fromDynamic static method

JsonFloatingActionButtonBuilder? 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:

{
  "autofocus": "<bool>",
  "backgroundColor": "<Color>",
  "clipBehavior": "<Clip>",
  "disabledElevation": "<double>",
  "elevation": "<double>",
  "enableFeedback": "<bool>",
  "focusColor": "<Color>",
  "focusElevation": "<double>",
  "focusNode": "<FocusNode>",
  "foregroundColor": "<Color>",
  "heroTag": "<Object>",
  "highlightElevation": "<double>",
  "hoverColor": "<Color>",
  "hoverElevation": "<double>",
  "isExtended": "<bool>",
  "materialTapTargetSize": "<MaterialTapTargetSize>",
  "mini": "<bool>",
  "mouseCursor": "<MouseCursor>",
  "onPressed": "<VoidCallback>",
  "shape": "<ShapeBorder>",
  "splashColor": "<Color>",
  "tooltip": "<String>"
}

As a note, the FocusNode, Object, and VoidCallback cannot be decoded via JSON. Instead, the only way to bind those values to the builder is to use a function or a variable reference via the JsonWidgetRegistry.
