fromDynamic static method

JsonCupertinoSwitchBuilder? 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:

{
  "activeColor": "<Color>",
  "autovalidatMode": "<AutovalidateMode>",
  "dragStartBehavior": "<DragStartBehavior>",
  "enabled": "<bool>",
  "label": "<String>",
  "onChanged": "<ValueCallback<bool>>",
  "onSaved": "<ValueCallback<bool>>",
  "restorationId": "<String>",
  "thumbColor": "<Color>",
  "trackColor": "<Color>",
  "validators": "<List<ValueValidator>>",
  "value": "<bool>",
  "visualDensity": "<VisualDensity>"
}

As a note, the ValueCallback<bool> cannot be decoded via JSON. Instead, the only way to bind those values to the builder is to use a function or a variable reference via the JsonWidgetRegistry.

Implementation

static JsonCupertinoSwitchBuilder? fromDynamic(
  dynamic map, {
  JsonWidgetRegistry? registry,

  JsonCupertinoSwitchBuilder? result;

  if (map != null) {
    result = JsonCupertinoSwitchBuilder(
      activeColor: ThemeDecoder.decodeColor(
        map['activeColor'],
        validate: false,
      ),
      autovalidateMode: map['autovalidate'] == null
          ? ThemeDecoder.decodeAutovalidateMode(
              map['autovalidateMode'],
              validate: false,
            )
          : JsonClass.parseBool(map['autovalidate']) == true
              ? AutovalidateMode.always
              : AutovalidateMode.disabled,
      dragStartBehavior: ThemeDecoder.decodeDragStartBehavior(

        validate: false,
