fromDynamic static method

JsonSizedBoxBuilder? fromDynamic(
  1. dynamic map, {
  2. JsonWidgetRegistry? registry,
})

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

{
  "height": <double>,
  "width": <double>
}

Implementation

static JsonSizedBoxBuilder? fromDynamic(
  dynamic map, {
  JsonWidgetRegistry? registry,
}) {
  JsonSizedBoxBuilder? result;
  if (map != null) {
    result = JsonSizedBoxBuilder(
      height: JsonClass.parseDouble(map['height']),
      width: JsonClass.parseDouble(map['width']),
    );
  }

  return result;
}
