What’s the difference between custom schemes and Universal Links in iOS Flutter?

Custom schemes (fitconnect://) are quick but show disambiguation sheets; Universal Links (https://fitconnect.app) are smoothly, domain-trusted, no prompts.

How do you handle initial deep links on Flutter iOS cold start?

In AppDelegate's didFinishLaunchingWithOptions, check launchOptions[.url] or userActivityDictionary for webpageURL, then set initialLink via MethodChannel.

Do Universal Links require server setup for Flutter apps?

Yes — apple-app-site-association file on your domain root, listing your app's team ID and bundle paths. Covered in Part 5.
