**Q:** I updated the Flutter library and I’m getting the following error:

```bash

lib/main.dart:8:8: Error: Error when reading '../../.pub-cache/git/pspdfkit-flutter-b6241555b1ee3e816a0dce65145991c1a4477d94/lib/pspdfkit.dart': No such file or directory

```

**A:** If you were using version [1.10.3](https://github.com/PSPDFKit/pspdfkit-flutter/releases/tag/1.10.3) or earlier, you'll need to update the imports in your Dart files, like so:

```diff

-import 'package:pspdfkit_flutter/pspdfkit.dart';
+import 'package:pspdfkit_flutter/src/main.dart';

```
