Constructors
- SystemCache({String? rootDir, bool isOffline = false})
- Creates a system cache and registers all sources in sources.

describe(
PackageId id) → Future< Pubspec> -
Loads the (possibly remote) pubspec for the package version identified by
id. -
downloadPackage(
PackageId id) → Future< DownloadPackageResult> -
Downloads a cached package identified by
idto the cache. -
getDirectory(
PackageId id, {String? relativeFrom}) → String - Returns the directory where this package can (or could) be found locally.
-
getLatest(
PackageRef? package, {Version? version, bool allowPrereleases = false}) → Future< PackageId?> -
Get the latest version of
package. -
getVersions(
PackageRef ref, {Duration? maxAge, Version? allowedRetractedVersion}) → Future< List< PackageId> > -
Get the IDs of all versions that match
ref. -
load(
PackageId id) → Package -
Loads the package identified by
id. -
loadCached(
PackageId id) → Package -
maintainCache(
) → void - Tasks that ensures the cache is in a good condition. Should be called whenever an operation updates the cache.
