Flutter has powerful, flexible animation support — from simple implicit animations to fully-controlled explicit animations. Animations enhance UX with smooth transitions and motion, and Flutter's widget-based system makes them approachable.
Implicit animations (the easy way)
// implicitly-animated widgets animate AUTOMATICALLY when their properties change
AnimatedContainer(
duration: Duration(milliseconds: 300),
width: _expanded ? 200 : 100, // change width → it animates smoothly
height: _expanded ? 200 : 100,
color: _expanded ? Colors.blue : Colors.red,
)
// just change the value (with setState) → Flutter animates the transition
// others: AnimatedOpacity, AnimatedPadding, AnimatedPositioned, etc.
Implicit animations (, , etc.) animate automatically when their properties change — the easiest way to add animation.
