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>,
  "overlayColor": <MaterialStatePropertyColor>,
  "radius": <double>,
  "splashColor": <Color>,
  "splashFactory": <InteractiveInkFeatureFactory>
}

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.
