Flutter Firebase - Use of undeclared identifier 'FIRAnalytics'

Question

I am working on a flutter project on my M3 Macbook and trying to implement FirebaseAnalytics (not first time btw). I followed th guide completely and I got the error;

I tried to clean cache of pub, xcode and simulator. Also upgraded my flutter version from 3.16.9 to 3.19.0. Also tried every single solution request from StackOverflow and Github but no luck. here is my firebase package dependencies;

pubspec.yaml

environment:
  sdk: '>=3.2.6 <4.0.0'

dependencies:
  firebase_analytics: ^10.8.6
  firebase_core: ^2.22.0
  firebase_messaging: ^14.7.15

doctor:

Answer 1

After trying multiple ways (updating os, cleaning the cache, importing package manually etc.) to overcome this issue realized that cocoapods has a new version. I was using 1.15.1. After updating cocoapods with following command:

sudo gem install cocoapods

Cleared the cache with

pod cache clean --all

Removed following files and folders under ios

.symlinks
Pods
Podfile.lock

and then I installed all pods under project with

pod install

After all it built normally.

I hope it will be useful
