared collections, and keep a clean catalog with community validation/reporting flows.

## Features

- Fast scan workflow (camera OCR + manual entry fallback)
- Multi-collection support with member roles (owner/member/viewer)
- Private image storage with signed URL access
- Collection collaboration and member management
- Community validation and issue reporting for catalog entries
- Profile/settings flows including password updates and report tracking

## Tech Stack

- Flutter (Material 3)
- Supabase (Auth, PostgREST, Storage, RPC)
- Shared Preferences (local settings)
- Google ML Kit Text Recognition (scanner)

## Prerequisites

- Flutter SDK (stable)
- A Supabase project
- For iOS builds: macOS + Xcode

## Configuration

Supabase config is required at runtime/build time (no embedded fallback values).

### Option A: local defines file (recommended)

Use:

- `.env/flutter_defines.json` (local, ignored by git)
- `.env/flutter_defines.example.json` (tracked template)

Expected shape:

```json
{
  "SUPABASE_URL": "https://your-project.supabase.co",
  "SUPABASE_ANON_KEY": "your_anon_key",
  "SUPABASE_USE_PKCE": "true"
}
```

### Option B: direct dart-define flags

```bash
flutter run \
  --dart-define=SUPABASE_URL=https://your-project.supabase.co \
  --dart-define=SUPABASE_ANON_KEY=your_anon_key \
  --dart-define=SUPABASE_USE_PKCE=true
```

## Getting Started

1. Install dependencies

```bash
flutter pub get
```

2. Run analyze

```bash
flutter analyze
```

3. Launch app

```bash
flutter run
```

## VS Code Workflows

### Run / Debug (`launch.json`)

Use **Run and Debug** with:

- `Flutter (Supabase Local - Debug)`
- `Flutter (Supabase Local - Profile)`
- `Flutter (Supabase Local - Release)`

These configurations read:

`--dart-define-from-file=.env/flutter_defines.json`

### Build Tasks (`tasks.json`)

Use **Terminal → Run Task**:

- `Flutter Build APK (Release)`
- `Flutter Build App Bundle (Release)`
- `Flutter Build iOS IPA (Release)`

## Project Structure (high level)

- `lib/screens/` UI screens and flows
- `lib/services/` Supabase integration/services
- `lib/widgets/` reusable UI components
- `lib/utils/` helpers and formatting utilities
- `lib/theme/` app theme and colors

## Security Notes

- Supabase anon keys are intentionally client-side, but RLS and RPC permissions must be strict.
- Sensitive local config files are git-ignored.
- User-facing errors are sanitized and shown via global overlays.
