//In the declarative style, view configurations (such as Flutter’s Widgets) | |
//are immutable and are only lightweight “blueprints”. | |
//To change the UI, a Widget triggers a rebuild on itself | |
//(most commonly by calling setState() on StatefulWidgets | |
//in Flutter) and constructs a new Widget subtree. | |
