AnimatedSlide class Null safety
Widget which automatically transitions the child's offset relative to its normal position whenever the given offset changes.
The translation is expressed as an Offset scaled to the child's size. For
example, an Offset with a dx
of 0.25 will result in a horizontal
translation of one quarter the width of the child.
This code defines a widget that uses AnimatedSlide to translate a FlutterLogo
up or down by the amount of it's height with each press of the corresponding button.
To create a local project with this code sample, run:
flutter create --sample=widgets.AnimatedSlide.1 mysample
flutter create --sample=widgets.AnimatedSlide.1 mysample
