Pod install error on M1 Mac - Flutter project with native code like shared_preferences

Question

I'm on a MacBook Pro M1 (and before someone says well it's because of M1 or something else, I've been programming with Flutter and M1 for weeks but then I must have to reset my M1 and after this) ... my big problem:

I can not start my project with a package that include native codes like shared_preferences or sqlite, every time I get a error running Pod Install.

I searched on Stack Overflow and so far nothing helped me. If I start my project without the package there are no problems, this is my Flutter code very simple:

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart';
import 'package:shared_preferences/shared_preferences.dart';

void main() {
 runApp(MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Home(),
    );
  }

}


`class Home extends StatelessWidget {
  const Home({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: RaisedButton.icon(
          onPressed: ()async{
            final prefs = await SharedPreferences.getInstance();
            if(prefs.containsKey("test")){
              print("available");
            }else{
              await prefs.setInt("test", 1);
            }
            final send = await post("xxx",body: {
              "query":"SELECT * FROM NEWS"
            });
            print(json.decode(send.body));
          },
          icon: Icon(Icons.person),
          label: Text("Hii")
        ),
      ),
    );
  }
} ,

This is the error I get from Flutter:

Error output from CocoaPods:
↳
    [!] Automatically assigning platform `iOS` with version `12.0` 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`.

I edited my Podfile and specified a platform but nothing helped. Here are some details:

Flutter Version = 1.22.5 (I tried also the newest version 1.22.6)
Xcode Version = 12.3 (I tried also the newest version 12.4)
Cocoa-pods  = 1.10.0 ((I tried also the newest version 1.10.1)

I installed and reinstalled many times Cocoa-pods it didn't help either

Answer 1

Instead of pod install, you need to do:

arch -x86_64 pod install     

Cocoapods still doesn't have full Apple Silicon support. Running commands with arch -x86_64 forces Terminal to use Rosetta 2 instead.

If that doesn't work, try following this article.

Answer 2

Run this command :

arch -x86_64 sudo gem install ffi

After that, do your flutter build ios --no-codesign or whatever It will work fine.

More info is provided here https://github.com/flutter/flutter/issues/70796#issue-746115543

Answer 3

for me none of these flutter run, flutter build ios, arch -x86_64 pod install and etc does not work until I did these steps:

1. run sudo gem install ffi in terminal.
2. then flutter build ios --release. and worked fine.

Answer 4

Run

sudo gem uninstall ffi 

and

sudo gem install ffi -- --enable-libffi-alloc
