higorlapa / result Goto Github PK

I think the title covers it pretty well but I will elaborate a bit further.

I am currently using version 3.1.0 of the package and was about to migrate to 4.0.0 when I realized, that the AsyncResult typedef along with its extensions was gone. I am heavily using this alias and its extension for a project of mine and just wanted to ask, why this feature was removed? Because in my opinion it does not conflict with the simplicity of the project.

I hope I did not come across as rude, I genuinely am just interested!

Hi,
How do we write test case for Result. I cant access the success or error value in test case. It always fail in
expectLater(response.tryGetSuccess(), true);

test('Give login request When login Then return success', () async {
    
    when(mockSettingRepository.addToBox<String>(accessTokenKey,loginResponse.accessToken))
      .thenAnswer((_) async => true);

    when(mockLoginRepository.login(loginRequest))
      .thenAnswer((_) async => loginResponse);

    final loginService = LoginService(mockLoginRepository, mockSettingRepository);
    final Result<bool, Failure> response = await loginService.login(loginRequest);

    
    expect(response.isSuccess(), true);
    expectLater(response.tryGetSuccess(), true);    
    expect(response, isA<Result>());    
    verify(mockLoginRepository.login(loginRequest)).called(1);


  });

If we are sure that there is no error we have to do something like this:

final userResult =
        await _apiAuthService.login(email: email, password: password);

if (userResult case Error(:final error)) {
  // handle error
}
final user = userResult.tryGetSuccess()!;

But I think that it would be better with something like this:

final userResult =
        await _apiAuthService.login(email: email, password: password);

if (userResult case Error(:final error)) {
  // handle error
}
final user = userResult.unwrap();

Any chance of flipping the types to improve the readability?

Currently, it reads like "result of an exception".

But when you flip the types to Result<Expected, Error> it becomes "result of something I expect".

Hello dev:

/// Return [Left] if the function throws an error.
/// Otherwise return [Right].
final tryCatch = Either.tryCatch(
  () => int.parse('invalid'),
  (e, s) => 'Error: $e',
);

Thanks.
