Flutter Test: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences)

Question

I am trying to test a function which makes an api call and save that data into shared preferences. I am mocking my api call but in that function when i am trying to get instance of shared preferences I am getting this error:

MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences)

This is my test case code.

main() {
 // setup
group("Login", () {
setUp(() {
  flutterTest.TestWidgetsFlutterBinding.ensureInitialized();
});
test("Valid Creds Login", () async {
  final validRes = ExpectedResponses.login();
  final client = MockClient((request) async {
    final res = json.encode(validRes);
    return Response(res, 200);
  });
  ApiController.init(client);

  final user = await ApiController.login(
      email: "abc@gmail.com", password: "12345678");
  expectAsync0(() {
    expect(user.id, "1763");
  });
}, skip: false);
});
}

Does this help? https://stackoverflow.com/questions/44357053/flutter-test-missingpluginexception/44360235 — Benjamin, Dec 23 '19 at 14:54
No. My issue is related to saving values in SharedPreferences. — Abdul Wahib, Dec 23 '19 at 15:24
Have you fully rebuilt your app since installing the SharedPreferences package? Which version of the package and of Flutter are you using? — João Soares, Dec 23 '19 at 15:42
I am running unit test for it, in actual application it is running fine. Shared Preferences: 0.5.6 | Flutter: 1.12.13+hotfix.6 — Abdul Wahib, Dec 23 '19 at 15:47

In my case this error solved by flutter clean command on terminal.

I think `flutter clean` is the first command, which developer tried – user7856586 Apr 08 '21 at 20:40

Below code is working perfect in my android project.

  class MainActivity : FlutterActivity() {

     override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {

             GeneratedPluginRegistrant.registerWith(flutterEngine)
      }
    }
