Fake Firebase Remote Config

Fakes to write unit tests for Firebase Remote Config. Instantiate a FakeRemoteConfig, then pass it around your project to replace RemoteConfig.instance. This fake acts like RemoteConfig except it will load mocked data instead.

Usage

A simple usage example

import 'package:fake_firebase_remote_config/fake_firebase_remote_config.dart';

void main() async {
  final config = FakeRemoteConfig();
  await config.setDefaults({
    // ...
  });

  config.loadMockData({
    // ...
  });

  await config.fetchAndActivate();
}

This config object needs to replace the real RemoteConfig.instance during testing. You can do this for example with Riverpod or by doing something like this:

await tester.pumpWidget(
  MaterialApp(
    title: 'RemoteConfig Example',
    home: MyApp(overrideRemoteConfig: config),
  ),
);

Missing functionality

config.app will throw
config.pluginConstants will throw
config.getValue(String key) will throw if the key is missing
Everything related to config.settings serve no purpose. Data is loaded manually.
