# uri_does_not_exist_in_doc_import

> Details about the uri_does_not_exist_in_doc_import diagnostic produced by the Dart analyzer.



_Target of URI doesn't exist: '{0}'._

## Description

The analyzer produces this diagnostic when a doc-import is found where
the URI refers to a file that doesn't exist.

## Examples

If the file `lib.dart` doesn't exist, the following code produces this
diagnostic:

```dart
/// @docImport [!'lib.dart'!];
library;
```

## Common fixes

If the URI was mistyped or invalid, then correct the URI.

If the URI is correct, then create the file.
