Create a new floating action button on the schedule view

The buttons of the app bar of the schedule view are not easy to reach on big phones. The solution would be making a floating action button with the following options : "return to today", "schedule settings" and "export". Ideally, we want animations, like in the link I added down below for reference, but in our case we should have text to the left of the icons that describe the actions. https://medium.com/@agungsurya/create-a-simple-animated-floatingactionbutton-in-flutter-2d24f37cfbcc
