decodeStrutStyle static method

StrutStyle? decodeStrutStyle(dynamic value, { bool validate = true, })

Decodes the given value into a StrutStyle. If the value is null then null will be returned. Otherwise, this expects a Map like value that in JSON would look like:

{
  "fontFamily": "<String>",
  "fontFamilyFallback": "<String[]>",
  "fontSize": "<double>",
  "fontStyle": "<FontStyle>",
  "fontWeight": "<FontWeight>"
  "forceStrutHeight": "<bool>",
  "height": "<double>",
  "leading": "<double>",
  "leadingDistribution": "<TextLeadingDistribution>",
  "package": "<String>"
}

Implementation

static StrutStyle? decodeStrutStyle(
  dynamic value, {
  bool validate = true,
}) {
  StrutStyle? result;

  if (value is StrutStyle) {
    result = value;
  } else if (value != null) {
    assert(SchemaValidator.validate(
      schemaId: '$_baseSchemaUrl/strut_style',
      value: value,
      validate: validate,
    ));
    result = StrutStyle(
      fontFamily: value['fontFamily'],
      fontFamilyFallback: _decodeStringList(
        value['fontFamilyFallback'],
        (value) => value,
      ),
      fontSize: JsonClass.maybeParseDouble(value['fontSize']),
      fontStyle: decodeFontStyle(
        value['fontStyle'],
        validate: false,
      ),
      fontWeight: decodeFontWeight(
        value['fontWeight'],
        validate: false,
      ),
      forceStrutHeight: JsonClass.maybeParseBool(value['forceStrutHeight']),
      height: JsonClass.maybeParseDouble(value['height']),
      leading: JsonClass.maybeParseDouble(value['leading']),
      leadingDistribution: decodeTextLeadingDistribution(
        value['leadingDistribution'],
        validate: false,
      ),
      package: value['package'],
    );
  }

  return result;
