[FR] Able to drop analytics events before CheckAndFixDependenciesAsync() completes

[AntonPetrov83]

The official guide recommends to set a flag when CheckAndFixDependenciesAsync completes to indicate that Firebase is ready.

Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {
  var dependencyStatus = task.Result;
  if (dependencyStatus == Firebase.DependencyStatus.Available) {
    // Create and hold a reference to your FirebaseApp,
    // where app is a Firebase.FirebaseApp property of your application class.
       app = Firebase.FirebaseApp.DefaultInstance;

    // Set a flag here to indicate whether Firebase is ready to use by your app.
  } else {
    UnityEngine.Debug.LogError(System.String.Format(
      "Could not resolve all Firebase dependencies: {0}", dependencyStatus));
    // Firebase Unity SDK is not safe to use here.
  }
});

Otherwise, an exception gets thrown:

InvalidOperationException: Don't call Firebase functions before CheckDependencies has finished

So how am I supposed to log early events? What are the best practices?

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @AntonPetrov83, any events happens before Firebase Initialization can't be logged properly by firebase. That should be one of the earliest init of the app. I'd like to get more context of what you might want to log earlier.

Hi @cynthiajoan , I would like to log very early events like "loading_start" to build funnels later.
In my app there is an umbrella class used to log events to different systems through a single API.

The problem with Firebase SDK is that it requires async initialization so this only SDK blocks the entire logging system from early start. As a workaround I implemented a queue to collect calls into Firebase until it is initialized. And this is ugly.

I think such design shifts a lot of complexity from the Firebase SDK to the client side. Events logging must work through a simple static API and managing initialization and connection issues must be hidden on your side.

With all my respect to your hard work.

Hi @AntonPetrov83

Unfortunately this is how the API is designed now. CheckAndFixDependenciesAsync() is primarily used for Android build to make sure all required deps, primarily Google Play Services, is installed and met minimum versions for all Firebase components used in your app.

I understand your concern. This seems to be a feature request for a design change (quite major one actually). Please allow me to change the label and title a bit.

@AntonPetrov83 you inspired me to write this short article ;)
