buildExtensions property

Map<String, List<String>> get buildExtensions

Mapping from input file extension to output file extensions.

All input sources matching any key in this map will be passed as build step to this builder. Only files with the same basename and an extension from the values in this map are expected as outputs.

• If an empty key exists, all inputs are considered matching.
• An instance of a builder must always return the same configuration. Typically, a builder will return a const map. Builders may also choose extensions based on BuilderOptions.
• Most builders will use a single input extension and one or more output extensions.
• For more information on build extensions, see https://github.com/dart-lang/build/blob/master/docs/writing_a_builder.md#configuring-outputs
