How to Solve Class AMSupportURLConnectionDelegate is implemented in both Error?

Solution 1 : Flutter clean

I Solved this error by following command.

1. flutter clean inside the project directory.
2. then run app
3. flutter build ios
4. Your error maybe solved.

Solution 2 : flutter build ios –verbose

This error also occurs when you have an error in your code that may be not visible error just like profile is missing or something like that. so that you have to find that error first So, please run flutter build ios --verbose and read the output carefully.

In my case, there were other issues of the failure of flutter build ios. Problem was I forgot to add GoogleService-Info.plist in runner folder and also my ios deployment target was less than the requirement of flutter packages.

Solution 3 : Rebuild project

If You have no any solution then just rebuild project.

1. rebuild new flutter project
2. open terminal
3. move to ios directory (project)
4. pod init
5. pod install
6. modify ios/Podfile file as this content

Solution 4 : Pod Install

I’ve fixed the issue by doing this. hope it will work for you also

cd ios
pod init
pod install

Solution 5

Normally it is working after these steps

1. flutter clean
2. flutter pub get
3. cd ios
4. pod install
5. cd ..
6. flutter buid ios

This time it worked for me with an additional command flutter upgrade pub as I was using the newer user of flutter with old pub file. I hope it may help someone using M1 processor.
