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>",
  "customSemanticsActions": "<Map<CustomSemanticsAction, VoidCallback>>",
  "button": "<bool>",
  "checked": "<bool>",
