Purpose of Flutter Application
Hi all, I'm an entrepreneur making financial decisions around using Flutter. If you can write Dart directly in Atom, and control the CI/CD with Codemagic... what is the purpose of the Flutter application? Is it just more convenient? It seems like an IDE, but I read that you can just use Android

Architecting a flutter widget that contains different dynamic parts and animations
After learning about CustomPainter I built a widget like the one in the picture:https://i.stack.imgur.com/xDGsU.pngTo accomplish this I am just using a CustomPaint widget with a painter drawing the different arcs (canvas.drawArc).​Now, as you can see in the image, I need to bring a bit of life to the widget.First of all, I need to be able to rotate each ring of arcs independently from the others (for example the ring made with all the green arcs) and on the other hand I need to be able to change any arc color and width independetly.​The main problem I am facing, is that I need a some animations running at the same time (for example the 3 arc rigngs could be rotating at the same time) and I don't really know where should I place the animation controllers and the most important how to make the custom painter repaint when needed.​One aproach I have been thinking about is creating a widget called RingOfArcs and stack the 3 I need in a stack widget. This way, I could control the rotations, etc. with just surrounding each with a transform widget. But, I would like to create something more open. I mean, I would like to have a widget I could configure with a number of rings, pass the arcs that contains and angles and later be able to use something like: widget.rotateRing(0, 90º). And let the widget take care of everything.​Is there any way of doing this in flutter without having a mega spagetti of animcontrolers, widgets and canvas? And more important, for any param changing in a ring like an arc width/color etc. must I rebuild all the widget to force a repaint?

hi, I ran the row column example and noticed a few issues whilst running it in on my own IDE & flutter. I had to add main() and runApp() functions to run the code same. void main() { runApp(MaterialApp( title: 'row column Tutorial', home: MyWidget(), )); } that is not issue for me.

Action of "remove Widget" is gone in vs code.
when you press control + . (Dot/period) it shows actions to perform on widget(s). The "remove widget" was gone like a while ago but TIL that they changed the name to "replace with child" what do you people think of the new name did you know that?

Is Provider at the top level a singleton?
Hey all, I'm fairly new to Flutter and trying to figure out how to architect dependency injection and state management. I have been looking into how Provider works. I have seen people wrapping their entire app in a `MultiProvider`, then used Consumer/Selector to pull down the value. The docs seems to say that the provided class gets cleaned up when it is removed from the tree. But if it is supplied at the top level, it would seem that it would never get cleaned up.Is my reading correct? Is anyone using `Provider` for their DI?

Animation controlled by voice
Hello everyone,I recently joined the programming party with Flutter, and I decided to build a karaoke app, for fun!The code is coming along well, I am able to play songs, display lyrics on time, record a video of the performance and store it locally. The next step is to animate the pitch of the user's voice: I'd like to display an arrow moving up and down according to the voice input, but I have no idea how to animate things on Flutter. I had a quick look through the official docs but couldn't find anything. My guess would be using a game engine like Flame to do so, but I'm not sure if it is the best approach.Do you have any suggestion?Thank you! :)
