verifyDisposableTypeName function

Symbol verifyDisposableTypeName(
  1. Disposable object,
  2. {bool makeAssertion = true}
)

A helper to assert that the disposableTypeName getter has been, and remains, correctly overridden for a given Disposable subclass.

Example usage might be to call this from a test:

expect(
  verifyDisposableTypeName(myObject, makeAssertion: false),
  new Symbol('MyObject'),
);

By default, it will assert that the disposableTypeName matches the simple class name. It will also return the Symbol that represents the class name.

Implementation

Symbol verifyDisposableTypeName(Disposable object,
    {bool makeAssertion = true}) {
  final type = reflect(object).type.simpleName;
  if (makeAssertion == true) {
    assert(type == Symbol(object.disposableTypeName));
  }
  return type;
}
