Answer 1

navigate to ios directory then Run these commands

cd ios (navigate to ios directory)
flutter precache --ios
pod install 

Answer 2

in your pod file,

# platform :ios, '9.0'

uncomment this line and change 9.0 to 10.0 and run the app. it will take some time at the first. like 20 - 30 minutes.

Answer 3

I have resolved this issue, the issue with the podfile hence I have run the following command and it works.

sudo gem install cocoapods
