Because every version of flutter_test from sdk depends on... flutter_test from sdk is forbidden, version solving failed

Question

I'm having this issue when I've added http dependency in my flutter project. Can anyone please help me with it?

Answer 1

If you get the message:

Because every version of flutter_test from sdk depends on...

It means flutter_test depends on a dependency with version lower than you specified in another dependency.

To solve this, open pubspec.yaml, and remove the version number of the problem dependency:

Example:

Change

  archive: ^2.0.13 --> remove this number

To:

  archive:

You have provided or trying to use http: ^0.12.0 dependency on implementing API calls in pubspec.yaml file but flutter_test will require http: ^0.11.3+17. That's why it fails. Please replace

dependencies:
  flutter:
    sdk: flutter
  http: ^0.12.0

with

dependencies:
  flutter:
    sdk: flutter
  http: ^0.11.3

Hope it will help you out.

In my case, I somehow deleted sdk: flutter:

dependencies:
  flutter:
    sdk: flutter
