Hi, on_started is meant to be used after `animation` or `anima_XXXX` (property). Also looking at your screenshot Anima is not meant to be used like that, you always need to...

Yes, animating a boolean is not supported. What are you trying to achieve? What kind of animation do you want to create?

So, you can animate the opacity instead. Maybe the built-in "Flash" animation is what are you looking for? ``` Anima.node(self).anima_animation('flash').play() ```

How are you building the app in debug mode? Are you using the `yarn owl build` command or the `react-native run-ios` one?
