Difference between TickerProviderStateMixin and SingleTickerProviderStateMixin?

Question

When I work with AnimationController it requires a vsync parameter. I have researched, should I use TickerProviderStateMixin or SingleTickerProviderStateMixin, currently I still do not know what is the difference between them. Thanks if you give me an explanation about it.

When you are using single AnimationController use SingleTickerProviderStateMixin.

If you need more than one AnimationController use TickerProviderStateMixin.

We need TickerProviderStateMixin below snippet because we have two AnimationController

class _TrickerExampleState extends State<TrickerExample>
    with TickerProviderStateMixin {
  late AnimationController controller1;
  late Animation<double> fadeAnimation;

  late AnimationController controller2;
  late Animation<Alignment> positionAnimation;
