# invalid_uri

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



_Invalid URI syntax: '{0}'._

## Description

The analyzer produces this diagnostic when a URI in a directive doesn't
conform to the syntax of a valid URI.

## Example

The following code produces this diagnostic because `'#'` isn't a valid
URI:

```dart
import [!'#'!];
```

## Common fixes

Replace the invalid URI with a valid URI.
