fromDynamic static method
Builds the builder from a Map-like dynamic structure. This expects the JSON format to be of the following structure:
{
"dragDevices": "<Set<PointerDeviceKind>>",
"overscroll": "<bool>",
"physics": "<ScrollPhysics>",
"platform": "<TargetPlatform>",
"scrollbars": "<bool>""
}
