built_path 0.1.0

Process SVG Path data into Flutter Path objects using build_runner.

Built Path

This library can help Flutter applications pre-compile SVG Path data into Flutter (dart:ui) Path objects.

For example:

import 'package:built_path_annotations/built_path_annotations.dart';

part 'example.svg_path.g.dart';

@SvgPath('M10 10 L20 20 Z')
Path get diagonalLine => _$diagonalLine;

Will generate Dart code like the following:

part of 'example.dart'

Path __$diagonalLine;
Path get _$diagonalLine => __$diagonalLine ??
  (__$diagonalLine = new Path()
                      ..moveTo(10.0, 10.0)
                      ..lineTo(20.0, 20.0)
                      ..close());

Note that for a Flutter project, you'll have to run flutter packages pub run build_runner build. Follow https://github.com/flutter/flutter/issues/13360, as this syntax may change in a future version of Flutter.

Also note that there will be an error reported about dart:ui until https://github.com/dart-lang/build/issues/733 is resolved, but the code should still get generated.

The example/ folder contains a full working example for Flutter, including the build.yaml and generated code.
