 # Resource
 
+----
+**NOTICE** This package is **discontinued**.
+It will not be maintained or upgraded in the future.
+
+This package combines two functionalities:
+* Converting a `package:` URI to a platform specific URI
+  (usually `http:` or `file:`, depending on the platform)
+* Load the contents of such platform specific URIs.
+
+The former no longer makes sense when a large number of Dart
+programs are ahead-of-time compiled.
+Those programs do not have access to *source* files at runtime,
+and a `package:` URI references a source file.
+There is no standard way to find a *runtime* location of a source file,
+or even ensure that it is available.
+
+The platform specific loading functionality can still be useful.
+However, without a way to produce such platform specific URIs from
+platform independent ones, the only URIs which can still
+be loaded on all platforms are `http:`/`https:` ones.
+Loading those is *better* supported by the [`http` package][package:http].
+
+As such, this package can no longer supports its original goal,
+being a *cross platform* resource loading solution.
+It will be discontinued rather than provide an inadequate solution.
