Flutter Presentation Notes

Introduction to Flutter

• Open source portable UI toolkit
• Enables building for multiple platforms (mobile, web, desktop, embedded) with a single code base

Upcoming Features

• The focus of the event is to showcase sneak previews of different features under development.
• Four main categories:
  • Breakthrough Graphics Performance
  • Seamless Integration
  • Support for New Architectures
  • Developer Productivity Enhancements

Key Feature: Impeller

• Major rewrite of Flutter's graphics engine
• Smooth performance, especially in complex use cases like SVG clipping
• New architecture supports innovative use cases, including 3D capabilities.
