ConnectionEffect class abstract interface

Abstract interface for connection animation effects.

Custom animation effects can be created by implementing this interface. Each effect encapsulates its own configuration and rendering logic.

Example:

class MyCustomEffect implements ConnectionEffect {
  MyCustomEffect({required this.customParam});

  final double customParam;

  @override
  void paint(Canvas canvas, Path path, Paint basePaint, double animationValue) {
    // Custom animation rendering logic
  }
}
