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() {
final memberName = _symbolToString(_parentInvocation.memberName);
return '''Fake object created as a result of calling unstubbed member
$memberName of a mock.
Here is the stack trace where $memberName was called:
$_createdStackTrace
Normally you would never see this message, if it breaks your test,
consider adding a stub for ${_parent.runtimeType}.$memberName using Mockito's
'when' API.
Here is the stack trace where toString() was first called:
$_toStringFirstCalled
''';
