Illinois App

The official mobile app of the University of Illinois. Powered by the Rokwire Platform.

Requirements

Flutter v3.3.2

Android Studio 2021.3.1+

xCode 14.2

CocoaPods 1.11.3+

Build

Clone this repo

git clone --recurse-submodules https://github.com/rokwire/illinois-app.git

Make sure app flutter plugin persists

Rokwire app flutter plugin is used by the Illinois app. It should be located in the plugin subdirectory of the application's root project directory. If it does not exist you need to clone it manually.

cd illinois-app.git
git clone https://github.com/rokwire/app-flutter-plugin.git plugin

Supply the following private configuration files:

• .travis.yml

Obsolete, not used after version 2.0 inclusive.

• secrets.tar.enc

Obsolete, not used after version 2.0 inclusive.

• assets/config.keys.json (for versions after 3.0 inclusive)

JSON data with the following format:

{
	"key":"...",
	"iv":"..."
}

key and iv fields contain strings that are base64 encoded randomly generated 16-bytes AES128 key and IV. These keys are used for decryption of assets/configs.json.enc from the application assets as well as for the decryption of secretKeys enctypted string in app config.

• assets/configs.json.enc

1. JSON data with the following format:

{
  "production": {
    "config_url": "https://api.rokwire.illinois.edu/app/configs",
    "api_key": "XXXXXXXX-XXXX-XXXX-XXXXXXXXXXXXXXXXX"
  },
  "dev": {
    "config_url": "https://api-dev.rokwire.illinois.edu/app/configs",
    "api_key": "XXXXXXXX-XXXX-XXXX-XXXXXXXXXXXXXXXXX"
  },
  "test": {
    "config_url": "https://api-test.rokwire.illinois.edu/app/configs",
    "api_key": "XXXXXXXX-XXXX-XXXX-XXXXXXXXXXXXXXXXX"
  }
}

2. For versions prior to 3.0:
   • Generate random 16-bytes AES128 key.
   • AES encrypt the JSON string, CBC mode, PKCS7 padding, using the AES.
   • Create a data blob that contains the AES key at the beginning followed by the encrypted data.
   • Get a base64 encoded string of the data blob and save it as assets/configs.json.enc.

Alternatively, you can use AESCrypt.encode from /lib/utils/Crypt.dart to generate content of assets/configs.json.enc.

3. For versions after 3.0 inclusive:
   • AES encrypt the JSON string, CBC mode, PKCS7 padding, using the key and IV from assets/config.keys.json.
   • Get a base64 encoded string of the encryption result and save it as assets/configs.json.enc.

Build the project

$ sh ./scripts/prebuild_illinois.sh
$ flutter build apk --no-tree-shake-icons --flavor IllinoisProd -t lib/mainProd.dart
$ flutter build apk --no-tree-shake-icons --flavor IllinoisDev -t lib/mainDev.dart
$ flutter build apk --no-tree-shake-icons --flavor IllinoisTst -t lib/mainTest.dart

$ flutter build ios --no-tree-shake-icons --flavor IllinoisProd -t lib/mainProd.dart
$ flutter build ios --no-tree-shake-icons --flavor IllinoisDev -t lib/IllinoisDev.dart
$ flutter build ios --no-tree-shake-icons --flavor IllinoisTst -t lib/mainTest.dart

NB: Product environments: Prod/Dev/Test

--flavor IllinoisProd -t lib/mainProd.dart
--flavor IllinoisDev -t lib/mainDev.dart
--flavor IllinoisTst -t lib/mainTest.dart

NB: For versions prior to 4.2 you may omit the no-tree-shake-icons build parameter.

NB: You may need to update singing & capabilities content for Runner project by opening ios/Runner.xcworkspace from xCode
