React-native Could not find generated setter for class

Question

I'm trying to implement ViewGroupManager to create my own native view. For one of my tasks, I need a link to my view instance. To receive it I use @ReactProperty annotation, but it looks like it doesn't work (even for not my components). I found in a log many lines "Could not find generated setter for class..."

Import for ReactProp annotation is:

import com.facebook.react.uimanager.annotations.ReactProp;

Answer 1

I fixed it for my own component by setting the @ReactProp(name="...") correct.

I had made a mistakes here and it did not matched what was declared in javascript. So the warning means: I am missing one of the props I can set!

Check your javascript code and make sure that every prop there has a matching @ReactProp

So for the 6692 bug I suspect the same thing is going on...
