For embedder code that is configured for both AOT and JIT mode Dart execution based on the Flutter engine being linked to, this runtime check may be used to appropriately configure the `FlutterProjectArgs`. In JIT mode execution, the kernel snapshots must be present in the Flutter assets directory specified in the `FlutterProjectArgs`. For AOT execution, the fields `vm_snapshot_data`, `vm_snapshot_instructions`, `isolate_snapshot_data` and `isolate_snapshot_instructions` (along with their size fields) must be specified in `FlutterProjectArgs`.
Flutter Engine
Flutter is Google's mobile app SDK for crafting high-quality native interfaces on iOS and Android 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.
