Good question. It seems very cumbersome to read long text in this half-screen-scrolling UI. I am assuming that most people will paste the text from somewhere else, in which case the specifics of the original text doesn't matter much. We can just keep the header bar sticky and scroll the rest like usual.

Other than that, 2 small points:

• "Source language" seems a bit technical, we can change that to "Translate from"
• It is not obvious from the UI that there is a dropdown for the languages, so we should add a small chevron-down icon next to the language.
• There's also a floating button and I am not sure what it does (is it a button to force translation or create a "new translation task"?). would it be possible to just automatically translate whenever the source text changes (maybe throttled to 500ms or something to avoid sending too many requests)?

blue-Light-Screenshot test failed, but no output was generated. Maybe a preliminary stage failed.

Looks good :)

One point of feedback though:

Once the translation started, it would be good to display a different message on the bottom, just something like "Translating…" instead of showing a toast.

The existing message could then be adjusted to say "Press the translate button to begin" instead of "Your translation will appear here…" to indicate that translation is not instant, unlike in many other apps.
