I have a matrix like this:
strategy:
fail-fast: false
matrix:
os: [ubuntu-latest, windows-latest, macOS-latest]
node-version: [10]
dart-version: [stable, dev]
code-version: [stable, insiders]
I would like to only run the dev-dart and insiders-vscode builds for the master branch, and have only the stable/stable versions run for other branches. I can’t find a way to make these values conditional (either here, or by using exclude).
