Issue with Giphy

[rlee1990]

I receive an error with the latest version of flutter.

Because every version of flutter_test from sdk depends on http 0.12.0 and giphy_client 0.0.1 depends on http ^0.11.3+16, flutter_test from sdk is incompatible with giphy_client 0.0.1. And because no versions of giphy_client match >0.0.1 <0.1.0, flutter_test from sdk is incompatible with giphy_client ^0.0.1. So, because flutter_crushn depends on both giphy_client ^0.0.1 and flutter_test any from sdk, version solving failed.
