Packages that rely on image 3.x will have compatibility issues with CamerAwesome.
However, since we have compatibility issues because other packages already rely on image 4.x, it's worth the upgrade.

Note: this PR can't be merged since it depends on a git dependency for photofilters.
Photofilters will have to be upgraded first.

Are you sure this is enough?
I'm having all sort of issues when trying to override the dependencies with the ones you suggested and image package 4.0.x

camerawesome-1.2.1/lib/src/orchestrator/states/photo_camera_state.dart:153:44: Error: Too many positional arguments: 0 allowed, but 3 found.
image-4.0.13/lib/src/image/image.dart:198:3: Context: Found this candidate, but the arguments don't match.
camerawesome-1.2.1/lib/src/orchestrator/states/photo_camera_state.dart:159:56: Error: The argument type 'Image' can't be assigned to the parameter type 'String'.
camerawesome-1.2.1/lib/src/orchestrator/states/photo_camera_state.dart:159:67: Error: The argument type 'String' can't be assigned to the parameter type 'Image'.

Yes, my bad.
I've discussed that with the team and we are using a package to create the filters.
It's currently using version 3.x of images and the author is not answering to our PR.
We are working to remove this dependency.

FYI I think it is working. i haven't tested filters, but the rest is compiling and looks like working fine.
