This app is the main client used for printing with AStAPrint/PAStA.
Through it users can register themselves, load credit on their account and upload docuemnts they want to print. It also offers modes to get documents you scan from a printer and optionally direct-print them for a 'copy' mode.
To get the last running dependency configuration run flutter packages get, if you want the latest versions run flutter upgrade.
To start the app on your smartphone via USB or inside an emulator just flutter run and have fun.
To build an Android or iOS App use flutter build apk or open the XCode workspace inside the ios folder to 'Archive' the app through XCode.
