This is the error message when using this package.
The current Dart SDK version is 2.1.0-dev.8.0.flutter-bf26f760b1.
The current Flutter SDK version is 0.10.2.
Because every version of flutter_test from sdk depends on http 0.12.0 and app_review >=0.0.5 depends on http ^0.11.3+16, flutter_test from sdk is incompatible with app_review >=0.0.5.
Because app_review <0.0.3 requires SDK version >=1.19.0 <2.0.0 and app_review >=0.0.3 <0.0.5 requires Flutter SDK version ^0.4.0 or ^0.5.2, app_review <0.0.5 is forbidden.
Thus, flutter_test from sdk is incompatible with app_review.
