Replace <CURRENT_YEAR> with the actual current year (e.g., 2026).

// Copyright (c) <CURRENT_YEAR>, the Dart project authors.  Please see the AUTHORS file
// for details. All rights reserved. Use of this source code is governed by a
// BSD-style license that can be found in the LICENSE file.

• Ensure a blank line follows the license header before any other code or comments.
