3-4: Consider enhancing the changelog entries for better clarity.While the changes are documented, the entries could be more specific to help users understand the impact:
-* Modified Regex for handling negative latitude, longitude and added new accuracy field -* Added new accuracy field to fetch precise location +* Modified Regex to properly handle negative values in latitude and longitude coordinates +* Added a new accuracy field to improve location precision tracking (in meters)🧰 Tools

33-33: Consider making accuracy pattern consistent with lat/long pattern.While the regex correctly handles negative values for latitude and longitude, the accuracy pattern
(\d+\.\d+)only accepts positive values. For consistency and future-proofing, consider using the same pattern(-?\d+\.\d+)for accuracy as well.- r'Latitude:\s*(-?\d+\.\d+),\s*Longitude:\s*(-?\d+\.\d+),\s*Accuracy:\s*(\d+\.\d+),\s*isSync:\s*(\w+),\s*timestamp:\s*(\d+)'); + r'Latitude:\s*(-?\d+\.\d+),\s*Longitude:\s*(-?\d+\.\d+),\s*Accuracy:\s*(-?\d+\.\d+),\s*isSync:\s*(\w+),\s*timestamp:\s*(\d+)');apps/health_campaign_field_worker_app/android/app/src/main/kotlin/com/digit/hcm/MainActivity.kt (2)
23-24: Enhance robustness of accuracy handlingConsider these improvements:
- Add null safety check for the intent
- Use a more meaningful default value (e.g., -1.0f) to distinguish invalid/unavailable accuracy
- val accuracy = intent?.getFloatExtra("accuracy", 0.0f) // Retrieve accuracy here + if (intent == null) { + return + } + val accuracy = intent.getFloatExtra("accuracy", -1.0f) // -1 indicates invalid/unavailable accuracy
Line range hint
1-94: Consider extracting location-related constantsFor better maintainability and consistency, consider extracting location-related constants (channel name, intent extras) into a companion object or constants file.
companion object { private const val LOCATION_CHANNEL = "com.digit.location_tracker" private const val EXTRA_LATITUDE = "latitude" private const val EXTRA_LONGITUDE = "longitude" private const val EXTRA_ACCURACY = "accuracy" }apps/health_campaign_field_worker_app/android/app/src/main/kotlin/com/digit/hcm/location_service.kt (1)
133-134: Consider formatting the notification for better readabilityWhile adding accuracy is valuable, the notification text might get truncated on some devices. Consider a more concise format or multiple lines.
- val notificationContent = "Latitude: ${location.latitude}, Longitude: ${location.longitude}, Accuracy: ${location.accuracy}" + val notificationContent = "Location: (${location.latitude}, ${location.longitude})\nAccuracy: ${location.accuracy}m"

1-2: LGTM! Version numbering follows semantic versioning.
The dev version increment is appropriate for these feature additions and improvements.

26-26: Consider limiting location Toast to debug builds
The Toast message displays precise location data which might be sensitive information. Consider wrapping this in a debug-only block.
[security]
- Toast.makeText(context, "Latitude: $latitude, Longitude: $longitude, Accuracy: $accuracy", Toast.LENGTH_LONG).show()
+ if (BuildConfig.DEBUG) {
+ Toast.makeText(context, "Latitude: $latitude, Longitude: $longitude, Accuracy: $accuracy", Toast.LENGTH_LONG).show()
+ }29-33: 🛠️ Refactor suggestion
Add validation for location values
As per PR objectives, the code should handle negative values for latitude, longitude, and accuracy. Consider adding validation before sending the data to Flutter.
Let's verify if the Flutter side is ready to handle these values:
MethodChannel(it, CHANNEL).invokeMethod("locationUpdate", mapOf(
- "latitude" to latitude,
- "longitude" to longitude,
- "accuracy" to accuracy
+ "latitude" to (latitude ?: 0.0),
+ "longitude" to (longitude ?: 0.0),
+ "accuracy" to (if (accuracy != null && accuracy >= 0) accuracy else null)
))apps/health_campaign_field_worker_app/android/app/src/main/kotlin/com/digit/hcm/location_service.kt (2)
95-95: LGTM: Location accuracy properly integrated
The accuracy value is correctly added to the intent extras and logged, which aligns with the PR objectives for enhanced location tracking.
Also applies to: 99-99
94-100: 🛠️ Refactor suggestion
Verify: Missing validation for negative coordinates
The PR objectives mentioned handling negative values for latitude and longitude, but there's no validation logic implemented. Consider adding appropriate validation:
#!/bin/bash
# Check if there's any coordinate validation in the codebase
# Look for coordinate validation patterns
rg "latitude.*(-|negative)|longitude.*(-|negative)"
# Check for any existing validation utils
ast-grep --pattern 'fun $_(latitude: Double, longitude: Double)' -A 5 private fun sendLocationToMainActivity(location: Location) {
+ // Validate coordinates
+ if (!isValidCoordinate(location.latitude, location.longitude)) {
+ Log.e("LocationService", "Invalid coordinates: ${location.latitude}, ${location.longitude}")
+ return
+ }
val intent = Intent("LocationUpdate")
intent.putExtra("latitude", location.latitude)
intent.putExtra("longitude", location.longitude)
intent.putExtra("accuracy", location.accuracy)

