Tag: What is Dart used for

In Dart, The var keyword is used to declare a variable . The Dart compiler automatically knows the type of data based on the assigned to the variable because Dart is an infer type language.

The Dart language now supports sound null safety! When you opt into null safety, types in your code are non-nullable by default, meaning that variables can’t contain null unless you say they can . With null safety, your runtime null-dereference errors turn into edit-time analysis errors.
