This lesson discusses if and how to add dependencies, resolved by Angular ' s DI, to factory providers. The example used in this lesson builts upon the previous lesson on understanding factory providers.For example, the Loggerprovider need-to-use Consoleservice, as-you-put loggerprovider into ' providers ' array, we also Need to provide dependence which refer to Consoleservice, the "Do"providers: [ todoservice, consoleservice, , { = =
