decodeCornerStrategy static method

CornerStrategy? decodeCornerStrategy(
  1. dynamic map, {
  2. bool validate = true,
})

Decodes the object from an int or Map-like dynamic structure. This expects the JSON format to be of the following structure:

{
  "type": "none"
}

{
  "radius": <int>,
  "type": "const"
}

Implementation

static charts.CornerStrategy? decodeCornerStrategy(
  dynamic map, {
  bool validate = true,
}) {
  charts.CornerStrategy? result;

  if (map is charts.CornerStrategy) {
    result = map;
  } else if (map is num) {
    result = charts.ConstCornerStrategy(map.toInt());
  } else if (map != null) {
    assert(SchemaValidator.validate(
      schemaId: '$_baseSchemaUrl/corner_strategy',
      value: map,
      validate: validate,
    ));
    final type = map['type'];

    switch (type) {
      case 'const':
        result =
            charts.ConstCornerStrategy(JsonClass.parseInt(map['radius'])!);
        break;

      case 'none':
        result = const charts.NoCornerStrategy();
        break;

      default:
        throw Exception('Unknown [CornerStrategy.type] encountered: [$type]');
    }
  }

  return result;
}
