Part of https://github.com/flutter/flutter/issues/140804 Rather than using impeller::Command, the impeller::RenderPass records most state directly into the Vulkan command buffer. This should remove allocation/free overhead of the intermediary structures and make further improvements to the backend even easier. This completely removes the background worker threads used for encoding, which should lower overall CPU usage without decreasing performance by much (though it may be a tad slower or a tad faster).
Flutter Engine
Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. 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.
