Flutter Null Safety with example - dart migrate - flutter tutorial

A Flutter Null Safety feature is a secured way of developing a flutter application, In any programming language, a variable can have a value assigned to it or might be null.

because in dart variable can be null & if a variable is null we cannot perform an action with it like, printing the null value on user screen or we cannot execute at string method to a null value & if we do so this may lead to null pointer exception & your flutter application will crash in run-time.
