NoSuchMethodError constructor
NoSuchMethodError(Create a NoSuchMethodError corresponding to a failed method call.
The receiver
is the receiver of the method call. That is, the object on which the method was attempted called. If the receiver is null
, it is interpreted as a call to a top-level function of a library.
The memberName
is a Symbol representing the name of the called method or accessor. It should not be null
.
The positionalArguments
is a list of the positional arguments that the method was called with. If null
, it is considered equivalent to the empty list.
The namedArguments
is a map from Symbols to the values of named arguments that the method was called with.
The optional existingArgumentNames
is the expected parameters of a method with the same name on the receiver, if available. This is the signature of the method that would have been called if the parameters had matched.
