vector_graphics

A vector graphics rendering runtime for Flutter. This package is intended for use with output from the package:vector_graphics_compiler and encoded via a tightly coupled version of package:vector_graphics_codec.

Commemoration

This package was originally authored by Dan Field and has been forked here from dnfield/vector_graphics. Dan was a member of the Flutter team at Google from 2018 until his death in 2024. Dan’s impact and contributions to Flutter were immeasurable, and we honor his memory by continuing to publish and maintain this package.
