Convert User Input String To Int - Learn Dart Programming 11
Показать описание
In this video we'll learn how to take user input and convert it's type from a String to an Int with Dart.
Whenever we get user input, dart takes that input as a string by default.
But to convert it to an Int, we need to deal with nullability using the ?? operator.
I'll show you how to do that in this video.
