Unity Wallet Application - Firebase app creation failed

[software-programmer]

I wanted to have a look at the architecture of Bitflow to understand how you interact with the blockchain in order to change and track the state of something, but I'm having a an issue with the Unity wallet.

TBH, I've not used Unity before so might be something I'm missing.

I wanted to try and walk this through end to end. The web application appears to use WSS and this is working as expected AFAICT.

I'd really appreciate if you could spare 10 minutes to offer me some guidance.

It seems like firebase isn't being initialized. Bitflow uses firebase realtime database to communicate the state of what's going on on the blockchain - you can use some other method. From that printscreen it seems like your unity application is failing to initialize firebase. So you might want to look into firebase unity sdk docs to figure out how to use firebase realtime database with unity: https://firebase.google.com/docs/unity/setup If your target platform is webgl, firebases' unity sdk won't work and you'll need to integrate firebase in JS: https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html

OK. I assumed I'd be able to clone the repo and fire up the unity wallet without too many headaches

If you just want a unity walled you don't need Firebase.

I used NBitcon for the wallet, which is integrated under bitflow-unity/Assets/Libraries/
docs: https://github.com/MetacoSA/NBitcoin

UtxoUtils.cs helper class has a bunch of wrappers that help with the txn signing.
BitIndexUtils.cs queries BitIndex to figure out the state of txns - this differs from NBitcoin docs where they use QBitNinja

What happens when you open the project in unity and try to run the Main scene?
Make sure you switch the platform to Android under "File>Build Settings"
Do you see any compiler errors in the unity Console prior to running the scene?
I was using unity v2018.3.13f1 - but it should work on earlier versions
