stepFor method

@override CommandStep? stepFor(FormulaAction action, String osName)

Returns the command template for action on osName, or null if the action is unsupported on that platform.

Implementation

@override
CommandStep? stepFor(FormulaAction action, String osName) {
  if (action == FormulaAction.verify) return verifyStep;

  return switch (osName) {
    'linux' => _linuxStep(action),
    'macos' => _brewStep(action),
    // An OS with no packaging story here. `install` never reaches this when
    // the commands are already present — the base class short-circuits on a
    // passing verify — so what is reported is the truth: not supported here.
    _ => null,
  };
