WriteBlobWriteParams could not be found (even doe the js was loaded) about blazor.filesystem

Thanks for the very quick reply and your work on this Project! For my personal use it offers a little too many options. Thus, I might just use certain concepts and code pieces.

Regards and keep up the good work!

Hey @J4L0, you are right. When FileSystemWritableFileStream was changed to inherit from Blazor.Streams's WritableStream class instead of just Stream in version 2.0.0 of Blazor.FileSystemAccess I have accidentally also used the inherited helper JS file which originates from Blazor.Streams. But I have also gotten smarter since I wrote this originally a year ago and now have a way to parse the Blob argument from BlobWriteParams to the write method without a dedicated JS method. I will get that out very soon which should fix your immediate problems.

Apart from this I hear that you are looking into trying to write a DotNetStreamReference. To find examples where I have already done this I recommend that you check out Blazor.Streams and specifically take a look at Stream copying to a WritableStream and its associated source code WritableStreamCopyTo.razor which can be adjusted to writing to a FileSystemWritableFileStream from the Blazor.FileSystem library:

 // Some FileSystem stream you have gotten from a FileSystemFileHandle.
FileSystemWritableFileStream fsWritableStream;

// Some Stream of data.
Stream data = await HttpClient.GetStreamAsync("images/mountain.jpg");

// Stream copying.
await data.CopyToAsync(fsWritableStream);

Thanks for your interest in the library. 😁
