toJson method

@override Map<String, dynamic> toJson()

Abstract function that concrete classes must implement. This must encode the internal data model to a JSON compatible representation.

While not required, it is suggested to call removeNull before returning.

Implementation

@override
Map<String, dynamic> toJson() {
  return JsonClass.removeNull({
    'alignment': ThemeEncoder.encodeAlignment(
      alignment,
    ),
    'boundaryMargin': EdgeInsets.zero == boundaryMargin
        ? null
        : ThemeEncoder.encodeEdgeInsets(
            boundaryMargin,
          ),
    'clipBehavior': Clip.hardEdge == clipBehavior
        ? null
        : ThemeEncoder.encodeClip(
            clipBehavior,
          ),
    'constrained': true == constrained ? null : constrained,
    'interactionEndFrictionCoefficient':
        0.0000135 == interactionEndFrictionCoefficient
            ? null
            : interactionEndFrictionCoefficient,
    'maxScale': 2.5 == maxScale ? null : maxScale,
    'minScale': 0.8 == minScale ? null : minScale,
    'onInteractionEnd': onInteractionEnd,
    'onInteractionStart': onInteractionStart,
    'onInteractionUpdate': onInteractionUpdate,
    'panAxis': PanAxis.free == panAxis
        ? null
        : ThemeEncoder.encodePanAxis(
            panAxis,
          ),
    'panEnabled': true == panEnabled ? null : panEnabled,
    'scaleEnabled': true == scaleEnabled ? null : scaleEnabled,
    'scaleFactor':
        kDefaultMouseScrollToScaleFactor == scaleFactor ? null : scaleFactor,
    'trackpadScrollCausesScale':

    'transformationController': transformationController,
