● 가장 중요하게 생각하는것: 프로젝트의 전반적인 속도를 높이는것. ○ flaky tests와 같은 기술부채 감소 ○ 새로운 사람들이 팀에 합류하여 프로세스를 개선하는것 ○ 생산성을 보다 따르게 높이는것 1. Technical debt & team velocity 기술부채와 팀 속도
● Velocity 이슈들을 제기하거나 문서화하고 문제를 해결할 수 있는 팀원을 위한 정기 미팅을 시작(진행)할 예정 ● 정기 미팅은 Discord상에서 공지 예정 ○ https://discord.gg/BS8KZyg ○ https://github.com/flutter/flutter/wiki/Chat 1. Technical debt & team velocity 기술부채와 팀 속도
1. shader compiler jank를 완벽하게 제거하는것 ○ iOS부터 시작해서 Android와 데스크톱 플랫폼으로 확장 2. Web 성능 측면 ○ WebAssembly(wasm) 지원 3. Multi-threading rendering Flutter 성능 측면 2. Performance
1. Accessibility (접근성) ○ Flutter 애플리케이션에 쉽게 접근할 수 있도록 지속적 투자 예정 ○ 모든 플랫폼에서 접근성 지원의 품질 개선 2. Documentation (문서화) ○ 버그 수정, 소규모 패치의 형태로 이루어질 예정 품질 3. Quality 3. Platform ○ 빠르게 변화하는 Android, iOS에 대한 지원 ○ iOS: ■ Cupertino Widget + Widget 수 증가 ○ Android: ■ predictive back gesture ■ Android handwriting input ■ Camera플러그인 CameraX API 마이그레이션
SLSA 4. Security SLSA is a set of incrementally adoptable security guidelines, established by industry consensus. The standards set by SLSA are guiding principles for both software producers and consumers: producers can follow the guidelines to make their software more secure, and consumers can make decisions based on a software package’s security posture. SLSA’s four levels are designed to be incremental and actionable, and to protect against specific integrity attacks. SLSA 4 represents the ideal end state, and the lower levels represent milestones with corresponding integrity guarantees.
1. Popularity ○ 이슈의 👍(“thumbs-up”)수가 얼마나 있는지 확인 ○ 우선순위를 정하는데 도움 2. Parity and Portability ○ 1개의 플랫폼에서 기능을 지원한다면, 어느 플랫폼에서도 지원할 수 있는것이 중요 3. Supporting some other effort ○ 예) 성능 향상을 가능하게 하는 새로운 기능 Feature를 선정하는 3가지 동기부여 요소 5. Features
1. Custom asset transformers, because they enable some performance improvements. 2. Efficient 2D scrolling widgets (e.g. tables and trees), to improve the performance of applications with this kind of interface. 3. Multiple windows, especially for desktop platforms, because this is a very highly requested feature. 4. Platform Views on macOS and Windows, by popular demand. 5. Drag and drop, also by popular demand. 6. Wireless debugging on iOS, our second-most-requested feature. 7. Custom "flutter create" templates, which makes it much easier for third-parties (e.g. the Flame engine) to bootstrap developers. 8. Supporting element embedding (see also #32329), which allows Flutter content to be added to any standard web , by popular demand. 5. Features

5.3. Multiple windows, especially for desktop platforms, because this is a very highly requested feature.aq 5. Features https://docs.flutter.dev/release/breaking-changes/window-singleton The window singleton is deprecated In preparation for supporting multiple views and multiple windows, the window singleton has been deprecated. Code previously relying on the window singleton needs to look up the specific view it wants to operate on via the View.of API or interact with the PlatformDispatcher directly.
5.5. Drag and drop, also by popular demand. 5. Features https://github.com/flutter/flutter/issues/30719 https://github.com/flutter/flutter/issues/30719#issuecomment-901185947 2019~

Hot Reload on web 8. Non-goals https://github.com/flutter/flutter/issues/53041 ● 현재 이 이슈를 같이 작업할 Volunteered 가 없음. ● 장기적인 Web 관련 작업은 wasm에 초점을 맞추고 있기 때문 ● 곧 해결될 것으로 보이지 않음. ● 기술적으로 어렵고 미묘한 문제 2020
Built-in System - Automotive 8. Non-goals ● Apple CarPlay는 Oğuzhan Atalay가 만든 flutter_carplay를 추천 ○ CarPlay API 제어를 위한 Flutter API를 제공 ○ Apple의 API는 템플릿 베이스이다. (Apple's API is template based) ○ Flutter의 가치를 발휘하지 어려움. (렌더링 엔진, 위젯 프레임워크, 플랫폼 중립성 등) ● Android Auto의 경우도 동일 ● Oğuzhan Atalay와 함께 협업하여 작업하거나 새로운 플러그인을 만들기를 권장 ● CarPlay와 Android Auto가 직접적으로 화면에 픽셀을 그리는 방식을 https://github.com/flutter/flutter/issues/26801#issuecomment-1013565542

● State of the market ○ As of January 2023, there are over 700,000 apps in the Play Store that are built with Flutter, and one in five new apps on the Play Store use Flutter ○ Unlike traditional web frameworks, Flutter looks beyond the DOM and JavaScript to a new generation of Canvas and WebAssembly based APIs. Flutter in 2023: strategy and roadmap
We Must ● migrate our ecosystem to null safety without fragmentation ● continue to advance Dart tastefully and carefully ● eradicate jank and other performance impediments with minimal customer effort ● deliver unparalleled performance on all platforms ● reduce or eliminate friction when calling system APIs ● build in supply-chain security without impeding non-Google contributors ● build an ecosystem that is self-sustaining ● maintain and grow our reputation for quality ● win a reputation with design agencies and iOS developers ● close API and package divergences between platforms ● grow the diversity of our community ● support or integrate emerging ways of building UI, such as ML code completion and low-code tools.
we’ll shift our focus over 2023 away from stable releases as the primary vehicle for announcing new features and towards beta releases as the proving ground, as Chrome does.
