Hello, I am trying to create a multiplatform image loading library, I use ktor for remote loading and okio for local loading(files).
I want to have an interface for fetcher that returns a flow of Loading(progress), Success(something), Error(throwable)

I am not sure what something should be to support both fetchers.

For remote loading I was thinking about using ByteReadChannel like in this library:

And the file fetcher looks like this:
https://github.com/alialbaali/Kamel/blob/main/kamel-core/src/jvmMain/kotlin/io/kamel/core/fetcher/JvmFileFetcher.kt

I want to use `okio`'s Path to load from files and support multiplatform, but I don't know how to create a ByteReadChannel, I tried creating an extension for it based on File.readChannel, but some of the methods are internal and I gave up in the end.

You can create a channel from a java.io.File :

File("/path").readChannel()

or use a writer to write data to a channel:

val readChannel = GlobalScope.writer {
    // channel.writeFully()
    // channel.writeStringUtf8()
}.channel

It works for jvm, but not for other platforms, I tried making a new method based on that and change it to support ByteReadChannel but no luck

With a writer you can write data from any source.
