Unresolved reference: OkHttp in ktor-CodePudding

I am adding OkHttp in HttpClient. But I am getting error. Unresolved reference: OkHttp. I tried to add library in commonMain of build.gradle.kts, but I think I am missing some steps or doing something wrong. I want to use ktor Http but getting weird issue on my side. Can someone guide me, what am I am missing in my code?

import io.ktor.client.*
import io.ktor.client.engine.*
import io.ktor.client.engine.okhttp.*

fun createHttpClient() {
    val client = HttpClient(OkHttp)
}

build.gradle.kts

        framework {

        }
    }

        val commonTest by getting {

CodePudding user response：

Since OkHttp is designed to work on JVM and Android, you can't use it in the common code. You can create a different engine for each platform and inject it into the common code.

Or you can use expect-actual, see: https://ktor.io/docs/http-client-engines.html#mpp-config. You create an expect fun createHttpClient(): HttpClient in the common code, and actual fun createHttpClient(): HttpClient with the implementation for corresponding platform in each of the platform modules.
