SafeCallExtension extension

Extension on CLBaseViewModel that wraps a network call with the standard busy/error pattern used across the app.

  • Toggles setBusy(true/false) around the call.
  • Returns the value produced by onSuccess when the response succeeded (HTTP 2xx), otherwise null.
  • On non-2xx or thrown exceptions, optionally shows a danger alert via AlertManager.showDanger.

Usage:

final user = await safeCall<UserModel>(
  call: () => ApiManager.instance.makeApiCall(...),
  onSuccess: (data) => UserModel.fromJson(data),
  errorTitle: 'Errore',
  errorMessage: 'Impossibile caricare utente',
);
on

Methods

safeCall<R>({required Future<ApiCallResponse> call(), R onSuccess(dynamic data)?, String errorTitle = 'Errore', String? errorMessage, bool showErrorAlert = true, bool manageBusy = true}) → Future<R?>
