Answer 1

I've had similar problems. My problem like this:

Because every version of flutter_test from sdk depends on http 0.12.0 and flutter_cache_manager 0.1.2 depends on http ^0.11.3+14, flutter_test from sdk is incompatible with flutter_cache_manager 0.1.2. And because no versions of flutter_cache_manager match >0.1.2 <0.2.0, flutter_test from sdk is incompatible with flutter_cache_manager ^0.1.2.

Here's how I solved it:

dependencies:
    ...
dependency_overrides:
  http: ^0.12.0

so, I thank you can try it:

dependencies:
    ...
dependency_overrides:
  path: ^1.6.0

I assume you are using the beta channel.
I think this doesn't happen in dev channel.

To switch to the dev channel run in a command line shell

flutter channel dev 
flutter doctor 

and try again.
