# Google Navigation Flutter Setup Guide
|
||||
|
||||
This document provides detailed instructions for completing the Google Navigation Flutter implementation.
|
||||
|
||||
## Overview
|
||||
|
||||
The implementation includes:
|
||||
- Location permissions handling with user dialogs
|
||||
- Google Navigation session management
|
||||
- Turn-by-turn navigation for delivery destinations
|
||||
- Terms and Conditions acceptance for navigation services
|
||||
- i18n support (English/French)
|
||||
- Proper error handling and logging
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Before implementing, you need:
|
||||
|
||||
1. **Google Cloud Project** with Navigation SDK enabled
|
||||
2. **API Keys** for both Android and iOS platforms
|
||||
3. **Configuration** in Android and iOS native files
|
||||
|
||||
## Part 1: API Key Configuration
|
||||
|
||||
### Android Setup
|
||||
|
||||
1. Open `android/app/build.gradle.kts`
|
||||
2. Add your Android API key to the metadata section in `AndroidManifest.xml`:
|
||||
|
||||
```xml
|
||||
<application>
|
||||
<meta-data
|
||||
android:name="com.google.android.geo.API_KEY"
|
||||
android:value="YOUR_ANDROID_API_KEY" />
|
||||
</application>
|
||||
```
|
||||
|
||||
Alternatively, use Secrets Gradle Plugin for better security:
|
||||
|
||||
```gradle
|
||||
// In android/app/build.gradle.kts
|
||||
android {
|
||||
buildTypes {
|
||||
debug {
|
||||
manifestPlaceholders = [googleMapsApiKey: "YOUR_ANDROID_API_KEY"]
|
||||
}
|
||||
release {
|
||||
manifestPlaceholders = [googleMapsApiKey: "YOUR_ANDROID_API_KEY_RELEASE"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Then in `AndroidManifest.xml`:
|
||||
```xml
|
||||
<meta-data
|
||||
android:name="com.google.android.geo.API_KEY"
|
||||
android:value="${googleMapsApiKey}" />
|
||||
```
|
||||
|
||||
### iOS Setup
|
||||
|
||||
1. Open `ios/Runner/AppDelegate.swift`
|
||||
2. The API key is already configured in the `provideAPIKey()` method:
|
||||
|
||||
```swift
|
||||
import GoogleMaps
|
||||
|
||||
@main
|
||||
@objc class AppDelegate: FlutterAppDelegate {
|
||||
override func application(
|
||||
_ application: UIApplication,
|
||||
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
|
||||
) -> Bool {
|
||||
GMSServices.provideAPIKey("YOUR_IOS_API_KEY")
|
||||
GeneratedPluginRegistrant.register(with: self)
|
||||
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Replace `YOUR_IOS_API_KEY` with your actual Google Cloud Navigation API key.
|
||||
|
||||
## Part 2: Integration with Deliveries Page
|
||||
|
||||
To add navigation button to deliveries, update `lib/pages/deliveries_page.dart`:
|
||||
|
||||
```dart
|
||||
import '../pages/navigation_page.dart';
|
||||
|
||||
// In your delivery item or action menu:
|
||||
ElevatedButton(
|
||||
onPressed: () {
|
||||
Navigator.of(context).push(
|
||||
MaterialPageRoute(
|
||||
builder: (context) => NavigationPage(
|
||||
delivery: delivery,
|
||||
destinationLatitude: delivery.latitude,
|
||||
destinationLongitude: delivery.longitude,
|
||||
onNavigationComplete: () {
|
||||
// Handle navigation completion
|
||||
// Update delivery status
|
||||
ScaffoldMessenger.of(context).showSnackBar(
|
||||
SnackBar(
|
||||
content: Text(
|
||||
AppLocalizations.of(context)?.navigationArrived ??
|
||||
'Navigation completed',
|
||||
),
|
||||
),
|
||||
);
|
||||
},
|
||||
onNavigationCancelled: () {
|
||||
// Handle cancellation
|
||||
ScaffoldMessenger.of(context).showSnackBar(
|
||||
SnackBar(
|
||||
content: Text(
|
||||
AppLocalizations.of(context)?.cancel ?? 'Navigation cancelled',
|
||||
),
|
||||
),
|
||||
);
|
||||
},
|
||||
),
|
||||
),
|
||||
);
|
||||
},
|
||||
child: Text(AppLocalizations.of(context)?.navigateToAddress ?? 'Navigate'),
|
||||
)
|
||||
```
|
||||
|
||||
## Part 3: Location Permissions
|
||||
|
||||
The app uses the `permission_handler` package for location permissions. Permissions are already configured in:
|
||||
|
||||
- **Android**: `android/app/src/main/AndroidManifest.xml`
|
||||
- Required: `INTERNET`, `ACCESS_FINE_LOCATION`, `ACCESS_COARSE_LOCATION`
|
||||
- Optional background modes for continuous navigation
|
||||
|
||||
- **iOS**: `ios/Runner/Info.plist`
|
||||
- `NSLocationWhenInUseUsageDescription`: When app is active
|
||||
- `NSLocationAlwaysAndWhenInUseUsageDescription`: Always
|
||||
- `NSLocationAlwaysUsageDescription`: Background location
|
||||
- Background mode: "location" enabled
|
||||
|
||||
## Part 4: Available Classes and Services
|
||||
|
||||
### NavigationPage
|
||||
Main UI widget for turn-by-turn navigation.
