Looks like a cool addition. We could do a lot more with this I think. A few ideas:

1. Flag Observers that don't have an observable in the builder?
2. Add reaction in the initState of a StatefulWidget with proper dispose
3. Generate stubs for wrapping an observable mutation to happen inside a runInAction()

Already exists in flutter_mobx VsCode extension. But! it fails on some very large pieces of code: https://github.com/Flutterando/flutter_mobx_extension/issues/17

Hi @amondnet, can we move this package under the mobx publisher ?
