Expected API call

expected_api_call.dart

//Instantiate a service and keep it in your DI container:
final service = NetworkService(baseUrl: 'https://www.domain.com/api');
// Prepare a request:
final request = NetworkRequest(
  type: NetworkRequestType.POST, 
  path: '/authenticate',
  data: NetworkRequestBody.json({
    'login': 'user_name', 
    'password': 'password'
  }),
);
// Execute a request and convert response to your model:
final response = await service.execute(
  request, 
  AccessTokenResponse.fromJson, // <- Function to convert API response to your model
);
// Handle possible outcomes:
response.maybeWhen(
  ok: (authResponse) {
    // Save access token or proceed with other parts of your app
  },
  badRequest: (info) {
    // Handle specific error
  },
  orElse: () {
    // Handle generic error
  }
);
