# noSuchMethod method

1. @pragma("vm:entry-point")

dynamic noSuchMethod (Invocation invocation)

Invoked when a non-existent method or property is accessed.

Classes can override `noSuchMethod` to provide custom behavior.

If a value is returned, it becomes the result of the original invocation.

The default behavior is to throw a `NoSuchMethodError`.

## Implementation

    @pragma("vm:entry-point")
    external dynamic noSuchMethod(Invocation invocation);
