Tag: How do you define a function in darts?

Defining Variables One of many ways, and the simplest way, to define a variable in Dart is using the var key word . var message = ‘Hello, World’; This example creates a variable called message , and also initializes the variable with a String value of Hello, World .

Either declare the function as static in your class or move it outside the class altogether. If the field isn’t final (which for best practice, it should be, unless the field has to mutate), you can initialize it using a regular non-static method in the constructor body .
