const constructors in Flutter

Why does Flutter recommend const constructors such as const Text('Hello') wherever possible?

A.const widgets are created once and reused, so Flutter can skip rebuilding them when the parent rebuildsB.const widgets are drawn only by the GPUC.const tells Flutter to paint the widget once into a cached bitmap and reuse that image on every later frame, even if its text changesD.Without const, a widget cannot be stateless
