React Native + Firebase: Saving data with id increment

Question

I would like to know if it's possible to save data into firebase and instead to get this kind of number as keys:

Insert this: 0,1,2,3,4 like MySql do.

Is that possible and how can I do this?

Thank you

To my knowledge, Firebase does not support this behavior natively. You can, however, set your elements to whatever ID you like, so you could achieve this yourself.

See this answer and this blog post for further explanation.
