PackageAssetReader class

Resolves using a PackageConfig before reading from the file system.

For a simple implementation that uses the current isolate's package resolution logic (i.e. whatever you have generated in .dart_tool/package_config.json in most cases), use currentIsolate:

var assetReader = await PackageAssetReader.currentIsolate();

Doesn't implement AssetReader: for cases that need an AssetReader, use this class to read the files then write them into a TestReaderWriter. To copy all the sources see TestReaderWriter.testing.loadIsolateSources.

Constructors

PackageAssetReader(PackageConfig packageConfig, [String? _rootPackage])

Wrap a PackageConfig to identify where files are located.

PackageAssetReader.forPackageRoot(String packageRoot, [String? rootPackage])

A PackageAssetReader with a single packageRoot configured.

factory

PackageAssetReader.forPackages(Map<String, String> packageToPath, [String? rootPackage])

Returns a PackageAssetReader with a simple packageToPath mapping.
