Use the package_resolver package.
This allows this to be compatible with package specs as well as package
directories.

+## 1.1.0
+
+* `mapStackTrace()` now uses a `SyncPackageResolver` object from the
+ [`package_resolver` package][package_resolver] to recreate `package:` URIs.
+
+* **Deprecation**: the `packageRoot` parameter to `mapStackTrace` is deprecated
+ in favor of the `packageInfo` parameter described above. It will be removed in
+ a future release.
+
+[package_resolver]: https://pub.dartlang.org/packages/package_resolver
+
## 1.0.5
* Add compatibility for member names that include named arguments.
