convert method

Future<List<Future<void> Function()>> convert(List<UserFlowStep> steps)

Converts the steps into a list of executable actions.

Implementation

Future<List<Future<void> Function()>> convert(
  List<UserFlowStep> steps,
) async {
  return Future.wait(
    steps.map((step) async {
      try {
        final action = _registry.getAction(step.actionName, step.arguments);
        final actionRepresentation = action.description();
        await _emitter.announce(actionRepresentation);

        return () async {
          try {
            await _emitter.start(actionRepresentation);
            if (await action.execute(this)) {
              return _emitter.done(actionRepresentation);
            }
            return _emitter.fail(actionRepresentation);
          } catch (err) {
            return _emitter.fail(actionRepresentation, reason: '$err');
          }
        };
      } catch (err) {
        await _emitter.fatal('$err');
        rethrow;
      }
    }).toList(),
  );
