# noSuchMethod method Null safety

dynamic noSuchMethod (

1. 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);
