How to listen events from dart/flutter?

[normancarcamo]

Hi there, I would like to know if there is any guide to follow about events but from flutter?

I want to dispatch an event every time an animation that is running repeatedly starts again.
Using the advance method from the controller doesn't help me too much because the animation is always running indefinitely, so I am thinking on making use of them to see if I can replace the animation on a specific time.