|
||||
|
||||
```dart

|
||||
delivery: deliveryObject,
|
||||
destinationLatitude: 33.5731,
|
||||
destinationLongitude: -7.5898,
|
||||
onNavigationComplete: () { /* Handle arrival */ },
|
||||
onNavigationCancelled: () { /* Handle cancellation */ },
|
||||
)
|
||||
```
|
||||
|
||||
### LocationPermissionService
|
||||
Handles location permission requests and checks.
|
||||
|
||||
```dart
|
||||
final permissionService = LocationPermissionService();
|
||||
|
||||
// Check current permission status
|
||||
final hasPermission = await permissionService.hasLocationPermission();
|
||||
|
||||
// Request permission
|
||||
final result = await permissionService.requestLocationPermission();
|
||||
result.when(
|
||||
granted: () { /* Permission granted */ },
|
||||
denied: () { /* Permission denied */ },
|
||||
permanentlyDenied: () { /* Need to open settings */ },
|
||||
error: (message) { /* Handle error */ },
|
||||
);
|
||||
```
|
||||
|
||||
### NavigationSessionService

||||
Manages the Google Navigation session lifecycle.
|
||||
|
||||
```dart
|
||||
final sessionService = NavigationSessionService();
|
||||
|
||||
// Initialize session
|
||||
await sessionService.initializeSession();
|
||||
|
||||
// Set controller from the navigation view
|
||||
await sessionService.setController(navigationViewController);
|
||||
|
||||
// Calculate and set route
|
||||
final route = await sessionService.calculateRoute(
|
||||
startLatitude: 33.5731,
|
||||
startLongitude: -7.5898,
|
||||
destinationLatitude: 33.5745,
|
||||
destinationLongitude: -7.5850,
|
||||
);
|
||||
|
||||
// Listen to events
|
||||
sessionService.addArrivalListener((info) {
|
||||
print('Arrived at destination');
|
||||
});
|
||||
|
||||
sessionService.addLocationListener((location) {
|
||||
print('Location: ${location.latitude}, ${location.longitude}');
|
||||
});
|
||||
|
||||
// Start/stop navigation
|
||||
await sessionService.startNavigation();
|
||||
await sessionService.stopNavigation();
|
||||
|
||||
// Cleanup when done
|
||||
await sessionService.cleanup();
|
||||
```
|
||||
|
||||
### NavigationTermsAndConditionsDialog

|
||||
|
||||
```dart
|
||||
showDialog(
|
||||
context: context,
|
||||
builder: (context) => NavigationTermsAndConditionsDialog(
|
||||
onAccept: () {
|
||||
// Save acceptance and proceed with navigation
|
||||
},
|
||||
onDecline: () {
|
||||
// User declined, don't start navigation
|
||||
},
|
||||
),
|
||||
);
|
||||
```
|
||||
|
||||
## Part 5: Error Handling
|
||||
|
||||
The implementation includes comprehensive error handling for:
|
||||
|
||||
1. **Location Permission Errors**
|
||||
- Permission denied
|
||||
- Permission permanently denied
|
||||
- System errors
|
||||
|
||||
2. **Navigation Initialization Errors**
|
||||
- Session initialization failure
|
||||
- Controller not available
|
||||
- Route calculation failure
|
||||
|
||||
3. **Runtime Errors**
|
||||
- Network issues
|
||||
- Location acquisition timeout
|
||||
- Navigation start/stop failures
|
||||
|
||||
All errors are displayed through user-friendly dialogs with action buttons.
|
||||
|
||||
## Part 6: Internationalization
|
||||
|
||||
Navigation strings are available in English and French:
|
||||
- `navigationTcTitle`, `navigationTcDescription`
|
||||
- `locationPermissionRequired`, `locationPermissionMessage`
|
||||
- `navigationArrived`, `navigatingTo`
|
||||
|
||||
Add custom translations to `lib/l10n/app_*.arb` files as needed.
