## 🎯 Pre-filled Test Credentials

The login form is pre-filled with test credentials:
- **Email**: `yesterday305@gmail.com`
- **Password**: `123456`

## 🚀 Ready to Test

The app is now configured to connect to the actual backend API. You can:

1. **Run the app**:
   ```bash
   flutter run
   ```

2. **Test the flow**:
   - Login with pre-filled credentials
   - View warehouses list
   - Select a warehouse
   - Choose Import or Export
   - View products

## 📝 API Request Examples

### Login Request:
```bash
POST https://dotnet.elidev.info:8157/ws/PortalAuth/Login
Headers:
  Content-Type: application/json
  AppID: Minhthu2016
Body:
{
  "EmailPhone": "yesterday305@gmail.com",
  "Password": "123456"
}
```

### Get Warehouses Request:
```bash
POST https://dotnet.elidev.info:8157/ws/portalWareHouse/search
Headers:
  Content-Type: application/json
  AppID: Minhthu2016
  AccessToken: {token_from_login}
Body:

## ⚠️ Important Notes

1. **HTTPS Certificate**: The API uses a self-signed certificate. You may need to handle SSL certificate validation in production.

2. **CORS**: Make sure CORS is properly configured on the backend for mobile apps.

3. **Token Storage**: Access tokens are securely stored using `flutter_secure_storage`.

4. **Error Handling**: All API errors are properly handled and displayed to users.

5. **Logging**: API requests and responses are logged in debug mode for troubleshooting.

## 🔍 Testing Checklist

- [ ] Login with test credentials works
- [ ] Access token is saved in secure storage
- [ ] Warehouses list loads successfully
- [ ] Warehouse selection works
- [ ] Navigation to operations page works
- [ ] Products list loads successfully
- [ ] All UI states work (loading, error, success, empty)
- [ ] Refresh functionality works
- [ ] Logout clears the token

## 🐛 Troubleshooting

### If login fails:
1. Check internet connection
2. Verify API is accessible at `https://dotnet.elidev.info:8157`
3. Check credentials are correct
4. Look at debug logs for detailed error messages

### If API calls fail after login:
1. Verify access token is being saved
2. Check that AccessToken and AppID headers are being sent
3. Verify token hasn't expired
4. Check API logs for detailed error information
