goBallistic method
- @override
override
Start a physics-driven simulation that settles the pixels position, starting at a particular velocity.
This method defers to ScrollPhysics.createBallisticSimulation, which typically provides a bounce simulation when the current position is out of bounds and a friction simulation when the position is in bounds but has a non-zero velocity.
The velocity should be in logical pixels per second.
Implementation
@override
void goBallistic(double velocity) {
assert(pixels != null);
final Simulation simulation = physics.createBallisticSimulation(this, velocity);
if (simulation != null) {
beginActivity(BallisticScrollActivity(this, simulation, context.vsync));
} else {
goIdle();
}
}
