* [fuchsia] enable boot time shader warmup even when LEGACY_FUCHSIA_EMBEDDER is defined * [fuchsia] decouple shader warmup from embedder api * [fuchsia] change warmup context flush() to flushAndSubmit() to reduce memory footprint of warmup * [fuchsia] Fix GPU resource lifecycle issue with shader warmup This fixes an issue with the shader warmup where gpu resources could end up deleted before the gpu work that needed them was complete, leading to GPU page faults. This was because although the sk_sp<SkSurface> will normally keep resources alive throughout its lifetime, the SurfaceProducerSurface will call VkDestroyMemory on the memory backing the SkSurface when it is deleted, even if the SkSurface wrapping that VkMemory is still alive. This change also deletes some related but unused code from CompositorContext that I noticed while refactoring.
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 want to run/contribute to Flutter Web engine, more tooling can be found at felt. This is a tool written to make web engine development experience easy.
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.
