I get this error on terminal whenever I try to install pod.

Answer 1

This problem mainly occur when using a MacBook with the M1 chip.

CocoaPods could not find compatible versions for pod "Firebase/Messaging":

In Podfile: firebase_messaging (from .symlinks/plugins/firebase_messaging/ios) was resolved to 10.0.0, which depends on Firebase/Messaging (= 8.0.0)

The Solution here is to try the following steps:

Cocoa Pods Installation in M1

• sudo gem install cocoapods
• sudo gem install ffi
• arch -x86_64 sudo gem install cocoapods -n /usr/local/bin
• sudo gem install cocoapods -n /usr/local/bin

Install ffi

• sudo arch -x86_64 gem install ffi

#update repo

• arch -x86_64 pod install --repo-update

Flutter iOS builds

• flutter clean
• flutter build ios

Re-install dependency in iOS folder of flutter project

• arch -x86_64 pod install

Answer 2

As the error said, we have incompatibility with the firebase package so: I went to the Podfile and upgrade to 10 (platform :ios, '10.0') and the error go away;

as additional note: I had that line commented before, so my first try was uncomment and upgrade to 9, but it wasn't work.
