by Flutter Awesome

If you’re like me, you love discovering little Flutter gems that push the boundaries of what’s possible. Today I want to share something that blends creativity, design, and Flutter’s rendering power: Paper Heatmap Logo.

This open source demo takes your logo and transforms it into a heatmap-style visualization—a glowing, colorful effect inspired by the Make your logo in the heat map style demo from the Paper team.

The secret sauce? Shaders and colors pulled directly from the paper-design/shaders
repository. By plugging these into Flutter’s rendering pipeline, you can turn ordinary shapes into vibrant, dynamic logos that feel alive.
