How can I determine in what mode my pub transformer works?

Question

I am writing a pub transformer for Dart. I would like the transformer to know in what mode the pub is working (debugging or something else). Can the Transformer tell in what mode it works? And if so, how?

Answer 1

Transformers can have different constructors. One of the constructors can accept objects BarbackSettingsthat contain a mode.

For instance:

class DartToJsScriptRewriter extends Transformer {
  bool releaseMode = false;

  DartToJsScriptRewriter.asPlugin(BarbackSettings settings)
      : releaseMode = (settings.mode == BarbackMode.RELEASE);
