fromDynamic static method

JsonTooltipBuilder? 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:

{
  "decoration": "<BoxDecoration>",
  "enableFeedback": "<bool>",
  "excludeFromSemantics": "<bool>",
  "height": "<double>",
  "margin": "<EdgeInsetsGeometry>",
  "message": "<String>",
  "onTriggered": "<TooltipTriggeredCallback>",
  "padding": "<EdgeInsetsGeometry>",
  "preferBelow": "<bool>",
  "richMessage": "<InlineSpan>",
  "showDuration": "<Duration>",
  "textAlign": "<TextAlign>",
  "textStyle": "<TextStyle>",
  "triggerMode": "<bool>",
  "verticalOffset": "<double>",
  "waitDuration": "<Duration>"
}
