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() =>
"MissingStubError: '${_symbolToString(invocation.memberName)}'\n"
'No stub was found which matches the arguments of this method call:\n'
'${invocation.toPrettyString()}\n\n'
"Add a stub for this method using Mockito's 'when' API, or generate the "
'${receiver.runtimeType} mock with the @GenerateNiceMocks annotation '
'(see '
'https://pub-web.flutter-io.cn/documentation/mockito/latest/annotations/MockSpec-class.html).';
