MultiWidget class

Builds multiple nested widgets.

Designed for cases when there's many nested but relatively simple widgets. This allows to increase readability by flattening code structure. Also, by using the MultiWidget.keyed constructor, allows to conditionally nest widgets without losing their state:

MultiWidget.keyed([
  MapEntry("a", (child) => A(child: child),
  if(condition) MapEntry("b", (child) => B(child: child),
  MapEntry("c", (child) => C(child: child),
]);
