fromDynamic static method

JsonCupertinoSwitchBuilder? 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:

{
  "activeColor": <Color>,
  "autovalidatMode": <AutovalidateMode>,
  "dragStartBehavior": <DragStartBehavior>,
  "enabled": <bool>,
  "label": <String>,
  "onChanged": <ValueCallback<bool>>,
  "onSaved": <ValueCallback<bool>>,
  "thumbColor": <Color>,
  "trackColor": <Color>,
  "validators": <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

  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'])
          : JsonClass.parseBool(map['autovalidate']) == true
              ? AutovalidateMode.always
              : AutovalidateMode.disabled,
      dragStartBehavior: ThemeDecoder.decodeDragStartBehavior(
        map['dragStartBehavior'],
        validate: false,
      ),
      enabled:
          map['enabled'] == null ? true : JsonClass.parseBool(map['enabled']),

          ? null
