Flutter project failing to build on Mac M1

Question

I have recently bought a new Mac book with the M1 chip and faced huge issues between Flutter and Firebase in building. I will list both the Flutter error log and Xcode error log.

Note: I'm building on Flutter channel Master

Flutter Error Log:

    Launching lib/main.dart on iPod touch (7th generation) in debug mode...
    Xcode build done.                                           69.1s
    Failed to build iOS app

Error output from Xcode build:

objc[30795]: Class AMSupportURLConnectionDelegate is implemented in both ?? (0x1fe91f8f0) and ?? (0x1189402b8). One of the two will be used. Which one is undefined.
objc[30795]: Class AMSupportURLSession is implemented in both ?? (0x1fe91f940) and ?? (0x118940308). One of the two will be used. Which one is undefined.
** BUILD FAILED **

Xcode's output:

This is the main error, there were many warning, but I'm not sure if they're causing the build failure.

Answer 1

i had another issue related to flutter dependency that showing error OBJC_CLASS on firebase dependency, image cropper, stripe, etc.

My xcode disable archive & distribute menu because no successful build to archive. I resolved it with this idea: build the app on terminal/android studio, then archive & distribute on xcode.

The step is:

uninstall cocoapods

sudo gem uninstall cocoapods

install brew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

nano ~/.zshrc

export PATH="/opt/homebrew/bin:$PATH"

brew --version

install cocoapods

brew install cocoapods

pod --version

link xcode

flutter doctor

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

sudo xcodebuild -runFirstLaunch

go to your flutter project and

flutter clean flutter pub get cd ios pod install pod update

open Runner.xcworkspace with xcode and set your signing & capabilities

open terminal on your flutter project and build

flutter build ios --release

This will build Runner.app

Go to xcode, on Runner choose any ios device (arm64), to enable archive.

Then

product-> archive->distribute app->next->manual signin->set your certificate distributor

This will build your .ipa

Answer 2

As we know that m1 mac runs on arm based processor and thus few things like cocoa pods and ffi needs to be build based on that. After a long research i came up with few steps which will definitely help everytime you stuck with xcode flutter application build for m1 mac.

To install completely cocoapods on Mac with M1 chip (Apple Silicon), please follow those 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 3

I removed all depreciations and the project ran perfectly.

Answer 4

I also have an M1 Mac, and am on the stable channel, without any errors.

Try switching to stable first.

Also, try running $ flutter clean and again building the app.
