Setting custom parameters to screen_view events with React Native

[Alon Haber]

Following this blog post Iv'e tried to log the automatic screen_view event with custom parameters (in addition to screen_name / screen_class). When I tried doing this in a native app environment - it worked. However, my app is based on React native and I use the package of React Native Firebase. When i tried to implement it in this environment it didn't work at all. Is it possible to add custom parameters with React Native Firebase?

Thanks!
