+
+Draw SVG files using Flutter.
+
+## Getting Started
+
+Basic usage (to create an SVG rendering widget from an asset):
+
+```dart
+final String assetName = 'assets/image.svg';
+final Widget svg = SvgPicture.asset(
+  assetName,
+  semanticsLabel: 'Acme Logo'
+);
+```
+
+You can color/tint the image like so:
+
+```dart
+final String assetName = 'assets/up_arrow.svg';
+final Widget svgIcon = SvgPicture.asset(
+  assetName,
+  colorFilter: ColorFilter.mode(Colors.red, BlendMode.srcIn),
+  semanticsLabel: 'A red up arrow'
+);
+```
+
+The default placeholder is an empty box (`LimitedBox`) - although if a `height`
+or `width` is specified on the `SvgPicture`, a `SizedBox` will be used instead
+(which ensures better layout experience). There is currently no way to show an
+Error visually, however errors will get properly logged to the console in debug
+mode.
+
+You can also specify a placeholder widget. The placeholder will display during
+parsing/loading (normally only relevant for network access).
+
+```dart
+// Will print error messages to the console.
+final String assetName = 'assets/image_that_does_not_exist.svg';
+final Widget svg = SvgPicture.asset(
+  assetName,
+);
+
+final Widget networkSvg = SvgPicture.network(
+  'https://site-that-takes-a-while.com/image.svg',
+  semanticsLabel: 'A shark?!',
+  placeholderBuilder: (BuildContext context) => Container(
+      padding: const EdgeInsets.all(30.0),
+      child: const CircularProgressIndicator()),
+);
+```
+
+If you'd like to render the SVG to some other canvas, you can do something like:
+
+```dart
+import 'package:flutter_svg/flutter_svg.dart';
+final String rawSvg = '''<svg ...>...</svg>''';
+final PictureInfo pictureInfo = await vg.loadPicture(SvgStringLoader(rawSvg), null);
+
+// You can draw the picture to a canvas:
+canvas.drawPicture(pictureInfo.picture);
+
+// Or convert the picture to an image:
+final ui.Image image = pictureInfo.picture.toImage(...);
+
+pictureInfo.picture.dispose();
+```
+
+The `SvgPicture` helps to automate this logic, and it provides some convenience
+wrappers for getting assets from multiple sources. Unlike the `vector_graphics`
+package, this package _does not render the data to an `Image` at any point_.
+This carries a performance penalty for some common use cases, but also allows
+for more flexibility around scaling.
+
+## Precompiling and Optimizing SVGs
+
+The vector_graphics backend supports SVG compilation which produces a binary
+format that is faster to parse and can optimize SVGs to reduce the amount of
+clipping, masking, and overdraw. The SVG compilation is provided by
+[`package:vector_graphics_compiler`](https://pub.dev/packages/vector_graphics_compiler).
+
+```sh
+dart run vector_graphics_compiler -i assets/foo.svg -o assets/foo.svg.vec
+```
+
+The output `foo.svg.vec` can be loaded using the default constructor of
+`SvgPicture`.
+
+```dart
+import 'package:flutter_svg/flutter_svg.dart';
+import 'package:vector_graphics/vector_graphics.dart';
+
+final Widget svg = SvgPicture(
+  const AssetBytesLoader('assets/foo.svg.vec')
+);
+```
+
+### Check SVG compatibility
+
+An SVG can be tested for compatibility with the vector graphics backend by
+running the compiler locally to see if any errors are thrown.
+
+```sh
+dart run vector_graphics_compiler -i $SVG_FILE -o $TEMPORARY_OUTPUT_TO_BE_DELETED --no-optimize-masks --no-optimize-clips --no-optimize-overdraw --no-tessellate
+```
+
+## Recommended Adobe Illustrator SVG Configuration
+- In Styling: choose Presentation Attributes instead of Inline CSS because CSS is not fully supported.
+- In Images: choose Embded not Linked to other file to get a single svg with no dependency to other files.
+- In Objects IDs: choose layer names to add every layer name to svg tags or you can use minimal,it is optional.

+## SVG sample attribution
+
+SVGs in `/assets/w3samples` pulled from [W3 sample files](https://dev.w3.org/SVG/tools/svgweb/samples/svg-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. Some
+have also come or been adapted from issues raised in this repository.
+
+SVGs in `/assets/wikimedia` are pulled from [Wikimedia Commons](https://commons.wikimedia.org/wiki/Main_Page)
+
+Android Drawables in `/assets/android_vd` are pulled from Android Documentation
+and examples.
+
+The Flutter Logo created based on the Flutter Logo Widget © Google.
+
+The Dart logo is from
+[dartlang.org](https://github.com/dart-lang/site-shared/blob/master/src/_assets/images/dart/logo%2Btext/horizontal/original.svg)
+© Google
+
+SVGs in `/assets/noto-emoji` are from [Google i18n noto-emoji](https://github.com/googlei18n/noto-emoji),
+licensed under the Apache license.
+
+Please submit SVGs that 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).
