CocoaPods could not find compatible versions for pod "Firebase/Analytics"

I'm new to React-Native and developing a project. Previously, it was working fine but when I installed Push Notification (rnfirebase for messaging) related dependencies, I'm getting these errors and I also tried all possible solutions from other questions too but no success.

Here is the complete errors which I'm getting while pod installation.

[!] CocoaPods could not find compatible versions for pod "Firebase/Analytics":
  In snapshot (Podfile.lock):
    Firebase/Analytics (= 6.13.0)

  In Podfile:
    Firebase/Analytics

RNFBMessaging (from `../node_modules/@react-native-firebase/messaging`) was resolved to 7.1.5, which depends on
  Firebase/Analytics (~> 6.25.0)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `Firebase/Analytics` inside your development pod `RNFBMessaging`.
   You should run `pod update Firebase/Analytics` to apply changes you've made.

This is the code in the pod file.

# add the Firebase pod for Google Analytics
  pod 'Firebase/Analytics'
  # pod 'Firebase/Auth'
  pod 'Fabric', '~> 1.10.2'
  pod 'Crashlytics', '~> 3.14.0'
  # add pods for any other desired Firebase products
  # https://firebase.google.com/docs/ios/setup#available-pods

I tried the following workaround to resolve this issue.

1. pod install --repo-update

2. pod repo remove master 
   pod setup 
   pod install

3. Delete podfile.lock
   pod install

But none solution worked for me. Can anyone please help me to resolve this issue? I will really appreciate it.
