AbSentry is an app built in Dart and Flutter intended to keep track of class attendance. It was originally built for a single teacher to use but I am busy updating it to allow user login and cloud storage for multi-device and multi-user usage. Even though it was meant for school attendance, it can be used for any group where attendance needs to be kept.
Absentry is still a work in progress. It is not usuable in it's current state. It does however take entries and saves this to a database, but there is no way to retrieve the data as of yet. THERE IS NO BACKEND CONNECTED TO IT. IT IS DESIGNED TO WORK WITH FIREBASE. You will have to add your own instance, THE CURRENT KEY IN THE CODE IS A DUD AND DOES NOT WORK. REPLACE IT WITH YOUR OWN.
