[Help] SpriteWidget Tutorials/walkthroughs?
Hi all,I'm keen to jump on the Flutter bandwagon and have followed a few tutorials to get the basics down. While looking around, I discovered SpriteWidget, which could be used as a game engine.https://pub.dartlang.org/packages/spritewidget#-example-tab-I was attempting to create my own little game, using the space blast example here:Https://github.com/spritewidget/spaceblastBut I'm really struggling to get anything going. Ive googled, but there seems to be very little info out there on SpriteWidget beyond these few examples I've found. I was wondering if anyone knew of any resources that really walks you through what parts do, how best to layout code. I've tried to follow step by step how the space blast game works but am finding it very difficult. Any assistance would be greatly received. I wish I could write up some blog tutorials for this as I think it's really needed but have utterly failed.

App Launch Speed: Swift vs Kotlin vs Flutter
Hi, I'm investigating Flutter for native mobile app development. I created a trivial Flutter app. Launching the Flutter app on mobile device simulators was quick. Launching the Flutter app on physical devices felt laggy compared to much more complex apps I've written in Swift and Kotlin. This

What is the best solution for managing global state in Flutter?
So... I'm new to flutter and started a new application to learn the basics of dart and the framework. Having a React background I'm tending to use redux as the state manager. What is the industry pattern when it comes to state management? Is redux actually the best choice? Is there any native way to treat global state in flutter?

Does anybody knows why every time in a while Flutter gets me this error on "flutter run"?
Error connecting to the service protocol: HttpException: , uri = http://127.0.0.1:1025/ws Exited (sigterm)

Material Theme
Hi I find it confusing how the theme works in a material app. I know there is the *theme* property on *MaterialApp* constructor instantiating *ThemeData*. But then I'm lost. On *ThemeData* I have the property *colorScheme,* but when I assign some values to it, it is ignored by most (if not all)
