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() => "FakeUsedError: '$_memberName'\n"
'No stub was found which matches the argument of this method call:\n'
'${parentInvocation.toPrettyString()}\n\n'
'A fake object was created for this call, in the hope that it '
"won't be ever accessed.\n"
"Here is the stack trace where '$_memberName' was called:\n\n"
'${createdStackTrace.toString()}\n\n'
"However, member '${_symbolToString(invocation.memberName)}' of the "
'created fake object was accessed.\n'
'Add a stub for '
"${receiver.runtimeType}.$_memberName using Mockito's 'when' API.\n";
