An in-range update of material-ui is breaking the build 🚨

[greenkeeper[bot]]

There have been updates to the material-ui monorepo:

• • The dependency @material-ui/core was updated from 3.6.2 to 3.7.0.

🚨 View failing branch.

This version is covered by your current version range and after updating it in your project the build failed.

This monorepo update includes releases of one or more dependencies which all belong to the material-ui group definition.

material-ui is a direct dependency of this project, and it is very likely causing it to break. If other packages depend on yours, this update is probably also breaking those in turn.
