refactor-add-null-safety

To add null safety, you analyze code segments vulnerable to null reference issues and apply language-idiomatic solutions like optional chaining or nullable types to mitigate runtime crash risks.

Refactoring for null safety involves identifying vulnerable code segments and applying language-specific null safety patterns, such as safe calls and nullable types, to make legacy applications more robust.

Automated null safety analysis identifies code vulnerable to null reference issues and supports defensive programming by applying assertions and generating tests specifically for null cases.

You need to add null safety checks when your code may have null pointer issues, particularly before major releases, to ensure applications remain robust and stable against runtime errors.

Yes, you can apply null safety across various programming languages by implementing language-idiomatic solutions like optional chaining, nullable types, and defensive assertions tailored to each language's syntax.
