fromDynamic static method
Builds the builder from a Map-like dynamic structure. This expects the JSON format to be of the following structure:
{
"clipBehavior": <Clip>,
"controller": <ScrollController>,
"dragStartBehavior": <DragStartBehavior>,
"keyboardDismissBehavior": <ScrollViewKeyboardDismissBehavior>,
"padding": <EdgeInsetsGeometry>,
"physics": <ScrollPhysics>,
"primary": <bool>,
"restorationId": <String>,
"reverse": <bool>,,
"scrollDirection": <Axis>
}
As a note, the ScrollController 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.
