firebase_analytics_web should be updated to work with firebase 8.0.0

[eggnstone]

firebase is currently at version 8.0.0 which does not work with firebase_analytics_web 0.1.1.
Please update firebase_analytics_web and firebase_analytics.

Because firebase_analytics_web 0.1.1 depends on firebase ^7.3.0 and no versions of firebase_analytics_web match >0.1.1 <0.2.0, firebase_analytics_web ^0.1.1 requires firebase ^7.3.0.

So, because xyz depends on both firebase ^8.0.0 and firebase_analytics_web ^0.1.1, version solving failed.

Or should this have better been a bug report?
