Build Status


Allows wrapping up a Builder as a Transformer so that it can be run in pub or vice-versa.

Using a Builder from Pub

Wrap the Builder instance with new BuilderTransformer(builder) and use it like any other Transformer. The Builder used this way must follow the rules of other Transformers, it cannot use inputs from outside the package where the Transformer is specified in pubspec.yaml

Using an exisiting Transformer with package:build

Wrap the Transformer instance with new TransformerBuilder(transformer) and run as any other Builder. The Transformer instance used this way must follow the rules of other Builders:

  • It cannot overwrite files it uses as inputs.
  • It must know before building what the outputs will be (it must be a DeclaringTransformer).
