flutter_mockitory - Mock data layer with Flutter widgets #
The purpose of this package is to help test Flutter apps with fake data, but without changing the code.
With Mockitory you can mock data layer using the app itself by adding flutter_mockitory widgets.

How to use it? #
Add dependencies #

dependencies:
flutter_mockitory:

If you want to use pure Dart Mockitory (eg. for server apps), use mockitory instead of flutter_mockitory dependency.
Use Mockitory mixin #
import 'package:mockitory/mockitory.dart';

enum Gender { male, female }

class ExampleMockitory with Mockitory {
@override
Map<String, MockValue> get initialMockValues => {
'boolValue': MockValue<bool>(true),
'intValue': MockValue<int>(1),
'doubleValue': MockValue<double>(4.5),
'gender': MockValue<Gender>(Gender.male),
'listOfInts': MockValue<List<int>>([0, 1]),
'dateValue': MockValue(DateTime(2020, 5, 5)),
};

Stream<Gender> observeGender() => observeMockValueUpdates<Gender>('gender')
.map((mockValue) => mockValue.value);

DateTime getDateValue() => getValue<DateTime>('dateValue');
}

NOTE: Remember about using typed MockValue objects. Example: MockValue<bool>(true).
Use MockitoryPage widget #
MockitoryPage widget is used to automatically generate list of widgets used to update/display fake data.
final mockitory = ExampleMockitory();

...

MockitoryPage(
mockitory: mockitory,
customDelegates: [
CustomBoolMockValueDelegate(),
ChoicesMockValueDelegate<Gender>([Gender.male, Gender.female]),
IterableMockValueDelegate([
[0, 1],
[0, 2]
]),
],
),

Built-in MockValue Delegates #
Delegates are used to define how widgets used to manipulate fake data are built.
These delegates are used by default:

BoolMockValueDelegate
StringMockValueDelegate
IntMockValueDelegate
DoubleMockValueDelegate
DateTimeMockValueDelegate

These delegates needs to be added to customDelegates property in MockitoryPage widget:

ChoicesMockValueDelegate<T> - eg. ChoicesMockValueDelegate<Gender>([Gender.male, Gender.female])
IterableMockValueDelegate<T> - eg. IterableMockValueDelegate<int>([0, 1], [1, 4, 5])

Custom delegates #
You can provide your own custom delegate.
class CustomBoolMockValueDelegate extends MockValueDelegate<bool> {
@override
Widget buildMockValueWidget(BuildContext context, bool value, onChanged) {
return Checkbox(
activeColor: Colors.red,
value: value,
onChanged: (value) => onChanged(MockValue(value)),
);
}
}
