# Invocation.setter constructor Null safety

Invocation.setter(

1. Symbol memberName,
2. Object? argument

)

Creates an invocation corresponding to a setter invocation.

This constructor accepts any Symbol as `memberName`, but remember that actual setter names end in `=`, so the invocation corresponding to `object.member = value` is

    Invocation.setter(const Symbol("member="), value)

## Implementation

    factory Invocation.setter(Symbol memberName, Object? argument) =
        _Invocation.setter;
