• center
• fill
• start
• startOffset

Implementation

static TabAlignment? decodeTabAlignment(
  dynamic value, {
  bool validate = true,
}) {
  TabAlignment? result;
  if (value is TabAlignment) {
    result = value;
  } else {
    _checkSupported(
      'TabAlignment',
      [
        'center',
        'fill',
        'start',
        'startOffset',
      ],
      value,
    );

    if (value != null) {
      assert(SchemaValidator.validate(
        schemaId: '$_baseSchemaUrl/tab_alignment',
        value: value,
        validate: validate,
      ));
      switch (value) {
        case 'center':
          result = TabAlignment.center;
          break;

        case 'fill':
          result = TabAlignment.fill;
          break;

        case 'start':
          result = TabAlignment.start;
          break;

        case 'startOffset':
          result = TabAlignment.startOffset;
          break;
      }
    }
  }

  return result;
