documentation improvement if time permitting?

i have flutter configured in android studio where new project build and runs in iphone x simulator, but when i check out the project, tell it where flutter sdk is, and try to build it fails with

Could not build the application for the simulator. Error launching application on iPhone X.

The app throws the following error:

I am using Flutter SDK v1.0 stable, and here are the dependencies versions I have in the pubspec.yaml:

http: ^0.11.3+16 sqflite: ^0.13.0
path_provider: "^0.4.1" redux: '^3.0.0' flutter_redux: '^0.5.2'

cupertino_icons: ^0.1.2 rxdart: 0.19.0

The following error occurs.

How should I fix it?
