Enable constraintsFiltering for pub

[matthewnitschke-wk]

Tell us more.

Currently the pub manager does not support constraintsFiltering. Meaning if your pubspec contains an environment field, renovate will happily bump dependencies that no longer meet this environment constraint

name: some_package
environment:
  # this specific package doesn't support dart 3 yet
  sdk: '>=2.19.0 <3.0.0'

dependencies:
  # renovate will try to bump args to `2.7.0` which is only supported in dart 3
  args: ^2.3.1 

Without knowing too much about renovate's internals, I don't anticipate this being too difficult to implement. The pub apis do already include environment data in pubspec.environment, and it should be fairly easy to leverage the existing constraintsFiltering infrastructure for this manager

constraintsFiltering for pub would be quite helpful, as in dart, its a common practice to bump minimum dart sdk versions as minors breaking renovate PRs

Update

This has been implemented: #44171

If you have an example of a specific package that we can test this with, that'd be appreciated!

Here you go! https://github.com/matthewnitschke-wk/renovate_pub_constraintFiltering

At a high level:

• constraintsFiltering globally enabled
• rangeStrategy: bump to tell renovate to bump to the latest versions of things
• renovate PR bumping to an incompatible version

@jamietanna I've gone ahead an thrown together an implementation of this here: #44171

Please let me know if you'd like anything changed, or would otherwise like to handle this feature request differently
