Android 13 (SDK 33): PackageManager.getPackageInfo(String, int) deprecated. what is the alternative?

If you are using Kotlin, you can add extension function to your project:

fun PackageManager.getPackageInfoCompat(packageName: String, flags: Int = 0): PackageInfo =
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        getPackageInfo(packageName, PackageManager.PackageInfoFlags.of(flags.toLong()))
    } else {
        @Suppress("DEPRECATION") getPackageInfo(packageName, flags)
    }

and after just call packageManager.getPackageInfoCompat(packageName) or add another flag, if you need.
