# Invocation class abstract

Representation of the invocation of a member on an object.

This is the type of objects passed to Object.noSuchMethod when an object doesn't support the member invocation that was attempted on it.

## Constructors

Invocation()
Invocation.genericMethod(Symbol memberName, Iterable<Type>? typeArguments, Iterable<Object?>? positionalArguments, [Map<Symbol, Object?>? namedArguments])
  Creates an invocation corresponding to a generic method invocation.
  factory
Invocation.getter(Symbol name)
  Creates an invocation corresponding to a getter invocation.
  factory
Invocation.method(Symbol memberName, Iterable<Object?>? positionalArguments, [Map<Symbol, Object?>? namedArguments])
  Creates an invocation corresponding to a method invocation.
  factory
Invocation.setter(Symbol memberName, Object? argument)
  Creates an invocation corresponding to a setter invocation.
