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

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.

upgrade to 10 (platform :ios, '10.0') its work but face another issue

cloud_firestore: ^0.16.0

Error: CocoaPods's specs repository is too out-of-date to satisfy dependencies.

Solution

It can be solved by executing the following commands in the terminal.

  1. Go to /ios folder inside your Project.

  2. Delete Podfile.lock

  3. Run pod install --repo-update (Make sure your cd into the iOS directory of the flutter app)

  4. Run flutter clean

  5. Once complete, rebuild your Flutter application: flutter run

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

Thank you for the answer! It took quite some time to figure this out. For those looking and using Visual Studio Code. After you run the debugger, and Podfile will be created for you. At the top of the Podfile file in the ios/ directory, uncomment the line to read: platform :ios, '10.0'
