Understanding Memory Usage
Im wondering if anyone out there can help me better understand the memory tab for Dev Tools.I have a widget with 3 buttons, each is an option ie. Ok, Defective, N/A. When the widget first loads and i take a snapshot i get 1 count of each widget in the instance. However as i a switch between options ie, tap ok, then tap defective etc and take another snapshot, the count in the heap goes up and up. Even more so the other widgets that share the screen with these ok, defective, n/a options also increase their counts in the heap.Any help here would be greatly appreciated.

You always wanted to automate the verification of your project dart code style ? aka (analysis_options.yaml) But could not find a free tool for that ? Or you wanted to verify that a pull request meet your coding style guide? dbstyleguidechecker package is here to help.

Dart has extensions! It's 2.6 dev branch iirc but the analyzer is setup to play around with it already.

How to add stickers in app?
Hello Fellow flutter developer, I need some help from you. I am building a social app and I want to add sticker to it. I want the stickers to pop up when you click on an icon like the keyboard pop ups and when i click on the icon again the keyboard should pop up. How would you go about implementing it? I cannot find any guide online on how to do this.
Sorry for my bad english as i am not a native english speaker.

Flutter compared to other cross-platform frameworks
React Native/NativeScript/Xamarin: Hey lets use platform widgets to render our views! Wrap that stuff up nicely and we're good to go!Flutter: Oh, you think the cross-platform is your ally, you merely adopted cross-platform. I was born in it, molded by it. I didn’t see the high-performance until I was already compiled; by then, it was nothing to me but skia-renderings! Cross-platform betrays you, because they belong to me. I will show you where I have rendered my own widgets through skia, while preparing to bring high-performance. Then, I will break you. Your precious adoption rate, gratefully accepted. We will need it. Ah yes, I was wondering what would break first. Your platform-interfaces, or your developers?

Is Flutter ready for AR application development?
Hii, I'm working on an Augmented Reality project and is interested in Flutter due to the performance gain and development ease. But the only AR plugin I found was still in it's development stage. So, is there anything I missed? Is there any official plugins for AR Core. Thanks

I've just published a project times tracker app on Play Store
Hello everyone!My name is Giorgio and the past weeks I posted here 2 speed code videos I uploaded on YouTube.Now I decided to publish that app on the play store, it's a times tracker app, personally I'm using it to track the time I invest in my personal projects and in study, so I can better manage my time.I used Hive for storing data locally, if you don't already know what Hive is, I suggest you to check it out, it is a very very fast key-value database written in Dart.I hope it'll be useful for you too.

Rumors about Maps in Flutter Apps
Hi! I am a mobile developer.I have heard rumors that Flutter doesn't have fluid maps because of the fact that it manipulates pixels on the screen.
Is it true that the map experience is still not great?The last time I used an app built by Flutter, it was really smooth, and felt like the future.
Thanks

CS basics: Why can phones easily run graphically intensive games, but then have problems with scrolling a ListView at 60fps?
Good day.Over the last few days I read a few articles/blog posts about how Flutter draws widgets to the screen and how there were/(still are?) performance issues when for example scrolling a list. I am only a hobbyist, so I'm lacking a CS background. I really do not understand this:Phones can easily run graphically intensive games with tens/hundreds of thousand polygons, textures, shaders, real-time shadows, particle effects, etc, but then that same phone has problems drawing a simple ListView containing only text and maybe a little icon at 60fps? I must have a massive misunderstanding about how GPUs work or how graphically intense a few simple text fields are.In my mind/logic I would assume that displaying something like the Facebook/Spotify/Whatsapp app would require magnitudes lower GPU load than running a 3D game. However clearly that's not the case. So what am I not understanding here? Does a simple scroll-view really max out my phones GPU (as much as a 3D game would)? Sounds almost unbelievable.Thanks so much in advance

Proposal for extending the Navigator and adding a Router widget

I used Firebase with Flutter for starting and its amazing...but.....
Why arent all apps using whatever method Firebase has for real-time data? The whole pull to refresh idea now seems super super super ghetto......

Dart PSA: You can try the dart2native tool (part of the Dart SDK, but not yet in stable) to compile your Dart tools and programs to standalone executables.
