custom ByteArrayFetcher not working as expected

[mirjalal]

In v1.4.0 I have copied custom ByteArrayFetcher class from here. As the lib updated & some classes have been removed, I tried to rewrite & use it. Currently it looks like this:

class ByteArrayFetcher(
    private val data: ByteArray,
    private val options: Options
) : Fetcher {
    override suspend fun fetch(): FetchResult =
        SourceResult(
            source = ImageSource(
                source = ByteArrayInputStream(data).source().buffer(),
                context = options.context,
            ),
            mimeType = null,
            dataSource = DataSource.MEMORY
        )

    class Factory : Fetcher.Factory<ByteArray> {
        override fun create(data: ByteArray, options: Options, imageLoader: ImageLoader): Fetcher =
            ByteArrayFetcher(data, options)
    }
}

I added it to ImageLoader components like:

ImageLoader.Builder(context)
    .components {
        add(SvgDecoder.Factory())
        add(ByteArrayFetcher.Factory())
    }
    .build()

But it didn't help. Then tried to add it on each ImageRequest like:

ImageRequest.Builder(LocalContext.current)
    .data(dataModel)
    .fetcherFactory(ByteArrayFetcher.Factory())
    .transformations(*transformations)
    .build()

Still it cannot show the image.
p.s. in v1.4.0 there was no problem with the previous loader.

Did anybody faced & solved that (kind of) issue?

Hmm your Fetcher class does look correct. I'd check what error you're getting using listener(onError = {}).

Also Coil 2.0 adds support for ByteBuffers so you could also wrap the array using ByteBuffer.wrap(array) then you don't need the custom Fetcher.

thanks. ByteBuffer.wrap(array) solved my problem.
