Breaking changes

Version 1.0.0

/!\ Warning /!\ The lib has been upgraded to match with new React and React Native standards (hooks, deprecated methods, etc...). The version 1.0.0 may contain some bugs or regressions. Ping me in issues if you notice a bad behaviour of the upgraded lib on your project. I advice you to update the lib in a separate commit to roll back if necessary. However the lib should work for most of cases, so don't be scared to update the lib. It is a first step to improve the lib in the future, so please be understanding 😇
