Description

When using alchemist in an app that does not specify uses-material-design: true (either by removing it, or by explicitly setting it to false), the following error is displayed:

package:alchemist has `uses-material-design: true` set but the primary pubspec contains `uses-material-design: false`. If the application needs material icons, then `uses-material-design`  must be set to true.

Steps to reproduce

1. Create a blank app and remove the line uses-material-design: true from the pubspec.
2. Import alchemist.
3. Run the app.

Expected behavior

This error should not appear.
