FlutterEffectImpl class

Implementation of FlutterEffect that schedules execution at the end of the current Flutter frame.

This effect batches multiple triggers within the same frame and executes only once at the end of the frame, avoiding unnecessary repeated executions during frame rendering.

Example:

final count = Signal(0);

// Effect runs once at end of frame, even if count changes multiple times
final effect = FlutterEffect(() {
  print('Count is: ${count.value}');
});

count.value = 1;
count.value = 2;
count.value = 3;
// Effect executes once at end of frame with count.value = 3
