Flutter gives error "Error running pod install"

Question

I get the below error/log when i implement the google_sign_in package to my flutter application. I'm using m1 chip. all the packages, flutter framework and xcode at their last versions.

Flutter project dependencies:

• http: ^0.13.4
• firebase_auth: ^3.3.6
• google_sign_in: ^5.2.3

At the first i got this:

    Error output from CocoaPods:
    ↳
        [!] Automatically assigning platform `iOS` with version `9.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

Then I've uncomment this platform :ios, '9.0' at ios/Podfile

But different error shows up like this:

    lib/main.dart:1

    ...

I think because of the m1 chip that i using, according to this error message (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')) Does anyone have an idea about this issue?

Also, the below subjects' answers didn't work for me.

Flutter Error running pod install After Upgrading Flutter version

Flutter pod install issue and ios app not running

https://github.com/CocoaPods/CocoaPods/issues/10127#issuecomment-705741320

Answer 1

Use these commands in your project files to manually install pod files:

1. cd ios

2. arch -x86_64 pod install

3. cd ..

4. flutter run

Answer 2

run this code on your terminal

sudo arch -x86_64 gem install ffi

Next, go to the ios folder in your project, and open Podfile.

Change the 9.0 to 10.0, as the below

platform :ios, '10.0'
