Hello! Is there a way to provide 3d party context to Composable Preview? Details in the thread.

@Composable
fun DGisMapComposable(dGisContext: Context) { .. }

@Preview
@Composable
fun DGisMapComposablePreview() {
    // provide dGisContext somehow
}

Never heard of dGisContext before, Google also shows 0 results. What is it and how does it differ from the regular “context: Context”?

[Anastasia Rozovskaya]

it’s just a context needed for using a map api https://docs.2gis.com/en/android/sdk/overview
(like Google Maps)

[Zun]

LocalContext.current?

[Anastasia Rozovskaya]

Yeah, I tried that, it doesn’t work in my case

[Zun]

What doesn't work

[Anastasia Rozovskaya]

when I put LocalContext.current in place of dGisContext inside preview I’m getting an error

[Zun]

What error

[Anastasia Rozovskaya]

If you are not making fun of me right now, the error is obviously in a type mismatch. Required: ru.dgis.sdk.Context, but found android.content.Context

[Anastasia Rozovskaya]

dGisContext is an intrinsic context of this 3d party maps library, which is a wrapper of applicationContext with some additional properties

[Zun]

It isn't so obvious because this is a Russian library that might not be so popular for most developers.

Anyway

val androidContext = LocalContext.current
val sdkContext = DGis.initialize(
androidContext, ApiKeys(
directory = "Directory API key",
map = "SDK key"
)
)

[Zun]

You should probably create a factory method to retrieve that DGis context somewhere to prevent duplicate code

[Anastasia Rozovskaya]

Ok, thank you. I’ll give it a try

[Anastasia Rozovskaya]

Well, just to be clear. I had initialised context the way Zun proposed. And I use Hilt to inject it in my fragment, where I call the map compose function. The original question was about any 3d party context in compose preview. If anyone had a case like that, please, ping this thread. Thanks
