Korken Mosaic (Flutter MVP)

Prototype Flutter app for generating bottle-cap mosaics from imported images.

Implemented MVP

• Import target image from gallery (image_picker)
• Resolution controls:
  • explicit grid width/height
  • or auto grid by approximate cap size in source image pixels
• Cap palette management:
  • list caps with name + color
  • add color via picker and/or manual hex
  • remove caps
• Mosaic generation:
  • resize source to grid
  • nearest cap color match using CIELAB + DeltaE (CIE76)
  • fallback concept is RGB distance, but LAB path is implemented directly
• Output:
  • mosaic grid preview
  • bill of materials counts per cap color

Current blocker on this machine

flutter SDK is not installed (flutter: command not found), so I could not run:

• flutter create
• flutter pub get
• flutter analyze
• flutter build apk --debug

Setup commands (Ubuntu/Debian)

cd /home/yadciel/.openclaw/workspace
sudo snap install flutter --classic
# OR: install manually from flutter.dev and add to PATH

flutter doctor

cd /home/yadciel/.openclaw/workspace/korken_mosaic
flutter create .
flutter pub get
flutter run
flutter build apk --debug

Expected APK artifact:

build/app/outputs/flutter-apk/app-debug.apk
