@Khalid-Nowaf - what version of dart are you using?

Khalid-Nowaf commented 4 years ago

@devoncarew I'm using Dart 2.7.0

bwilkerson commented 4 years ago

Does version 0.2.3 work correctly?

I suspect that the package was updated to work with the upcoming version 2.8.0 of the SDK and was then published without correctly updating the SDK constraints to indicate its dependence on a later version of the SDK. I know that 0.3.0 works correctly with the version of ffi on master. But if you could verify for me that 0.2.3 works with Dart 2.7.0, that would help to confirm my suspicion.
