BuildStep class Null safety

A single step in a build process.

This represents a single inputId, logic around resolving as a library, and the ability to read and write assets as allowed by the underlying build system.

Methods

canRead(AssetId id) Future<bool>
Indicates whether asset at id is readable.
inherited
digest(AssetId id) Future<Digest>
Returns a Digest representing a hash of the contents of id. [...]
inherited
fetchResource<T>(Resource<T> resource) Future<T>
Gets an instance provided by resource which is guaranteed to be unique within a single build, and may be reused across build steps within a build if the implementation allows. [...]
findAssets(Glob glob) Stream<AssetId>
Returns all readable assets matching glob under the current package.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
readAsBytes(AssetId id) Future<List<int>>
Returns a Future that completes with the bytes of a binary asset. [...]
inherited
readAsString(AssetId id, {Encoding encoding = utf8}) Future<String>
Returns a Future that completes with the contents of a text asset. [...]
inherited
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
Tracks performance of action separately. [...]
writeAsBytes(AssetId id, FutureOr<List<int>> bytes) Future<void>
Writes bytes to a binary file located at id. [...]
override
writeAsString(AssetId id, FutureOr<String> contents, {Encoding encoding = utf8}) Future<void>
Writes contents to a text file located at id with encoding. [...]
override

Operators

operator ==(Object other) bool
The equality operator. [...]
