fromDynamic static method

JsonRowBuilder? fromDynamic(dynamic map, { JsonWidgetRegistry? registry, })

Builds the builder from a Map-like dynamic structure. This expects the JSON format to be of the following structure:

{
  "crossAxisAlignment": "<CrossAxisAlignment>",
  "mainAxisAlignment": "<MainAxisAlignment>",
  "mainAxisSize": "<MainAxisSize>",
  "textBaseline": "<TextBaseline>",
  "textDirection": "<TextDirection>",
  "verticalDirection": "<VerticalDirection>"
}

Implementation

static JsonRowBuilder? fromDynamic(
  dynamic map, {
  JsonWidgetRegistry? registry,
}) {
  JsonRowBuilder? result;

  if (map != null) {
    result = JsonRowBuilder(
      crossAxisAlignment: ThemeDecoder.decodeCrossAxisAlignment(
            map['crossAxisAlignment'],
            validate: false,
          ) ??
          CrossAxisAlignment.center,
      mainAxisAlignment: ThemeDecoder.decodeMainAxisAlignment(
            map['mainAxisAlignment'],
            validate: false,
          ) ??
          MainAxisAlignment.start,
      mainAxisSize: ThemeDecoder.decodeMainAxisSize(
            map['mainAxisSize'],
            validate: false,
          ) ??
          MainAxisSize.max,
      textBaseline: ThemeDecoder.decodeTextBaseline(
        map['textBaseline'],
        validate: false,
      ),
      textDirection: ThemeDecoder.decodeTextDirection(
        map['textDirection'],
        validate: false,
      ),
      verticalDirection: ThemeDecoder.decodeVerticalDirection(
            map['verticalDirection'],
            validate: false,
          ) ??
          VerticalDirection.down,
    );
  }

  return result;
