fromDynamic static method

JsonAppBarBuilder? 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:

{
  "actions": <JsonWidgetData[]>,
  "actionsIconTheme": <IconThemeData>,
  "automaticallyImplyLeading": <bool>,
  "backgroundColor": <Color>,
  "bottom": <JsonWidgetData>,
  "bottomOpacity": <double>,
  "centerTitle": <bool>,
  "elevation": <double>,
  "excludeHeaderSemantics": <bool>,
  "flexibleSpace": <JsonWidgetData>,
  "foregroundColor": <Color>,
  "iconTheme": <IconThemeData>,
  "leading": <bool>,
  "leadingWidth": <double>,
  "primary": <bool>,
  "shadowColor": <Color>,
  "shape": <ShapeBorder>,
  "systemOverlayStyle": <SystemUiOverlayStyle>,
  "titleTextStyle": <TextStyle>,
  "toolbarTextStyle": <TextStyle>,
  "title": <JsonWidgetData>,
  "titleSpacing": <double>,
  "toolbarHeight": <double>,
  "toolbarOpacity": <double>
}
