Nothing happens when clicking on a finished download

Added in version 5.6.0

Adds handler for when the user taps a notification, and an openFile method to open a file using the platform-specific convention.

To handle notification taps, register a callback that takes Task and NotificationType as parameters:

FileDownloader().registerCallbacks(
            taskNotificationTapCallback: myNotificationTapCallback);
            
void myNotificationTapCallback(Task task, NotificationType notificationType) {
    print('Tapped notification $notificationType for taskId ${task.taskId}');
  }

To open a file, call FileDownloader().openFile and supply either a Task or a full filePath (but not both) and optionally a mimeType to assist the Platform in choosing the right application to use to open the file.
The file opening behavior is platform dependent, and while you should check the return value of the call to openFile, error checking is not fully consistent.

Note that on Android, files stored in the BaseDirectory.applicationDocuments cannot be opened. You need to download to a different base directory (e.g. .applicationSupport) or move the file to shared storage before attempting to open it.

If all you want to do on notification tap is to open the file, you can simplify the process by
adding tapOpensFile: true to your call to configureNotifications, and you don't need to
register a taskNotificationTapCallback.
