build library Null safety
Classes
- AssetId
- Identifies an asset within a package.
- AssetReader
- Standard interface for reading an asset within in a package. [...]
- AssetWriter
- Standard interface for writing an asset into a package's outputs.
- AssetWriterSpy
- An AssetWriter which tracks all assetsWritten during its lifetime.
- Builder
- The basic builder class, used to build new files from existing ones.
- BuilderOptions
- BuildStep
- A single step in a build process. [...]
- FileDeletingBuilder
- A PostProcessBuilder which can be configured to consume any input extensions and always deletes it primary input.
- MultiPackageAssetReader
-
The same as an
AssetReader, except thatfindAssetstakes an optional argumentpackagewhich allows you to glob any package. [...] - MultiplexingBuilder
- A Builder that runs multiple delegate builders asynchronously. [...]
- PostProcessBuilder
- A builder which runs in a special phase at the end of the build. [...]
- PostProcessBuildStep
- A simplified BuildStep which can only read its primary input, and can't get a Resolver or any Resources, at least for now.
- ReleasableResolver
- A resolver that should be manually released at the end of a build step.
- Resolver
- Standard interface for resolving Dart source code as part of a build.
- Resolvers
- A factory that returns a resolver for a given BuildStep.
-
Resource<
T> - A Resource encapsulates the logic for creating and disposing of some expensive object which has a lifecycle. [...]
- ResourceManager
- Manages fetching and disposing of a group of Resources. [...]
- StageTracker
Extensions
- BuildOutputExtensions
- Extensions on Builder describing expected outputs.
