build method
Subclasses should override this function to actually call the appropriate
build
function (e.g., StatelessWidget.build or State.build) for
their widget.
Implementation
@override
Widget build() {
var fRWidget = widget as FRBaseStatelessWidget;
var buildPoint = BuildTimePoint(
fRWidget._name, fRWidget.runtimeType.toString(), fRWidget._context);
buildPoint.start();
var result = super.build();
buildPoint.end();
return result;
}
