modifyRecommendations method

Future<GeminiResponse?> modifyRecommendations(String originalInput, String? architecture, String modifications, GeminiResponse currentResponse,)

Regenerate recommendations with user modifications

Implementation

Future<GeminiResponse?> modifyRecommendations(
  String originalInput,
  String? architecture,
  String modifications,
  GeminiResponse currentResponse,
) async {
  if (_apiKey.isEmpty) {
    print('   ❌ API key not configured');
    return null;
  }

  try {
    final prompt =
        '''You are a Flutter architecture expert. The user wants to modify their project recommendations.

ORIGINAL PROJECT: "$originalInput"
${architecture != null ? 'ARCHITECTURE: $architecture (USER REQUESTED)' : ''}

CURRENT RECOMMENDATIONS:
- Packages (${currentResponse.packages.length}): ${currentResponse.packages.join(', ')}
- Architecture: ${currentResponse.folderStructure.pattern}
- Folders: ${currentResponse.folderStructure.folders.join(', ')}

USER REQUESTED CHANGES: "$modifications"

Apply the requested changes and return ONLY valid JSON with this EXACT structure:
{
"packages": ["package1", "package2"],
"appFlow": ["Screen1", "Screen2"],
"folderStructure": {
  "pattern": "architecture-name",
  "folders": ["folder/path1", "folder/path2"]
},
"notes": "Brief guidance about changes made"
}

CRITICAL:
- Keep what the user didn't ask to change
- Add/remove/replace only what was requested
- Ensure all packages exist on pub.dev
- Maintain architecture consistency
- If unclear, interpret intelligently

Examples of changes:
- "add payment integration" → add razorpay_flutter, flutter_stripe
- "remove firebase" → remove all firebase_* packages
- "add maps" → add google_maps_flutter, geolocator
- "use bloc instead" → replace provider with flutter_bloc, bloc
- "add more folders for features" → add feature-specific folders
