Information if app is launched from CarPlay

[mefjuu]

I wonder is there a way to obtain an info (e.g. in initialTags) if app is launched from CarPlay?
It would be useful to tune initialization logic up, e.g. to reduce startup time or get rid of SafeArea blocking children rendering in CarPlay problem (AppAndFlow/react-native-safe-area-context#135)

When you set up your AppDelegate via initAppFromScene (see standalone-example) or similar you can simply pass arguments or flags to initAppFromScene from your CarScene and store them in the initialProps, which you can then access in react native.

@DanielKuhn I've just noticed it can be distinguished by concurrentRoot !== false initial prop when running on RN 0.74.x

 LOG  Running "MyApp" with {"rootTag":61,"initialProps":{"concurrentRoot":false}}
 LOG  Running "MyApp" with {"rootTag":71,"initialProps":{}}

while in repo's example app (not upgraded to the latest RN) initialProps are exactly the same

 LOG  Running "RNCarPlayScene" with {"rootTag":1,"initialProps":{}}
 LOG  Running "RNCarPlayScene" with {"rootTag":11,"initialProps":{}}

If that's good enough for you, fine.
Just saying, though: If you need to be able to start your CarPlay app without the phone app running, you'll need to migrate to initAppFromScene sooner or later anyways

Ok, I've checked the linked PR. However, there any reason it hasn't been merged yet?
I'd like to use an "official" way of doing it though :)

I guess you'll need to get used to the fact that there's no "official" way to integrate CarPlay into a react native app. The way an app is started natively from CarPlay results in native implementations of Scene and AppDelegates which always need to be adjusted to the react native version you're using in your app.
React Native will not support SceneDelegates (or Swift) any time soon: facebook/react-native#41777
