Hi guys!
I want to implement text share functionality in KMP, how it be done as Android involves context and I'm using Koin for DI..?

You can create an interface in commonMain kotlin and implement it in iOS-Swift and Android side.

[Pablichjenkov]

Something like

Interface StringResolver{
   fun getStringById(stringId: Int) : String
}

Then provide to koin each implementation the swift one and the Android one.

I have done this, now struggling after this.
Usage with Koin

What fails more specifically?

[Ahmad Hassan]

class TextSharing_iOS: TextSharing {
    override fun shareText(text: String) {
        val activityItems = listOf(text)
        val activityViewController = UIActivityViewController(activityItems, null)

        val application = UIApplication.sharedApplication
        application.keyWindow?.rootViewController?.presentViewController(
            activityViewController,
            animated = true,
            completion = null
        )
    }
}

class AndroidTextSharing(private val context: Context): TextSharing {
    override fun shareText(text: String) {
        val shareIntent = Intent().apply {
            action = Intent.ACTION_SEND
            putExtra(Intent.EXTRA_TEXT, text)
            type = "text/plain"
        }
        context.startActivity(
            Intent.createChooser(shareIntent, context.getString(
                R.string.app_name)))
    }
}

Now how to use in commonMain?

[Pablichjenkov]

It seems that TextSharing_iOS is not in Swift
Better doing it in swift

I want to use it in Compose Multiplatform
