Can not validate flutter ios ipa in Xcode 12

[nimishthorat]

I am trying to upload my flutter app to App store. All phases till creating Archive goes smoothly. But when I try to validate or distribute app, while analysing my ipa I get error:

I checked that my apps bundle identifier and bundle identifier on app store are same. I am using firebase messaging plugin. And protobuf is installed with firebase messaging pod. So what I don't understand is that how a frameworks bundle identifier is causing my upload failure.
Can please anyone help?
