pub_mediator

Diagnoses version conflicts between dependencies in Dart packages.

About

Without mediator, it is rather cumbersome to resolve dependency conflicts within Dart projects. You would receive a relatively cryptic error message that doesn't tell you much in the way of resolving conflicts:

Package jaguar_serializer has no versions that match >=0.3.0 <0.4.0 derived from:
- gitter 0.1.1 depends on version ^0.3.0

mediator provides you with details about where the mismatches are:

✗ Found 1 dependency conflict:
Found 2 mismatching dependencies on package:crypto:
  * foo requires  <1.0.0
  * angel_auth requires  ^2.0.0

mediator also tracks nested dependencies. Dependency mismatches don't always happen at the top level, but often within the dependencies of other dependencies.

✗ Found 1 dependency conflict:
Found 2 mismatching dependencies on package:crypto:
  * foo requires  <1.0.0
  * bar->baz->quux requires  ^2.0.0
