decodeVisualDensity static method

VisualDensity? decodeVisualDensity(dynamic value, { bool validate = true, })

Decodes the value to a VisualDensity. Supported values are:

• adaptivePlatformDensity
• comfortable
• compact
• standard

Implementation

static VisualDensity? decodeVisualDensity(
  dynamic value, {
  bool validate = true,
}) {
  VisualDensity? result;
  if (value is VisualDensity) {
    result = value;
  } else {
    _checkSupported(
      'VisualDensity',
      [
        'adaptivePlatformDensity',
        'comfortable',
        'compact',
        'standard',
      ],
      value,
    );

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

        case 'comfortable':
          result = VisualDensity.comfortable;
          break;

        case 'compact':
          result = VisualDensity.compact;
          break;

        case 'standard':
          result = VisualDensity.standard;
          break;
      }
    }
  }

  return result;
