Flutter image version issue

I have just upgraded my flutter version and now I am facing the following issue when I get the packages in pubsec.yml file:

Because every version of flutter_test from sdk depends on image 2.1.4 and Instant_Feedback depends on image ^2.1.9, flutter_test from sdk is forbidden.

So, because Instant_Feedback depends on flutter_test any from sdk, version solving failed. pub get failed (1; So, because Instant_Feedback depends on flutter_test any from sdk, version solving failed.)

My pubsec.yml file

dependencies:
  flutter:
    sdk: flutter

Because every version of flutter_test from sdk depends on image 2.1.4 and Instant_Feedback depends on image ^2.1.9, flutter_test from sdk is forbidden.

I faced the same issue. Couldn't find the specific reason for the flutter_test depending on a specific version of this image library. Maybe it's an issue from the flutter side. So here are some workaround solutions:

  1. comment out the flutter_test dev_dependency.

    dev_dependencies: # flutter_test: # sdk: flutter

  2. set the required version.

    Instead of 2.1.12, I set the Image package version to 2.1.4 (as requested in the error message)

    image: ^2.1.4

  3. If more than one packages versions are noncompatible to each other, and you don't know their exact compatible version, you can find it by setting both the conflicting dependencies to any, e.g.

    flutter_crashlytics: any firebase_core: any

    This will automatically figure out the compatible package version. Check these new compatible versions in pubspec.lock file, which will be auto-generated by running flutter package get.

    # Generated by pub # See https://www.dartlang.org/tools/pub/glossary#lockfile packages: flutter_crashlytics: ... version: "1.0.0" firebase_core: ... version: "0.4.2+1"

    Replace any with those correct versions.

    flutter_crashlytics: 1.0.0 firebase_core: 0.4.2+1

Note: You should never leave your versions as any
