fromDynamic static method

JsonPlaceholderBuilder? 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:

{
  "color": "<Color>",
  "fallbackHeight": "<double>",
  "fallbackWidth": "<double>",
  "strokeWidth": "<double>"
}

Implementation

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

  if (map != null) {
    result = JsonPlaceholderBuilder(
      color: ThemeDecoder.decodeColor(
            map['color'],
            validate: false,
          ) ??
          const Color(0xFF455A64),
      fallbackHeight: JsonClass.maybeParseDouble(
        map['fallbackHeight'],
        400.0,
      )!,
      fallbackWidth: JsonClass.maybeParseDouble(
        map['fallbackWidth'],
        400.0,
      )!,
      strokeWidth: JsonClass.maybeParseDouble(
        map['strokeWidth'],
        2.0,
      )!,
    );
  }

  return result;
