[YawarOsman]

hello all,
I'm using flutter with firebase to create a restaurant web base system, and my issue is: firebase offline mode doesn't work for me and when i try to enable it by firestore.enablePersistence(); it shows this error down below:

It don't show any error in the console.

i enabled it by this code await FirebaseFirestore.instance.enablePersistence(); before using any firebase classes.
