Dart

How json2vars-setter handles Dart, and how the example workflow provisions it.

json2vars-setter integration

Item Value
Matrix JSON key versions.dart
Action output versions_dart
Dynamic-update strategy input dart-strategy (stable / latest / both)
Version source see Version Sources

Supported runners

The example matrix runs on Ubuntu / Windows / macOS:

ubuntu-latest, windows-latest, macos-latest

Any GitHub-hosted runner the setup action supports also works - the OS list is just the os array in your matrix JSON.

Supported versions

Example matrix (what the example workflow runs):

{
  "versions": {
    "dart": [
      "3.11.6",
      "3.12.1"
    ]
  }
}

Latest values tracked by the dynamic-update tooling (auto-refreshed from the release APIs into the version cache):

Field Version
stable 3.11.6
latest 3.12.2
