Build Status

Draw SVG and Android VectorDrawable (XML) files on a Flutter Widget.

Getting Started

This is a Dart-native rendering library. Issues/PRs will be raised in Flutter and flutter/engine as necessary for features that are not good candidates for Dart implementations (especially if they're impossible to implement without engine support). However, not everything that Skia can easily do needs to be done by Skia; for example, the Path parsing logic here isn't much slower than doing it in native, and Skia isn't always doing low level GPU accelerated work where you might think it is (e.g. Dash Paths).

Basic usage (to create an SVG rendering widget from an asset):

final String assetName = 'assets/image.svg';
final Widget svg = new SvgImage.asset(
  assetName,
  new Size(100.0, 100.0),
);

See main.dart for a complete sample.

TODO

This list is roughly ordered.

  • Text support
  • Gradient support (Linear: Mostly done, Radial: partly done)
  • Dash path support
  • More SVG samples to cover more complicated cases
  • Display/visibility support
  • Unit tests
  • Inerhitance of inheritable properties (necessary? preprocess?)
  • Support for minimal CSS/styles? See also svgcleaner
  • XLink/ref support (necessary? partially supported for gradients)
  • Glyph support?
  • Markers
  • Filters/effects
  • Android Vector Drawable support (partial so far)
  • Caching of image

Probably out of scope

  • SMIL animations. That just seems crazy.
  • Full (any?) CSS support - preprocess your SVGs (perhaps with svgcleaner to get rid of all CSS?)
  • Scripting in SVGs
  • Foreign elements
  • Rendering properties/hints

SVG sample attribution

SVGs in /assets/w3samples pulled from W3 sample files

SVGs in /assets/deborah_ufw provided by @deborah-ufw

SVGs in /assets/simple are pulled from trivial examples or generated to test basic functionality - some of them come directly from the SVG 1.1 spec.

SVGs in /assets/wikimedia are pulled from Wikimedia Commons

Android Drawables in assets/android_vd are pulled from Android Documentation and examples.

The Flutter Logo created based on the Flutter Logo Widget.

Please submit SVGs this can't render properly (e.g. that don't render here the way they do in chrome), as long as they're not using anything "probably out of scope" (above).
