Angular 1: $injector can't find a provider dependency when injecting provider inside a provider

To fix the issue you can do The order in which the services are defined doesn't matter during run phase, where service instances are injected. But it does matter during configuration phase, where service providers are injected, i.e. in provider constructors and config blocks.
Providers and config blocks are executed in the order in which they are defined. If Car provider is defined after ParameterService provider or config block, CarProvider doesn't exist at the moment when those two are executed.
code :
angular.module('app', ['app.carService', 'app.parameterService']).config(...);

angular.module('app.carService', []).provider('Car', ...);

angular.module('app.parameterService', []).provider('ParameterService', ...);

Flutter Provider: Why does this error happens when calling Provider.of<Widget>(context) like tihis:

hope this fix your issue The difference is that in the CustomText case, context is from its parent widget which is MyApp, whereas in the second case, context is from MyApp's parent. Since your Provider is implemented inside MyApp, it cannot find the provider if you use MyApp's parent's context (the second case)

it should still fix some issue You need to use the context to call Provider.of() so you can add addPostFrameCallback() which is called after the first build, there you can use the context
code :
void initState() {

    WidgetsBinding.instance.addPostFrameCallback((timeStamp) {
      auth = Provider.of<Auth>(context, listen: false);
