fromDynamic static method

JsonTextBuilder? 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:

{
  "locale": <Locale>,
  "maxLines": <int>,
  "overflow": <TextOverflow>,
  "semanticsLabel": <String>,
  "softWrap": <bool>,
  "strutStyle": <StrutStyle>,
  "style": <TextStyle>,
  "text": <String>,
  "textAlign": <TextAlign>,
  "textDirection": <TextDirection>,
  "textHeightBehavior": <TextHeightBehavior>,
  "textScaleFactor": <double>,
  "textWidthBasis": <TextWidthBasis>,
}
