fromDynamic static method

JsonCheckboxBuilder? 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>,
  "autofocus": <bool>,
  "autovalidateMode": <AutovalidateMode>,
  "checkColor": <Color>,
  "enabled": <bool>,
  "fillColor": <MaterialStateProperty<Color>>,
  "focusColor": <Color>,
  "focusNode": <FocusNode>,
  "hoverColor": <Color>,
  "label": <String>,
  "materialTapTargetSize": <MaterialTapTargetSize>,
  "mouseCursor": <MouseCursor>,
  "onChanged": <ValueChanged<bool>>,
  "onSaved": <ValueChanged<onSaved>>,
  "overlayColor": <MaterialStateProperty<Color>>,
  "shape": <OutlinedBorder>,
  "side": <BorderSide>,
  "splashRadius": <double>,
  "tristate": <bool>,
  "validators": <ValueValidator[]>,
  "value": <bool>,
  "visualDensity": <VisualDensity>,
}

As a note, the FocusNode and ValueChanged<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.
