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>",
  "selectedTileColor": "<Color>",
  "shape": "<ShapeBorder>",
  "splashColor": "<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.
