Simple closure in Dart

main.dart

// Closure example, sort of a companion to my JS example:
// https://repl.it/@MandiGrant/JSClosureExample

// combineNames is a function that returns a function.
var combineNames = (firstName) {
  return (lastName) => firstName + ' ' + lastName;
};

void main() {
  // Call it with a first name and then call *that* function with a last name
  var returnedFunction = combineNames('Anne');
  print(returnedFunction); // prints "{Closure 'main__closure'}"

  var fullName = returnedFunction('Jones');
  print(fullName);
}
