🚀 Getting Started

Prerequisites

Flutter SDK (>=3.0.0)
Dart SDK (>=3.0.0)
Android Studio / VS Code with Flutter extensions
Xcode (for iOS development on macOS)

Local Development with Supabase

For fully offline development using a local Supabase instance:

Install Supabase CLI
```
npm install -g supabase
```
Start local Supabase
```
supabase start
```
The CLI will print the API URL and anon key once running.

Configure .env for local

ENVIRONMENT=development
SUPABASE_URL=http://localhost:54321
SUPABASE_ANON_KEY=<anon key from supabase start output>

The default anon key is already available in .env.example under SUPABASE_LOCAL_ANON_KEY.

Apply migrations (if any)
```
supabase db reset
```
Run the app
```
flutter run
```
Stop local Supabase when done
```
supabase stop
```

Note: When using Android Emulator, replace localhost with 10.0.2.2:
SUPABASE_URL=http://10.0.2.2:54321

Installation

Create repository from template (if using GitHub template)
- Click "Use this template" button on GitHub
- Create a new repository from this template
- Clone your new repository:
```
git clone <your-repository-url>
cd <your-project-name>
```
OR clone directly (if not using template):
```
git clone <repository-url>
cd grex
```
Install dependencies
```
flutter pub get
```

Generate code (Freezed, JSON serialization)

flutter pub run build_runner build --delete-conflicting-outputs

Set up environment configuration — required, the build fails without it
```
# Copy the example environment file
cp .env.example .env

# Edit .env with your configuration — at minimum SUPABASE_URL and
# SUPABASE_ANON_KEY. See Configuration System section below.
```
.env is gitignored but declared as a Flutter asset in pubspec.yaml, so a fresh clone without it fails at bundle time with No file or variants found for asset: .env — before any Dart code runs. Creating the file (even empty) is mandatory; --dart-define alone is not enough. See SETUP.md.

⚠️ Do not put SUPABASE_SERVICE_ROLE_KEY in .env. Because .env ships as an app asset, that key would be extractable from any release build and bypasses all RLS. See F4 in the code audit.
Set up Git hooks (optional but recommended)

Linux/macOS:
```
./scripts/linux/development/setup-git-hooks.sh
```
Windows:
```
.\scripts\windows\development\setup-git-hooks.ps1
```
This will install Git hooks for:
- Code formatting checks (pre-commit)
- Commit message validation (commit-msg)
- Test execution (pre-push)
Run the app
```
flutter run
```

Social Login Setup

The app includes comprehensive social login integration with Google OAuth and Apple Sign In.

OAuth Provider Configuration

Google OAuth Setup:
- Create OAuth 2.0 Client ID in Google Cloud Console
- Add authorized redirect URIs: https://[project-id].supabase.co/auth/v1/callback
- Configure in Supabase Dashboard → Authentication → Providers
Apple Sign In Setup:
- Create Services ID in Apple Developer Portal
- Configure Sign In with Apple
- Generate private key (.p8 file)
- Configure in Supabase Dashboard → Authentication → Providers

Deep Link Configuration

Android (android/app/src/main/AndroidManifest.xml):

<intent-filter android:autoVerify="true">
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="io.supabase.grex"
          android:host="login-callback" />
</intent-filter>

iOS (ios/Runner/Info.plist):

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLName</key>
        <string>io.supabase.grex</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>io.supabase.grex</string>
        </array>
    </dict>
</array>

⚙️ Configuration System

This project includes a production-ready, multi-environment configuration system that supports:

Local Development: .env files for easy local configuration
CI/CD: --dart-define flags for build-time configuration
Fallback Chain: .env → --dart-define → defaults
Environment-Aware Defaults: Different configurations per environment
Feature Flags: Enable/disable features per environment
Network Configuration: Timeout settings for API calls
Debug Utilities: Tools for inspecting configuration

Architecture

The configuration system consists of two main classes:

EnvConfig (lib/core/config/env_config.dart): Low-level environment variable loader
- Loads from .env files using flutter_dotenv
- Reads from --dart-define flags
- Provides fallback chain: .env → --dart-define → defaults
AppConfig (lib/core/config/app_config.dart): High-level application configuration
- Uses EnvConfig to get values
- Provides typed getters (String, bool, int)
- Environment-aware defaults
- Feature flags
- Network timeout configuration
- Debug utilities

Setup

1. Create `.env` file for local development

# Copy the example file
cp .env.example .env

# Edit .env with your values
# The .env file is gitignored and won't be committed

2. Configure your environment variables

Edit .env with your configuration:

ENVIRONMENT=development
BASE_URL=http://localhost:3000
ENABLE_LOGGING=true
ENABLE_ANALYTICS=false

Usage Examples

Local Development (using `.env` file)

Create .env file from .env.example
Fill in your values
Run the app normally:

flutter run

The app will automatically load values from .env.

