Properties
- child → Widget
-
The widget below this widget in the tree.
finalinherited
- curve → Curve
-
The curve of the animation.
final
- curvedValue → double
-
The animation value. It's value is between 0 and 1, interpolated by the
Curve provided.
final
- duration → Duration
-

no setterinherited
- isTransition → bool
-
Whether the animation is in scroll transition or not. Animations behave
differently in scroll transition. This flag is used to determine the
behavior of the animation.
final
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- lerpValues → bool
-
Whether the animation should be lerped or not. If set to false, the
animation value is used as is. If set to true, the animation value is
interpolated between 0 and 1.
final
- linearValue → double
-
The linear animation value. It's value is between 0 and 1.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
