# resolvePackageUri static method

Future<Uri?> resolvePackageUri(

1. Uri packageUri

)

Resolves a `package:` URI to its actual location.

Returns the actual location of the file or directory specified by the `packageUri` `package:` URI.

If the `packageUri` is not a `package:` URI, it's returned as-is.

Returns `null` if `packageUri` is a `package:` URI, but either the current package configuration does not have a configuration for the package name of the URI, or the URI is not valid (doesn't start with `package:valid_package_name/`),

A `package:` URI is resolved to its actual location based on a package resolution configuration (see packageConfig) which specifies how to find the actual location of the file or directory that the `package:` URI points to.

The actual location corresponding to a `package:` URI is always a non-`package:` URI, typically a `file:` or possibly `http:` URI.

A program may be run in a way where source files are not available, and if so, the returned URI may not correspond to the actual file or directory or be `null`.

## Implementation
