-Flutter's engine takes core technologies, Skia, a 2D graphics rendering library, and Dart, a VM for a garbage-collected object-oriented language, and hosts them in a shell. Different platforms have different shells, for example we have shells for [Android](https://github.com/flutter/engine/tree/main/shell/platform/android) and [iOS](https://github.com/flutter/engine/tree/main/shell/platform/darwin). We also have an [embedder API](https://github.com/flutter/engine/tree/main/shell/platform/embedder) which allows Flutter's engine to be used as a library (see [[Custom Flutter Engine Embedders]]).

-While we do not object to teams creating custom builds of the Flutter engine for their purposes, we do not support this configuration. Not supporting it means that we do not commit to any timelines for fixing bugs that may come up in such a configuration, even for customers for which we would usually be willing to make commitments (see the [[Issue Hygiene]] page). It also means that we encourage teams to view such configurations as short-term solutions only and encourage teams to transition away from such configurations at the earliest possible opportunity.

 We do not expect custom engine builds to be long-term sustainable. They are not supported on any platform where we plan to be the publisher of a Flutter runtime distinct from the applications that run on the runtime, and they require significant effort to port to our new target platforms such as Web and desktop. There is also an expensive maintenance burden (for example, if we add new features, a custom engine build would need to be updated to support that feature).
