Flutter Interview Questions ( Part 1 )
When was the stable version of Flutter released?
December 2019.
What are widgets?
Everything in Flutter is a widget, but what exactly is a widget? A widget is a user interface element.
What’s a difference between stateless and stateful widgets?
Stateless widgets have their state created only once — therefore, the build method is called only once as well.
Stateful widgets have their state explicitly created, and it can be modified during the lifetime of the widget.
