Improve code safety and readability by efficiently dealing with null values in your Dart applications. Learn how to effectively handle null values in Dart using null-aware operators, including  null-aware access ( ?. ),  null-aware assignment ( ??= ),  null-aware cascade ( .. ), and  null-aware conditional ( ?? ).  .. Null-aware access operator (?.):  It is used to access properties or call methods on an object that may be null. If the object is null, the expression returns null without throwing an exception. class Person { String name; Person(this.name); void sayHello() { print('Hello, $name!'); } } void main() { Person? person; // Nullable Person object person?.sayHello(); // This will not throw an exception because of the null-aware access operator } .. Null-aware assignment operator (??=):   This operator assigns a value to a variable only if the variable is currently null. It is a handy way to set default values for nullable vari...
