MotionInterval class abstract
The abstract class for an motion that changes properties over a time interval, optionally using an easing curve.

- Implementers
Constructors
- MotionInterval([double _duration = 0.0, Curve? curve])
- Creates a new MotionInterval, typically you will want to pass in a duration to specify how long time the motion will take to complete.
Properties
- curve ↔ Curve?
-
The animation curve used to ease the animation.
getter/setter pair
- duration → double
-
The total time it will take to complete the motion, in seconds.
no setteroverride
- hashCode → int
-
The hash code for this object.
no setterinherited
- isFinished → bool
-
Returns true if the Motion has completed.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
step(
double dt) → void -
Moves to the next time step in an motion,
dt
is the delta time since the last time step in seconds. Typically this method is called from the MotionController.override -
toString(
) → String -
A string representation of this object.
inherited
-
update(
double t) → void -
Sets the motion to a specific point in time. The
t
value that is passed in is a normalized value 0.0 to 1.0 of the duration of the motion. Every motion will always recieve a callback with the end time point (1.0), unless it is cancelled.inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
