# flutter embedding add-on

For the better experience when adding [Flutter to the existing APP](https://flutter.dev/docs/development/add-to-app), we will pre-warmed the `FlutterEngine` when the APP starts, and then use it later. This does make the better experience when launching the Flutter page, but if the Flutter page has not been opened after the APP is started, the cached `FlutterEngine` will always exist in memory, which causing the memory of `FlutterEngine` to be wasted. Because the memory of the cached `FlutterEngine` cannot be released, in the worst case, it will cause OOM when the memory is insufficient. We can solve this problem by creating the `FlutterEngine` lazily. The `FlutterEngine` is created and cached when the user first enters the Flutter page, and the cached `FlutterEngine` can be reused when the user enters the Flutter page again.

This project show you how to lazily creates and manages `FlutterEngine` on Android and iOS. In this way, we can better solve the problem of page navigation like `Flutter -> Native -> Flutter`, and the project sample shows such a scenario.
