vector_graphics_compiler

A compiler for package:vector_graphics.

This package parses SVG files into a format that the vector_graphics runtime can render.

Features

Supported SVG features:

  • Groups, paths, and basic shapes are all supported.
  • References, including out of order references.
  • Linear and radial gradients, including radial gradients with focal points.
  • Text
  • Symbols
  • Images
  • Patterns

Unsupported SVG features:

  • Filters
  • Some text processing attributes

Optimizations:

  • Opacity peepholing
  • Transformation inlining (except for text and radial gradients)
  • Group collapsing
  • Mask and clip elimination

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.

История изменений

1.2.3

  • Fixes the SVG parser injecting a spurious space between adjacent <tspan> elements that have no whitespace between them in the source. Previously <tspan>A</tspan><tspan>B</tspan> was emitted as "A" + " B", producing a visible gap; it now emits "A" + "B" to match every browser.

1.2.2

  • Adds support for modern space-separated HSL and HSLA color syntax.

1.2.1

  • Fixes HSL/HSLA color parsing for decimal percentage components (e.g. hsl(270, 100%, 76.27%)).

1.2.0

  • Adds support for percentage units in SVG shape attributes (rect, circle, ellipse, line).

1.1.20

  • Fixes color parsing for modern rgb and rgba CSS syntax.
  • Updates minimum supported SDK version to Flutter 3.35/Dart 3.9.

1.1.19

  • Updates allowed version range of xml to include up to 6.6.1.
  • Updates minimum supported SDK version to Flutter 3.29/Dart 3.7.

1.1.18

  • Updates minimum supported SDK version to Flutter 3.27/Dart 3.6.
  • Fixes SVG matrix parsing to explicitly set the Z scale value.

1.1.17

  • Fixes a bug where stroke opacity not applied by color mapper.

1.1.16

  • Sets stroke-width to 1 by default when an invalid value is parsed instead of throwing an exception.

1.1.15

  • Fixes a bug where empty tags caused the parser to crash.

1.1.14

  • Use package:http to drop dependency on dart:html.

1.1.10+1

  • Add missing save before clip.

1.1.10

  • Add missing clip before saveLayer.

1.1.9+2

  • Fix case sensitivity on scientific notation parsing.

1.1.9+1

  • Fix publication error that did not have latest source code.

1.1.9

  • Fix handling of invalid XML @id attributes.
  • Fix handling of self-referential <use/> elements.
  • Add --out-dir option to compiler.
  • Tweak warning message for unhandled eleemnts.

1.1.8

  • Fix bugs in transform parsing.

1.1.7

  • Support for matching the ambient text direction.

1.1.6

  • Fix bug in text position computation when transforms are involved.

1.1.5+1

  • Remove/update some invalid assertions related to image formats.

1.1.5

  • Support for encoding path control points as IEEE 754-2008 half precision floating point values using the option --use-half-precision-control-points.
  • Added an error builder property to provide a fallback widget on exceptions.

1.1.4

  • Support more image formats and malformed MIME types.
  • Fix inheritence for fill-rules.

1.1.3

    • Inheritence of use elements is more correctly handled.
  • Make currentColor non-null on SVG theme, and fix how it is applied.
  • Remove the opacity peephole optimizer, which was incorrectly applying optimizations in a few cases. A future release may add this back.
  • Add clipBehavior to the widget.
  • Fix patterns when multiple patterns are specified and applied within the graphic.
