Packr – Carton Packing App

A Flutter app designed to help calculate smarter carton packing combinations, compare packing modes, and visualize packing results.

Problem

Packing different products into cartons can be difficult when dimensions, quantities, orientation, and practical packing limitations need to be considered.

Solution

I built Packr to calculate packing options, support different packing modes, store carton presets, and make results easier to understand visually.

Key Features

  • Multi-product carton packing
  • Maximum-fit calculation mode
  • Human packing mode
  • Saved carton presets
  • 3D visualization
  • Fill percentage and volume usage metrics