30-52: Refactor complex boolean logic into helper methodsThe module and code filtering logic is complex and could benefit from being extracted into separate helper methods for better maintainability and testability.
Consider refactoring like this:
Expression<bool> buildModuleCondition(LocalSqlDataStore sql, String moduleToExclude, bool exclude) { return exclude ? sql.localization.module.contains(moduleToExclude).not() : sql.localization.module.contains(moduleToExclude); } Expression<bool> buildCodeCondition(LocalSqlDataStore sql, Set<String>? codes) { return codes?.isNotEmpty == true ? sql.localization.code.isIn(codes.toList()) : const Constant(false); }

86-90: Review the OR condition logic
The current OR condition between locale and module might return more results than expected. Consider if an AND condition would be more appropriate for filtering.
#!/bin/bash
# Check for similar query patterns in the codebase
ast-grep --pattern 'buildOr([
$$$
])'13-13: Document and verify retryLocalCallOperation implementation
The new error handling wrapper retryLocalCallOperation has been added to all repository methods, but its implementation details are not visible in this file.
#!/bin/bash
# Look for the implementation of retryLocalCallOperation
rg -p "retryLocalCallOperation" --type dart
# Check for similar retry patterns in the codebase
ast-grep --pattern 'retryLocalCallOperation($$$)'Please ensure that:
- The retry mechanism has configurable parameters (max attempts, delay)
- It handles specific SQL exceptions appropriately
- It includes logging for debugging purposes
Also applies to: 83-83, 107-107
20-23: 🛠️ Refactor suggestion
Add input validation for LocalizationParams
The direct access to LocalizationParams() without validation could lead to runtime issues. Consider adding null checks and validation at the method entry point.
+ if (LocalizationParams().locale?.isEmpty ?? true) {
+ throw ArgumentError('Locale must not be empty');
+ }
if (LocalizationParams().locale != null) {
- final localeString = '${LocalizationParams().locale!}';
+ final localeString = LocalizationParams().locale!;
andConditions.add(sql.localization.locale.equals(localeString));
}| return retryLocalCallOperation(() async { | ||
| return sql.batch((batch) { | ||
| batch.insertAll(sql.localization, result); | ||
| }); |

🛠️ Refactor suggestion
Add batch size limit and duplicate handling
The batch insert operation should include:
- A maximum batch size to prevent memory issues
- A strategy for handling duplicate entries (e.g., IGNORE or REPLACE)
return retryLocalCallOperation(() async {
+ const int maxBatchSize = 1000;
+ for (var i = 0; i < result.length; i += maxBatchSize) {
+ final end = (i + maxBatchSize < result.length) ? i + maxBatchSize : result.length;
return sql.batch((batch) {
- batch.insertAll(sql.localization, result);
+ batch.insertAll(
+ sql.localization,
+ result.sublist(i, end),
+ mode: InsertMode.insertOrReplace,
+ );
});
+ }
