Debug Crashes in Flatpak Apps

First install debug packages for the app that crashed. Run the following command in a terminal window:

flatpak install --include-sdk --include-debug [app id]

Where [app id] is the ID of the app, like org.kde.okular.

Then get a backtrace of the crash:

flatpak-coredumpctl [app id]

Then follow the normal instructions for using coredumpctl to complete the process of getting a developer-readable backtrace of the crash.
