fromDynamic static method

JsonSetWidgetBuilder? 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:

{
  "<key>": "<JsonWidgetData>"
}

Where the key is any arbitrary String. That key will be used as the key on JsonWidgetRegistry.setValue and the JsonWidgetData value will be used as the value.

Implementation

static JsonSetWidgetBuilder? fromDynamic(
  dynamic map, {
  JsonWidgetRegistry? registry,
}) {
  JsonSetWidgetBuilder? result;
  final innerRegistry = registry ?? JsonWidgetRegistry.instance;

  if (map != null) {
    final widgets = <String, JsonWidgetData?>{};
    map.forEach(
      (key, value) => widgets[key] = JsonWidgetData.fromDynamic(value),
    );

    result = JsonSetWidgetBuilder(widgets: widgets);
    registry ??= JsonWidgetRegistry.instance;
    result.widgets?.forEach(
      (key, value) => innerRegistry.setValue(
        key,
        value,
        originator: null,
      ),
    );
  }

  return result;
