PackageResolver class
A class that defines how to resolve package: URIs.
This includes the information necessary to resolve package: URIs using
either a package config or a package root. It can be used both as a standard
cross-package representation of the user's configuration, and as a means of
concretely locating packages and the assets they contain.
Unlike SyncPackageResolver, this does not provide synchronous APIs. This is necessary when dealing with the current Isolate's package resolution strategy.
This class should not be implemented by user code.
Constructors
-
PackageResolver.config(Map<
String, Uri> packageConfigMap, {dynamic uri}) -
Returns the package resolution strategy for the given
packageConfigMap. [...]factory - PackageResolver.root(dynamic packageRoot)
-
Returns the package resolution strategy for the given
packageRoot, which may be aStringor aUri.factory
Properties

processArgument
→ Future<
String> -
Returns the argument to pass to a subprocess to get it to use this package
resolution strategy when resolving
package:URIs. [...]read-only - runtimeType → Type

-
Returns package resolution strategy describing how the current isolate
resolves
package:URIs.final - none → PackageResolver
-
Returns a package resolution strategy that is unable to resolve any
package:URIs.final

-
loadConfig(
dynamic uri, {Client client}) → Future< PackageResolver> -
Loads a package config file from
uriand returns its package resolution strategy. [...]
