Flutter IOS error: error: no such module 'flutter_config' - ios

Question

I'm having issue when trying to build my flutter project on code magic CI. I'm using Flutter 2.2.3(same issue also happens on 2.8) and Xcode version 12.4(same issue on 13.2)
/Users/builder/clone/ios/Runner/AppDelegate.swift:5:8: error: no such module 'flutter_config'
import flutter_config

Encountered error while building for the device.
When launching the app locally I'm having another error:

Answer 1

In your ios/Podfile file, uncomment the platform line and give it a value of 11
# Uncomment this line to define a global platform for your project
platform :ios, '11.0'
Make sure to make the change in your Xcode as well
Then in your ios directory, run the following commands
rm -rf Pods/
rm -rf Podfile.lock
pod install
