I need a small but critical change in my Flutter app’s admin dashboard. At the moment, admins paste a YouTube channel link into a plain text field; instead, that field must become a true YouTube search box. Here’s what the change should accomplish: • As soon as the admin starts typing, the box should call the YouTube Data API and auto-suggest matching channels. • Each suggestion has to show the channel’s name and thumbnail so it’s easy to recognise. • When a suggestion is clicked, the selected channel’s ID (or link, exactly as the current model expects) should be saved and behave just like the old manual-link flow. • If the query returns no results, the UI must display a clear “No channels found” message. Everything—including testing—has to be done live through TeamViewer; I cannot share the full source outside that session. The mobile side is already wired to pull the stored channel, so once the dashboard saves correctly, the job is done. The project is built with Flutter (Dart) and the dashboard uses the same codebase, so solid experience with Flutter web, REST calls, and the YouTube Data API is required. This is a quick fix for someone who knows their way around these tools.
