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>"
}
