How do you assess the importance of ensuring null safety in your code?

Ensuring safety from null values in Flutter code is critical for preventing runtime errors such as NullPointerException. Dart, the language of Flutter, supports null safety, which allows explicitly indicating which variables can be null and which cannot. This helps identify potential errors at compile time, increasing the reliability and stability of the application.

For example, if a variable is declared as String? name;, you need to check that it is not null before using it, or use the safe access operator ?. or the null-coalescing operator ??:

String? name;
print(name ?? 'Name not set');

Thus, proper handling of null values helps avoid crashes and improves code quality.
