Doc for file streams is incomplete

[carlos-verdes]

In the docs for FileStreams (to upload a file) we see the next example:

// Our client component calls the endpoint with `file.into()`
fn app() -> Element {
    rsx! {
        h3 { "Upload as FileUpload" }
        div {
            ondragover: move |evt| evt.prevent_default(),
            ondrop: move |evt| async move {
                evt.prevent_default();
                for file in files {
                    _ = upload_file_as_filestream(file.into()).await;
                }
            },
            "Drop files here"
        }
    }
}

// Our server endpoint accepts `FileStream`
#[post("/api/upload_as_file_stream")]
async fn upload_file_as_filestream(mut upload: FileStream) -> Result<()> {
    // ...
}

First the loop file in files is using an undeclared variable, in reality it has to come from evt.files().
Second the method .files() is available only if we import the proper trait use dioxus_html::HasFileData;.

Final code would be like this:

// import this to allow evt.files()
use dioxus_html::HasFileData;

// Our client component calls the endpoint with `file.into()`
fn app() -> Element {
    rsx! {
        h3 { "Upload as FileUpload" }
        div {
            ondragover: move |evt| evt.prevent_default(),
            ondrop: move |evt| async move {
                evt.prevent_default();
                for file in evt.files() {
                    _ = upload_file_as_filestream(file.into()).await;
                }
            },
            "Drop files here"
        }
    }
}
