AnimatedPadding constructor Null safety

AnimatedPadding(
  1. {Key? key,
  2. required EdgeInsetsGeometry padding,
  3. Widget? child,
  4. Curve curve = Curves.linear,
  5. required Duration duration,
  6. VoidCallback? onEnd}
)

Creates a widget that insets its child by a value that animates implicitly.

The padding, curve, and duration arguments must not be null.

Implementation

AnimatedPadding({
  super.key,
  required this.padding,
  this.child,
  super.curve,
  required super.duration,
  super.onEnd,
}) : assert(padding != null),
     assert(padding.isNonNegative);
