React Native (Web) and Emotion 11 should use StyleSheet.create ?

[efoken]

The problem

I think Emotion should use StyleSheet.create instead of StyleSheet.flatten, even if this maybe affects performance (?) it is in my opinion the best solution, because StyleSheet.flatten only creates "inline styles" and StyleSheet.create create an instance which is referenced later.

And besides that, when someones uses React Native Web it is always better to use StyleSheet.create, because it creates atomic CSS classes while StyleSheet.flatten only creates inline styles...

Proposed solution

Switch to StyleSheet.create in primitives-core package.

I've checked what Styled Components do and they indeed use StyleSheet.create: https://github.com/styled-components/styled-components/blob/28b4c28f1ebd1ea5a34717df2fe49634461285b1/packages/styled-components/src/models/InlineStyle.js#L28
