Flutter gives error "Error running pod install" - flutter

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:
Launching lib/main.dart on iPhone 13 in debug mode...
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.

Answer 1

Use these commands in your project files to manually install pod files:
cd ios
arch -x86_64 pod install
cd ..
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'

Answer 3

I had the same problem
Here is my solution.
open 'ISO foler' with Xcode
click Runner folder at top, and copy bundle identifier
go to firebase website and start IOS connection
paste the copied identifier and click next
download the plist file and move to runner folder
go to ios folder
arch -x86_64 pod install
cd ..
flutter run
The point is that you should manually connect firebase to flutter. I used the flutter connection thing that firebase recently added. But it has some glitch I guess.

Answer 4

which can solve the probe
