BouncingScrollSimulation class

An implementation of scroll physics that matches iOS.

Constructors

BouncingScrollSimulation({@required double position, @required double velocity, @required double leadingExtent, @required double trailingExtent, @required SpringDescription spring, Tolerance tolerance: Tolerance.defaultTolerance }): Creates a simulation group for scrolling on iOS, with the given parameters. [...]

leadingExtent → double: When x falls below this value the simulation switches from an internal friction model to a spring model which causes x to "spring" back to leadingExtent.
final
spring → SpringDescription: The spring used used to return x to either leadingExtent or trailingExtent.
final
trailingExtent → double: When x exceeds this value the simulation switches from an internal friction model to a spring model which causes x to "spring" back to trailingExtent.
final
hashCode → int: The hash code for this object. [...]
read-only, inherited
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited
tolerance ↔ Tolerance: How close to the actual end of the simulation a value at a particular time must be before isDone considers the simulation to be "done". [...]
read / write, inherited

dx(double time) → double: The velocity of the object in the simulation at the given time.
override
isDone(double time) → bool: Whether the simulation is "done" at the given time.
override
toString() → String: Returns a string representation of this object.
override
x(double time) → double: The position of the object in the simulation at the given time.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]
inherited

maxSpringTransferVelocity → const double: The maximum velocity that can be transferred from the inertia of a ballistic scroll into overscroll.
