Is it still useful that we're building the
ProgressBar
forDownloadingComponent
, rather than starting atDownloadContentLengthReceived
?There was a problem hiding this comment.

I believe this is justifiable since we don’t have access to the component’s name when creating a
DownloadContentLengthReceived
notification -- only the URL.With that in mind, and wishing to avoid parsing the URL to extract the component’s name, I think it’s best to keep the creation of the
ProgressBar
within theDownloadingComponent
notification.Additionally, I’d like to note that when retrying a download, the
DownloadingComponent
notification is not sent again. Moving the creation of theProgressBar
to theDownloadContentLengthReceived
notification could complicate the logic in theDownloadTracker
, particularly when handling download retries.There was a problem hiding this comment.

Moreover, I’d like to add that creating the
ProgressBar
withinDownloadingComponent
is the only way to ensure the output remains in the correct order when handling concurrent downloads.
