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

FAILURE: Build failed with an exception.

A: If you were using version 1.10.3(opens in a new tab) or earlier, you'll need to update the imports in your Dart files, like so:

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