Dart spread operator

27 August 2020 — Dart

Dart supports the spread operator, which allows to insert multiple elements into a collection.

return someVariable.toList()
    ..add(anotherObject)
    ..addAll(anotherListOfObjects);

becomes

return [
    ...someVariable.toList(),
    anotherObject,
    ...anotherListOfObjects
];

Even more concise and easier to read.
