server.start();

cli: Karma is more strict and will error out if unknown option or argument is passed to CLI.
Using Karma to run Dart code in the browser is no longer supported. Use your favorite Dart-to-JS compiler instead.

dart file type has been removed without a replacement.

customFileHandlers DI token has been removed. Use middleware to achieve similar functionality.
