Flutter: Could not install build/ios/iphoneos/Runner.app

When running flutter apps on the device, sometimes you may encounter the captioned error message as following (either from Android Studio, Intelligidea or CLI):

Could not install build/ios/iphoneos/Runner.app

To resolve this, try below measures, preferably sequentially in terminal:

cd "$(xcrun --sdk iphoneos -- show-sdk-platform-path)/DeviceSupport"
sudo ln -s 10.3.1\ \(14E8301\) 10.3

After running these commands, it should work fine, and if not, try run this command below in terminal:

flutter clean

The reason of running this is to clean the build since it is possible that the old build is still in effect and a clean build removes the legacy generated files.

Re-run the app, now it works like a charm.
