flutter3d_core #

The engine's rendering core with no Flutter SDK behind it (mcp-03n): scene graph, render list, passes, materials, animation, and model/material loading down to the one call each still needs an injected reader or decoder for.

flutter3d is the thin Flutter shell over this package that most applications actually depend on — BundleAssetSource, defaultImageDecoder, and the widgets. A modeller's document layer, the tool an agent starts with dart run, and a service checking an uploaded asset depend on this package directly instead, since none of them has a window in front of it.
