How do you check if an object is empty in darts?

A null indicates that a variable doesn’t point to any object and holds no value . You can use a basic ‘if’ statement to check a null in a piece of code. Null is commonly used to denote or verify the non-existence of something.

Null-aware operators in Dart help resolve this issue. They’re operators to say, “If this object or value is null , then forget about it: stop trying to execute this code.” The number-one rule of writing Dart code is to be concise but not pithy.