|
||||
|
||||
## Part 7: Testing Checklist
|
||||
|
||||
### Android Testing
|
||||
- [ ] Test on API level 23+ device
|
||||
- [ ] Verify minSdk=23 is set
|
||||
- [ ] Check desugaring is enabled
|
||||
- [ ] Test location permissions request
|
||||
- [ ] Verify navigation starts correctly
|
||||
- [ ] Test with GPS disabled/enabled
|
||||
- [ ] Verify Terms & Conditions dialog shows
|
||||
|
||||
### iOS Testing

### Common Issues and Solutions
|
||||
|
||||
**Issue**: "Navigation SDK not available"
|
||||
- Solution: Verify API key is correctly added and Navigation SDK is enabled in Google Cloud Console
|
||||
|
||||
**Issue**: "Location permission always denied"
|
||||
- Solution: Clear app data and reinstall, or open app settings and manually enable location
|
||||
|
||||
**Issue**: "Navigation session fails to initialize"
|
||||
- Solution: Check that controller is properly created before calling methods
|
||||
|
||||
**Issue**: "Routes not calculating"
|
||||
- Solution: Ensure start and destination coordinates are valid and within service areas
|
||||
|
||||
## Part 8: Production Considerations
|
||||
|
||||
Before releasing to production:
|
||||
|
||||
1. **API Key Security**
|
||||
- Use separate API keys for Android and iOS
|
||||
- Restrict API keys by platform and package name
|
||||
- Rotate keys periodically
|
||||
|
||||
2. **Analytics**
|
||||
- Track navigation start/completion rates
|
||||
- Monitor location permission denial rates
|
||||
- Log any navigation errors
|
||||
|
||||
3. **User Experience**
|
||||
- Provide clear instructions for permission requests
|
||||
- Show progress during initialization
|
||||
- Handle network failures gracefully
|
||||
|
||||
4. **Compliance**
|
||||
- Ensure proper attribution to Google
|
||||
- Display Terms & Conditions for navigation
|
||||
- Comply with EEA data regulations if applicable
|
||||

- iOS: Update AppDelegate.swift (already configured)
|
||||
|
||||
2. **Update AndroidManifest.xml** (if not using build.gradle)
|
||||
```xml
|
||||
<meta-data
|
||||
android:name="com.google.android.geo.API_KEY"
|
||||
android:value="YOUR_API_KEY" />
|
||||
```
|
||||
|
||||
3. **Verify Permissions** in AndroidManifest.xml
|
||||
- `INTERNET`
|
||||
- `ACCESS_FINE_LOCATION`
|
||||
- `ACCESS_COARSE_LOCATION`
|
||||
|
||||
4. **Test on Devices**
|
||||
- Android 6.0+ (API 23+)
|
||||
- iOS 16.0+
|
||||
- Real devices (emulator may have limited GPS)
|
||||
|
||||
## Design System Compliance
|
||||
|
||||
All components follow Svrnty design system:
|
||||
- Material 3 theme colors (Primary: #C44D58, Secondary: #475C6C)
|
||||
- Montserrat typography
|
||||
- Dark/light theme support
|
||||
- High contrast variants compatible
|
||||
|
||||
## Code Quality
|
||||
|
||||
- Strict typing enforced (no `dynamic` or untyped `var`)
|
||||
- Sealed classes for type-safe pattern matching
|
||||
- Result pattern for error handling
|
||||
- Proper resource cleanup in dispose
|
||||
- Comprehensive null safety
|
||||
|
||||
## Testing Recommendations
|
||||
|
||||
### Android
|
||||
- Test on API 23+ device
|
||||
- Verify GPS works
|
||||
- Check location permission dialog
|
||||
- Verify navigation UI displays correctly
|
||||
- Test arrival notifications
|
||||
|
||||
### iOS
|
||||
- Test on iOS 16.0+ device
|
||||
- Verify location permission dialog
|
||||
- Check background location mode
|
||||
- Test with navigation UI
|
||||
- Verify arrival notification
|
||||
|
||||
## Known Limitations
|
||||
|
||||
- Package is in Beta (expect potential breaking changes)
|
||||
- Don't combine with other Google Maps SDK versions
|
||||
- EEA developers subject to regional terms (effective July 8, 2025)
|
||||
- Navigation requires actual GPS for best results
|
||||
|
||||
## Documentation
|
||||
|
||||
Comprehensive setup guide provided in `GOOGLE_NAVIGATION_SETUP.md` including:
|
||||
- API key configuration for both platforms
|
||||
- Integration examples
|
||||
- Service usage documentation
|
||||
- Error handling patterns
|
||||
- Production considerations
|
||||
- Testing checklist
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. Add your Google Cloud API keys
|
||||
2. Test location permissions flow
|
||||
3. Integrate navigation button into delivery items
|
||||
4. Test on real Android and iOS devices
|
||||
5. Monitor navigation start/completion rates
|
||||
6. Gather user feedback on navigation experience
