fromDynamic static method

JsonListTileBuilder? 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:

{
  "autofocus": <bool>,
  "contentPadding": <EdgeInsetsGeometry>,
  "dense": <bool>,
  "enableFeedback": <bool>,
  "enabled": <bool>,
  "focusNode": <Color>,
  "focusNode": <FocusNode>,
  "horizontalTitleGap": <double>,
  "hoverColor": <Color>,
  "iconColor": <Color>,
  "isThreeLine": <bool>,
  "leading": <JsonWidgetData>,
  "minLeadingWidth": <double>,
  "minVerticalPadding": <double>,
  "mouseCursor": <MouseCursor>,
  "onLongPress": <VoidCallback>,
  "onTap": <VoidCallback>,
  "selectedColor": <Color>,
  "selected": <bool>,
  "shape": <ShapeBorder>,
  "selectedTileColor": <Color>,
  "style": <ListTileStyle>,
  "subtitle": <JsonWidgetData>,
  "textColor": <Color>,
  "tileColor": <Color>,
  "title": <JsonWidgetData>,
  "trailing": <JsonWidgetData>,
  "visualDensity": <VisualDensity>
}

As a note, the VoidCallback and FocusNode objects 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.
