GGroup: Linear blending disabled - transparent elements (eg text) will be darker
TL;DR: The Flutter engine, as of http://ift.tt/2istO8z (November 14th) will render all transparent content in a way that's more consistent with other frameworks. This will almost certainly make your text higher contrast (and easier to

Reddit: Feasibility/practicality of reactive, immutable state
I've been developing applications in a few different frameworks and architectures but recenly I've fallen in love with React and Redux-style development. From my time with Angular, I got exposed to RxJS and in all of my modern apps I'm using it as a Redux "replacement" by essentially having the app re-render whenever my main data store, an Observable, receives an update. Knowing how React works, this is efficient because of React's declarative API that checks changes before touching the DOM and it is possible to write your app completely using nothing but stateless components.My question is basically, is it feasible right now to write an app in Dart with Flutter (and RxDart) with this architecture without performance concerns? I saw on the main Flutter documentation that some widgets provided by default are "stateful", as in they control and update their own state, which I would like to avoid as much as possible. It's not a dealbreaker as Flutter does look very nice but I've grown to appreciate pure functional composition in my apps and I'd like to continue using that style going forward. And if I do use pure, immutable widgets at all times, is there any React-style declarative mechanism to reduce the inefficiencies from that if any? Or am I misunderstanding how Flutter works?

GGroup: Flutter Engine port on WebGL / Canvas 2D
Hi, Thank you all for an amazing product. I would like to attempt a web-based Flutter Engine, seeing that dart:ui is the only dependency and that WebGL/Canvas2D seems to expose the required Skia / Text layer functionality. However I'm lost in the depth and width of the Flutter/Engine source

GGroup: Fragment-like behavior in Flutter
Hi, I'm making a Flutter app with a drawer. I would like the drawer to be the same for every route/page in the app, but every time i push a new page, the whole thing is being replaced, and I lose the drawer. Now, I could make it singleton, I could just be creative and build a different widget as
