AnimatedPadding class Null safety

Animated version of Padding which automatically transitions the indentation over a given duration whenever the given inset changes.

Here's an illustration of what using this widget looks like, using a curve of Curves.fastOutSlowIn.

The following code implements the AnimatedPadding widget, using a curve of Curves.easeInOut.

To create a local project with this code sample, run:
flutter create --sample=widgets.AnimatedPadding.1 mysample

Constructors

AnimatedPadding({Key? key, required EdgeInsetsGeometry padding, Widget? child, Curve curve = Curves.linear, required Duration duration, VoidCallback? onEnd}): Creates a widget that insets its child by a value that animates implicitly.

child → Widget?: The widget below this widget in the tree.
final
curve → Curve: The curve to apply when animating the parameters of this container.
finalinherited
duration → Duration: The duration over which to animate the parameters of this container.
finalinherited
hashCode → int: The hash code for this object.

key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
onEnd → VoidCallback?: Called every time an animation completes.
finalinherited
padding → EdgeInsetsGeometry: The amount of space by which to inset the child.
final
runtimeType → Type: A representation of the runtime type of the object.
