GatorConfig.fromYaml constructor

GatorConfig.fromYaml(YamlMap yamlDoc)

The configuration that represents the YAML document.

Example yaml:

gator:
  class: MyColors
  colors:
    royalBlue: '0xff062091'
    grey: '#ffd6d6d6'

There the gator and colors entries are required from the YAML document.

Implementation

factory GatorConfig.fromYaml(YamlMap yamlDoc) {
  assert(
    yamlDoc['gator'] != null,
    '''
A "gator" entry must be specified.
Example:

```yaml
gator:
class: MyColors
output: example/colors.g.dart
colors:
  royalBlue: '0xff062091'
  grey: '#d6d6d6'
  rebeccaPurple: '663399'```
''',
  );

  final shaderConfig = yamlDoc['gator'] as YamlMap;
  final yamlColors = shaderConfig['colors'] as YamlMap;
  final className = shaderConfig['class'] as String?;
  final outputPath = shaderConfig['output'] as String?;
  final decodedColors = yamlColors.keys.cast<String>().map<ConfigColor>(
        (String color) => ConfigColor.fromHex(
          hex: yamlColors[color] as String,
          name: color,
        ),
      );

  return GatorConfig._(
    outputPath: outputPath,
    colors: decodedColors,
    className: className ?? 'MyColors',
  );
}
