I get this error after upgrading flutter to latest version 1.12.13+hotfix.5

Flutter 1.12.13+hotfix.5 • channel stable

Because every version of flutter_test from sdk depends on image 2.1.4 and flutter_luban 0.1.9+2 depends on image ^2.1.9, flutter_test from sdk is incompatible with flutter_luban 0.1.9+2.

The simplest solution is to remove flutter_test

That’s no solution some of us including myself use flutter test to perform unit testing etc on CI pipelines

@soile1991 It's a flutter_test issue. Also, without flutter_test, I think you can do a unit test with the test in flutter_luban

修改flutter下 flutter_test 依赖版本就行了啊

[zhongxinqiang]

直接注释掉pubspec.yaml文件中dev_dependencies下面的flutter_test就可以了：

dev_dependencies:
#  flutter_test:
#    sdk: flutter
