Flutter FloatingActionButton: A complete tutorial with examples

Flutter's FloatingActionButton (FAB) is a unique widget that adheres to Material Design guidelines, designed to float above other screen elements and typically located in the bottom-right corner. The FAB is primarily used for executing the main action on a screen, avoiding minor or destructive actions, and should be contextually relevant. Customization options for the FAB include altering colors, elevation, and positioning, as well as adding animations and transitions to enhance user interaction. The button supports the use of hero animations for seamless transitions between pages, allowing for a dynamic user experience. Extended FABs can include both icons and labels, providing additional flexibility. Flutter developers can adjust these properties to ensure the FAB aligns with the app's design and functionality requirements, creating an engaging and efficient user interface.
