goBallistic method

  1. @override
void goBallistic (
  1. double velocity
)
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();
  }
}
