fromDynamic static method

JsonSemanticsBuilder? 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:

{
  "attributedDecreasedValue": <AttributedString>,
  "attributedHint": <AttributedString>,
  "attributedIncreasedValue": <AttributedString>,
  "attributedLabel": <AttributedString>,
  "attributedValue": <AttributedString>,
