A stateless widget is the primary building block for creating user interfaces. This widget is simple, lightweight, and performant. Flutter can render hundreds of stateless widgets without breaking sweat.
Stateless widgets are immutable. Once they are created and drawn, they cannot be modified. Flutter only has to concern itself with these widgets once. It doesn't have to maintain any complex life cycle states or worry about a block of code modifying them.
In fact, the only way to modify a stateless widget is by deleting it and creating a new one.
