For consistency with Android, when the engine receives a TextInput.setEditingState message from the framework, and the text has changed, we now send a TextInputClient.updateEditingState message back to the framework with the updated state from the engine. The framework currently relies on this behaviour to trigger onChanged events in certain scenarios (e.g., on tapping Paste in the selection controls). Note: it may be more desirable for the framework to trigger the onChanged calls without relying on the return message from the engine, but this change ensures consistent behaviour across iOS and Android until we've evaluated the pros/cons of such an approach.
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.
The Flutter Engine is the runtime environment for hosting Flutter applications. Most developers will interact with Flutter via the Flutter Framework and APIs, which run inside the engine.
Flutter is an early-stage open-source project. We are still adding features. However, you can build demos and examples today. We hope you try it out and send us feedback.
