PSPDFKit 3.3 for Flutter Adds Support for Flutter Version 3

PSPDFKit 3.3 for Flutter is out, and it brings a bunch of improvements with it — including support for Flutter 3, and an update to the package import paths. Read on to find out more.

Flutter 3

Flutter version 3 is now supported in PSPDFKit 3.3 for Flutter out of the box on iOS and Android.

Update to Package Import Paths

To follow Flutter best practices and resolve import warnings you might’ve seen, we moved our package files from lib/src to lib. To update your code for this change, follow the migration guide.

The old imports are still available but are now deprecated and will be removed in future releases.

Handling Multiple Initializations

This release also adds the capability to handle errors that may occur when setting the license key. For example, you shouldn’t set the license key multiple times, even after reloading the Flutter application. This exception can be caught with try/catch, as shown below:

try {
  await Pspdfkit.setLicenseKeys("YOUR_FLUTTER_ANDROID_LICENSE_KEY_GOES_HERE",
     "YOUR_FLUTTER_IOS_LICENSE_KEY_GOES_HERE");
} on Exception ctach(_) {
  print("License key could not be set.");
}

And More!

In preparation for the upcoming iOS 16 release, PSPDFKit 3.3 for Flutter now requires iOS 14 or later.

A couple of other notable fixes are that we resolved an issue where tapping on form fields could misbehave in the Catalog basic example, and we fixed the userInterfaceViewMode: 'alwaysHidden' configuration option, which wasn’t hiding the widget’s top bar on iOS.
