fromDynamic static method

JsonOpacityBuilder? 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:

{
  "alwaysIncludeSemantics": <bool>,
  "opacity": <double>
}

Implementation

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

  if (map != null) {
    result = JsonOpacityBuilder(
      alwaysIncludeSemantics:
          JsonClass.parseBool(map['alwaysIncludeSemantics']),
      opacity: JsonClass.parseDouble(map['opacity'], 1.0)!,
    );
  }

  return result;
}
