migrate mobx to peer and dev dependencies

[heralight]

To avoid mobx update dependency everytime and to not force projects to upgrade with RNRF...

A far more better option is to change these dependencies to peer dependencies ...
Mobx Issue and related docs:
mobxjs/mobx#1082

Mobx docs:

If there should be only one mobx instance (libraries should cooperate & react to each other)
Use peer dependencies

Does it require different setup process for end user who doesn't use mobx?

[heralight]

Sorry, I missed your question...

In recent versions peer dependencies will not be installed automatically, but user will be pointed out that he should install them. So he has to install yarn mobx mobx-react. But it is the only correct thing to do, otherwise he cannot (properly) update mobx versions etc without you releasing a different version from rnrf.

What about following idea - clone this repo and use react-native-router-mobx with peer mobx dependencies (who are using mobx in their projects) and use normal dependencies for this project (for everybody who don't use mobx) ?

[heralight]

I already done this (my fork, my push, as you can see in this push request, I use it directly in my projects). but how it's done actually in react-native-router-mobx with normal mobx dependencies, it's clearly not the right direction. and I don't understand the limitation for everybody who don't use mobx, it's one line to set up to have flexibility and no more mobx maintenance...

Ok, let's try your way, could you update README ?
