Animates the position of a widget relative to its normal position.
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.
By default, the offsets are applied in the coordinate system of the canvas (so positive x offsets move the child towards the right). If a textDirection is provided, then the offsets are applied in the reading direction, so in right-to-left text, positive x offsets move towards the left, and in left-to-right text, positive x offsets move towards the right.
Here's an illustration of the SlideTransition widget, with its position animated by a CurvedAnimation set to Curves.elasticIn:
The following code implements the SlideTransition as seen in the video above:
To create a local project with this code sample, run:
flutter create --sample=widgets.SlideTransition.1 mysample
