This is a non-breaking addition to the stable Flutter Embedder API and exposes a subset of the functionality provided by Dart_PostCObject API in a stable and tested manner to custom embedder implementations. Send port acquisition can currently be done as described in the unit-test but there may be opportunities to extend this API in the future to access ports more easily or create ports from the native side. The following capabilities of the the Dart_PostCObject API are explicitly NOT exposed: * Object arrays: This allows callers to create complex object graphs but only using the primitives specified in the native API. I could find no current use case for this and would have made the implementation a lot more complex. This is something we can add in the future if necessary however. * Capabilities and ports: Again no use cases and I honestly I didn’t understand how to use capabilities. If needed, these can be added at a later point by appending to the union. Fixes https://github.com/flutter/flutter/issues/46624 Fixes b/145982720
Flutter Engine
Flutter is Google's mobile app SDK for crafting high-quality native interfaces in record time. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
The Flutter Engine is a portable runtime for hosting Flutter applications. It implements Flutter's core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.
If you are new to Flutter, then you will find more general information on the Flutter project, including tutorials and samples, on our Web site at Flutter.dev. For specific information about Flutter's APIs, consider our API reference which can be found at the docs.flutter.dev.
Flutter is a fully open source project, and we welcome contributions. Information on how to get started can be found at our contributor guide.
