Embedding a Flutter web app into a part of your page is totally possible, but it’s not just copy-pasting the snippet from the docs. Flutter lets you attach your app to a custom element, which is perfect if you don’t want it taking over the whole page. The official docs show how to do it (https://docs.flutter.dev/platform-integration/web/embedding-flutter-web#custom-element-hostelement), but in practice, there’s more to it than just adding the code. If your HTML page and the Flutter build are in different folders, things get tricky. Flutter needs several files to run properly: the bootstrap script, the compiled Dart code, the service worker, and the assets. If the paths don’t line up with your page, the app won’t load, and you’ll end up chasing missing files. So you need to adjust how Flutter finds those resources. You need to make sure the bootstrap script knows where to find the compiled Dart code and the service worker, ensure the assets folder is reachable from your page’s location, and double-check everything works together before going live. Once these are sorted, you can drop your Flutter app into any section of your page, and it’ll work smoothly.
