AnchoredMomentum class final
How a gesture's zoom, bearing, or pitch keeps changing after release.
See mln_anchored_momentum in the
C API reference.
Constructors
- AnchoredMomentum({double? velocity, ScreenPoint? anchor, MomentumDecay decay = const MomentumDecay(), MomentumSnap? snap})

const
Properties
- anchor → ScreenPoint?
-
The screen point that the change keeps in place. Without one, the change
keeps the center of the view in place.
final
- decay → MomentumDecay
-
final
- hashCode → int
-
The hash code for this object.

- runtimeType → Type
-
A representation of the runtime type of the object.

- snap → MomentumSnap?
-
Where the part settles. Without this, it stays where the gesture and its
glide leave it.
final
- velocity → double?
-
How fast the value changed at release: zoom levels per second for zoom,
and degrees per second for bearing and pitch. The part moves only when
this is set.
