toString method
A string representation of this object.
Some classes have a default textual representation,
often paired with a static parse function (like int.parse).
These classes will provide the textual representation as
their string representation.
Other classes have no meaningful textual representation
that a program will care about.
Such classes will typically override toString to provide
useful information when inspecting the object,
mainly for debugging or logging.
Implementation
String toString() => '${get_type_name_of_the_toString(super.toString())}: (${this.in_types.toString().substring(1, this.in_types.toString().length - 1)}) -> (${this.out_types.toString().substring(1, this.out_types.toString().length - 1)})${isQuery ? ' query' : ''}${isOneWay ? ' oneway' : ''}, service: ${this.service}, method_name: ${this.method_name}.';
