fromDynamic static method

JsonInkWellBuilder? 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>",
  "borderRadius": "<BorderRadius>",
  "canRequestFocus": "<bool>",
  "customBorder": "<ShapeBorder>",
  "enableFeedback": "<bool>",
  "excludeFromSemantics": "<bool>",
  "focusColor": "<Color>",
  "focusNode": "<FocusNode>",
  "highlightColor": "<Color>",
  "hoverColor": "<Color>",
  "mouseCursor": "<MouseCursor>",
  "onDoubleTap": "<GestureTapCallback>",
  "onFocusChange": "<ValueChanged<bool>>",
  "onHighlightChanged": "<ValueChanged<bool>>",
  "onHover": "<ValueChanged<bool>>",
  "onLongPress": "<GestureLongPressCallback>",
  "onTap": "<GestureTapCallback>",
  "onTapCancel": "<GestureTapCancelCallback>",
  "onTapDown": "<GestureTapDownCallback>",
  "onTapUp": "<GestureTapUpCallback>",
  "overlayColor": "<MaterialStatePropertyColor>",
  "radius": "<double>",
  "splashColor": "<Color>",
  "splashFactory": "<InteractiveInkFeatureFactory>",
  "statesController": "<MaterialStatesController>"
}

As a note, the FocusNode, GestureTapCallback, GestureLongPressCallback, GestureTapCancelCallback, GestureTapDownCallback, ValueCallback<bool>, 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.
