Running integration testing for Flutter on Azure Devops pipeline for UI automation testing

To achieve what i wanted to do, i instead created a file with the below code and added script capability pushed it to the project

# DO NOT RUN ON YOUR LOCAL MACHINE
echo "install xcode in command line"
xcode-select --install
echo "install home brew"
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
echo "install flutter using brew"
brew install --cask flutter
echo "starting up apple emulator"
flutter emulators --launch <apple_ios_simulator/android emulator>
echo "awaiting for emualator to load"
sleep 5
echo "starting integration tests"
flutter drive --target=test_driver/<yourtestfile>.dart

call this in your azure-pipeline yml as a bash script via drag and drop from the side-panel of your dev ops. Run it and you will see it work. Some limitations are when it comes to system dialog boxes on the android/ios emulators which requires user permission, you can follow it here. For iOS there is a tool called AppleSimulatorUtils
