fromDynamic static method

JsonMaterialBuilder? 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:

{
  "animationDuration": <int; millis>,
  "borderOnForeground": <bool>,
  "borderRadius": <BorderRadius>,
  "clipBehavior": <Clip>,
  "color": <Color>,
  "elevation": <double>,
  "margin": <EdgeInsetsGeometry>,
  "materialType": <MaterialType>,
  "padding": <EdgeInsetsGeometry>,
  "shadowColor": <Color>,
  "surfaceTintColor": <Color>,
  "shape": <ShapeBorder>,
  "textStyle": <TextStyle>
}
