The primary function used to create a custom widget in Flutter is the 'build()' method. This method is required in every Flutter widget and is responsible for constructing the widget's UI by returning a widget tree. During the widget lifecycle, the 'build()' method is called whenever the widget needs to be rebuilt, allowing developers to define the appearance and behavior of their custom widgets dynamically.
