* Move node implementation to Objective C This changes AccessibilityBridge::Node (C++) to be AccessibilityNode (objc) in order to have the nodes returned directly as ui accessibility elements. This buys us a few things: 1) We can now return an element tree instead of a flat list, thus negating the need to maintain a global rect and global translation 2) We use less memory since we don't need to instantiate both nodes and their ensuing accessibility elements 3) accessibility elements can now implement the methods necessary to respond to events like user scrolling https://github.com/flutter/flutter/issues/1664
Flutter Engine
Flutter is a new way to build high-performance, cross-platform mobile apps. Flutter is optimized for today's, and tomorrow's, mobile devices. We are focused on low-latency input and high frame rates on Android and iOS.
Flutter is an early-stage open-source project. We are still missing core features like accessibility, text input, localization, and more. However, you can build demos and examples today. We hope you try it out and send us feedback.
