Description: The ‘Null Safety’ is a programming practice used to ensure that a variable is not null before accessing it. In programming languages, where handling null references can lead to runtime errors, this technique becomes essential. The concept is based on the idea that variables should be validated before use, helping to prevent exceptions like ‘NullPointerException’. This practice not only improves code stability but also facilitates maintenance and understanding. Implementing null safety can include using conditionals to check if a variable is null, as well as utilizing tools and libraries that provide automatic verification mechanisms. In summary, null safety is a fundamental strategy in programming that aims to ensure the integrity of operations on variables, promoting more robust and less error-prone code.
