clone the old flutter project and it is not working, any thoughts how to fix this - flutter

Question

I have cloned this project https://github.com/2d-inc/developer_quest
and when I try to run the project on android then get the following error
The current Dart SDK version is 2.15.0-42.0.dev.
Because test >=1.16.0-nullsafety <1.16.0-nullsafety.8 requires SDK version >=2.10.0-0 <2.12.0 and test >=1.16.0-nullsafety.8 <1.16.0-nullsafety.18 depends on typed_data >=1.3.0-nullsafety <1.3.0, test >=1.16.0-nullsafety <1.16.0-nullsafety.18 requires typed_data >=1.3.0-nullsafety <1.3.0.
And because test >=1.16.0-nullsafety.18 <1.16.0-nullsafety.19 depends on test_api 0.2.19-nullsafety.7 and test >=1.3.0 <1.12.0 depends on boolean_selector ^1.0.0, test >=1.3.0 <1.12.0-∞ or >=1.16.0-nullsafety <1.16.0-nullsafety.19 requires typed_data >=1.3.0-nullsafety <1.3.0 or test_api 0.2.19-nullsafety.7 or boolean_selector ^1.0.0.
And because test >=1.12.0 <1.13.0 depends on test_api 0.2.14 and test >=1.13.0 <1.14.5 depends on test_api 0.2.15, test >=1.3.0 <1.14.5-∞ or >=1.16.0-nullsafety <1.16.0-nullsafety.19 requires typed_data >=1.3.0-nullsafety <1.3.0 or test_api 0.2.14 or 0.2.15 or 0.2.19-nullsafety.7 or boolean_selector ^1.0.0.
And because test >=1.14.5 <1.15.0 depends on test_api 0.2.16 and test >=1.15.0 <1.15.3 depends on test_api 0.2.17, test >=1.3.0 <1.15.3-∞ or >=1.16.0-nullsafety <1.16.0-nullsafety.19 requires typed_data >=1.3.0-nullsafety <1.3.0 or test_api 0.2.14 or 0.2.15 or 0.2.16 or 0.2.17 or 0.2.19-nullsafety.7 or boolean_selector ^1.0.0.
And because test >=1.15.3 <1.15.5 depends on test_api 0.2.18 and test >=1.15.5 <1.16.0-nullsafety depends on test_api 0.2.18+1, test >=1.3.0 <1.16.0-nullsafety.19 requires typed_data >=1.3.0-nullsafety <1.3.0 or test_api 0.2.14 or 0.2.15 or 0.2.16 or 0.2.17 or 0.2.18 or 0.2.18+1 or 0.2.19-nullsafety.7 or boolean_selector ^1.0.0.
And because test >=1.16.0-nullsafety.19 <1.16.6 depends on test_api 0.2.19 and every version of flutter_driver from sdk depends on boolean_selector 2.1.0, if test >=1.3.0 <1.16.6 and flutter_driver any from sdk then test_api 0.2.14 or 0.2.15 or 0.2.16 or 0.2.17 or 0.2.18 or 0.2.18+1 or 0.2.19-nullsafety.7 or 0.2.19 or typed_data >=1.3.0-nullsafety <1.3.0.
And because every version of flutter_driver from sdk depends on test_api 0.4.3 and every version of flutter_test from sdk depends on typed_data 1.3.0, one of flutter_test any from sdk or test >=1.3.0 <1.16.6 or flutter_driver any from sdk must be false.
And because test >=1.16.6 depends on webkit_inspection_protocol ^1.0.0 which depends on logging ^1.0.0, if flutter_test any from sdk and flutter_driver any from sdk and test >=1.3.0 then logging ^1.0.0.
And because dev_rpg depends on both flutter_test any from sdk and flutter_driver any from sdk, test >=1.3.0 requires logging ^1.0.0.
So, because dev_rpg depends on both logging ^0.11.3+2 and test ^1.6.1, version solving failed.

I have tried upgrading
flutter channel dev
flutter create . ```

Well as the errors say, the project has some dependencies that are not met by the version of flutter you have (because of the libraries that are shipped with flutter itself).
The pubspec.yaml of the project says it is supposed to work with flutter version 1.5.4. so, If you want to run that project you would need to download that compatible flutter sdk
