Flutter iOS Error Class AMSupportURLConnectionDelegate is implemented in both /usr/lib/libamsupport.dylib (0x203913130)

Hi am facing an issue while running flutter project in MacBook Air M1 chip Lap. Tried all possibilities couldn't find where is the exact problem.

All basic solutions like flutter clean, flutter pub get, pod deintegrate & install, flutter build ios, flutter run but still same issue. only on iOS simulator not deploying.

Any solution for this. Thanks in advance.

Solution

I've done complete clean and install by below steps and it helped me to solve,

Step 1:

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
rm ios/Podfile

Step 2:

cd ios
flutter pub get
pod cache clean --all
pod install

    or  (below for m1 chip incase above command thrown error in pod install)

#1 Install ffi
sudo arch -x86_64 gem install ffi

#2 Re-install dependencies
arch -x86_64 pod install

Step 3:

1. Open ios/Pods/Pods.xcodeproj in Xcode
2. Change the iOS Deployment info from 8.0 to 9.0

Step 4:

From xcode clean / build again / run. Hope this should work. Before please confirm whether all the build settings for iOS configured properly or not.

Note: In those above steps i faced one more issue from Firebase like "firebase import not found". Below added steps how i solved.

Step 1: open ios/Podfile

Check platform :ios, '10.0' is uncommented

Step 2:

add below code at end of Podfile

target 'CustomImageNotifications' do
  use_frameworks!
  pod 'Firebase/Analytics'
  pod 'Firebase/Messaging'
end

Step 3: pod install & open xcode and clean / build.

Hoping this answer may helps.! thanks