Staging Build (using `--dart-define`)

For CI/CD or when you don't want to use .env files:

flutter run \
  --dart-define=ENVIRONMENT=staging \
  --dart-define=BASE_URL=https://api-staging.example.com \
  --dart-define=ENABLE_ANALYTICS=true

Production Build (using `--dart-define`)

flutter build apk \
  --dart-define=ENVIRONMENT=production \
  --dart-define=BASE_URL=https://api.example.com \
  --dart-define=ENABLE_ANALYTICS=true \
  --dart-define=ENABLE_CRASH_REPORTING=true

Using Configuration in Code

Basic Usage

import 'package:grex/core/config/app_config.dart';

// Get environment
final env = AppConfig.environment; // 'development', 'staging', or 'production'

// Check environment
if (AppConfig.isDevelopment) {
  // Development-specific code
}

// Get API base URL
final baseUrl = AppConfig.baseUrl;

// Check feature flags
if (AppConfig.enableLogging) {
  logger.info('App started');
}

if (AppConfig.enableAnalytics) {
  analytics.trackEvent('app_opened');
}

Network Configuration

import 'package:grex/core/config/app_config.dart';
import 'package:dio/dio.dart';

final dio = Dio(
  BaseOptions(
    baseUrl: AppConfig.baseUrl,
    connectTimeout: Duration(seconds: AppConfig.apiConnectTimeout),
    receiveTimeout: Duration(seconds: AppConfig.apiReceiveTimeout),
    sendTimeout: Duration(seconds: AppConfig.apiSendTimeout),
  ),
);

Debug Utilities

import 'package:grex/core/config/app_config.dart';

// Print configuration to console (only in debug mode)
AppConfig.printConfig();

// Get configuration as a map
final config = AppConfig.getDebugInfo();
print(config);

Available Configuration Options

Environment Variables

Variable	Type	Default	Description
`ENVIRONMENT`	String	`development`	Environment name: `development`, `staging`, or `production`
`BASE_URL`	String	Environment-aware	API base URL (see defaults below)
`API_TIMEOUT`	int	`30`	API timeout in seconds
`API_CONNECT_TIMEOUT`	int	`10`	API connect timeout in seconds
`API_RECEIVE_TIMEOUT`	int	`30`	API receive timeout in seconds
`API_SEND_TIMEOUT`	int	`30`	API send timeout in seconds
`ENABLE_LOGGING`	bool	Environment-aware	Enable logging (default: true in dev/staging)
`ENABLE_ANALYTICS`	bool	Environment-aware	Enable analytics (default: true in staging/prod)
`ENABLE_CRASH_REPORTING`	bool	Environment-aware	Enable crash reporting (default: true in staging/prod)
`ENABLE_PERFORMANCE_MONITORING`	bool	Environment-aware	Enable performance monitoring (default: true in staging/prod)
`ENABLE_DEBUG_FEATURES`	bool	Environment-aware	Enable debug features (default: true in dev)
`ENABLE_HTTP_LOGGING`	bool	Environment-aware	Enable HTTP request/response logging (default: true in dev)
`APP_VERSION`	String	`0.0.1`	App version
`APP_BUILD_NUMBER`	String	`1`	App build number

Environment-Aware Defaults

BASE_URL defaults:

Development: http://localhost:3000
Staging: https://api-staging.example.com
Production: https://api.example.com

Feature Flag defaults:

Logging: Enabled in development and staging
Analytics: Enabled in staging and production
Crash Reporting: Enabled in staging and production
Performance Monitoring: Enabled in staging and production
Debug Features: Enabled in development only
HTTP Logging: Enabled in development only

Best Practices

Never commit .env files: They contain sensitive information and are gitignored
Use .env.example as a template: Commit this file with placeholder values
Use .env for local development: Easy to change values without rebuilding
Use --dart-define for CI/CD: More secure and doesn't require file management
Set environment-specific defaults: Let the system handle defaults based on environment
Use feature flags: Enable/disable features per environment without code changes

Troubleshooting

Configuration not loading

Ensure EnvConfig.load() is called in main() before runApp()
Check that .env file exists in the project root
Verify pubspec.yaml includes .env in assets
Run flutter pub get after adding flutter_dotenv

Values not updating

Hot reload doesn't reload environment variables - do a full restart
For --dart-define values, rebuild the app
Check that you're using the correct variable name (case-sensitive)

Debug configuration

Use AppConfig.printConfig() in debug mode to see all configuration values:

if (AppConfig.isDebugMode) {
  AppConfig.printConfig();
}

This will print all configuration values to the console, helping you verify what values are being used.
