BuildStep class abstract

A single step in build_runner build.

See the Builder class API for more information on what causes build steps to run during a builder. The Builder class has a build method that accepts a BuildStep and uses it to read inputs, resolve Dart source and write outputs.

Methods

canRead(AssetId id) → Future<bool>
Indicates whether id can be read by this build step.
override
digest(AssetId id) → Future<Digest>
Returns a Digest representing a hash of the contents of id.
inherited
fetchResource<T>(Resource<T> resource) → Future<T>
Fetches resource.
findAssets(Glob glob) → Stream<AssetId>
Returns all readable assets matching glob under the current package.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
readAsBytes(AssetId id) → Future<List<int>>
Reads the bytes from id.
override
readAsString(AssetId id, {Encoding encoding = utf8}) → Future<String>
Reads the text contents of id using encoding.
override
reportUnusedAssets(Iterable<AssetId> ids) → void
Indicates that ids were read but their content has no impact on the outputs of this step.
toString() → String
A string representation of this object.
inherited
trackStage<T>(String label, T action(), {bool isExternal = false}) → T

writeAsBytes(AssetId id, FutureOr<List<int>> bytes) → Future<void>
Writes bytes to id.
override
writeAsString(AssetId id, FutureOr<String> contents, {Encoding encoding = utf8}) → Future<void>
Writes contents to id using encoding.
