Project Features

See below for a list of project features. There is probably something that you, the developer, are looking for for your project and will take advantage of it from here. It is also possible that you already start your business with this application. We wish you all the best and much success!

Flutter: The T2Ti Pegasus POS is developed in Flutter and, therefore, it will be able to run on several platforms: Windows, Linux, MacOS, Android, iOS and for the Web. In this Beta phase we are doing tests on Windows and Android. With the launch of the project on github we know that we will have tests carried out by developers on other platforms. Soon, T2Ti will also start tests on other platforms. To compile the project use Flutter version 2.2.2.
SQLite: The Lite version of T2Ti Pegasus POS is single user and works with local database. The database chosen for this purpose was SQLite. The Premium version will work with SQLite as the local database, but will have the back-end database synchronization feature.

How it works – How to start it

You can clone the repository or download the zipped file, according to your preference.

Create a new project with the command ‘flutter create pegasus_pdv’. We created the application in the Beta channel because of Desktop support. You can use the Beta channel or the Dev channel. To change channels use the command ‘flutter channel beta’ and then the command ‘flutter upgrade’.

After creating the project, copy the ‘lib’ and ‘assets’ folders into your project. Also copy the files ‘sqlite3.dll’ to the root of the project, so that you can use the application on Windows. Copy the ‘env.example’ file to the project root and rename it to ‘.env’.

Finally copy the ‘pubspec.yaml’ file replacing the existing file. After copying this file run the ‘flutter pub get’ command to update the packages.

Ready! It’s all right to use the application. Open the project in VS Code or Android Studio and run or run the application with the following command ‘flutter run -d windows’.
