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
@override
String toString() {
switch (_state) {
case _SnapshotState.unresolved:
return 'ZapSnapshot (unresolved)';
case _SnapshotState.data:
return 'ZapSnapshot (data = $data)';
case _SnapshotState.error:
return 'ZapSnapshot (error = $error)';
}
}
