Dart Functions: Anonymous Functions or Lambda Expression

Lambda functions are a short and simple way to express tiny functions are also known as anonymous functions or closures.

They are functions without a name that can be used inline within the code.

return_type var_name = (parameters)=> expression;

Note, when using the Lambda function syntax, only one expression can be returned, and it must be a single-line expression.
