fromDynamic static method
Builds the builder from a Map-like dynamic structure. This expects the JSON format to be of the following structure:
{
"autofocus": <bool>,
"backgroundColor": <Color>,
"clipBehavior": <Clip>,
"disabledElevation": <double>,
"elevation": <double>,
"enableFeedback": <bool>,
"focusColor": <Color>,
"focusElevation": <double>,
"focusNode": <FocusNode>,
"foregroundColor": <Color>,
"heroTag": <Object>,
"highlightElevation": <double>,
"hoverColor": <Color>,
"hoverElevation": <double>,
"isExtended": <bool>,
"materialTapTargetSize": <MaterialTapTargetSize>,
"mini": <bool>,
"mouseCursor": <MouseCursor>,
"onPressed": <VoidCallback>,
"shape": <ShapeBorder>,
"splashColor": <Color>,
"tooltip": <String>
}
As a note, the FocusNode, Object, and VoidCallback 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.
