ARTICLES
Binary Tree<T> implementation using Dart
Suman Manna has described binary trees as a fundamental data structure in computer science, often used for searching and sorting algorithms. They are tree-like structures with each node having up to two children referred to as the left and right children. Binary trees allow for fast searching, insertion, and deletion due to their logarithmic height. Manna has also provided an implementation of a Node class in Dart.
GestureDetector class on Flutter
According to Siddhant Vijay Singh, GestureDetector is a Widget that can detect user gestures on screen in order to create a more interactive user experience. It can be used for things like swiping in the direction of food in a snake game. The GestureDetector widget can detect gestures such as taps, double taps, and long presses, and its properties allow developers to specify callbacks for each gesture.
Equatable package in dart
Shan Shaji explains how to use the Equatable package in Flutter to compare objects and create custom value types. He provides an example of how to extend the Equatable class and implement the props getter, as well as how to use the == operator or isEquals() method to compare two instances of the same type.
How to use get_it package
get_it package is a service locator for Dart and Flutter applications that allows users to register and retrieve objects. It can be used to create singletons, factory functions, non-singleton objects, and more. The package documentation provides further information on its advanced usage.
Why we should not use any third-party state management tool in Flutter
Muhammad Ali's article discusses the importance of using state management tools in Flutter projects, and advises readers to research the author or company behind any package before using it.
Architecting Network Layer in a flutter application (Scalability)
Harsh Vardhan Gautam has presented a solution to managing network layers while developing an application with Flutter to improve scalability. He proposes the first principle of talking about the problem and then finding a solution that is best suited for it. He then goes on to explain how to create a scalable architecture for the network layer.
Flutter go_router: The Essential Guide
go_router package is a useful third-party solution for routing in Flutter, allowing users to have more control over how routes are defined and managed in their app. It can also handle web support and deep links. To get started, users need to add go_router to the pubspec.yaml file and define the GoRouter configuration object in their application. Additionally, path parameters can be specified by prefixing a path segment with a : character followed by a unique name.

Flutter App Crashing with OOM - details in stack overflow
Hey Flutter community! Could anyone have a look at this issue - I'm stuck! Flutter app has been working for months and now is suddenly plagued by out of memory crashes. Any help appreciated 😁I will post the error below the link to the stack overflow question (which has lots of detail).
New to flutter and dart, how do your run a python script and return a value from it into dart?
I made a python script that reads a file and prints a value, and I want to use that in dart, is this possible? I've heard you can use flask for that but I don't know how.

Is there anything wrong with passing a function as a parameter?
I've recently discovered that Dart apparently doesn't allow for passing variables by reference. This isn't a huge problem because I don't often need to do it, and I've found a simple enough solution which is that whenever I'm in a situation where I'm creating functions that would benefit from being able to take a variable by reference, I instead make the parameters functions that either get or set my variable. Its a little clunky but it does work on the few occasions where I need to do it.My question is, is there anything wrong with doing this? I've been reading a few different forum and blog posts that talk about the lack of pass by reference, and mostly the solution seems to be making a wrapper of some kind. But I've not seen anyone mention using getter/setter functions as parameters as a valid (while yes a little ugly) solution. Am I missing some big flaw with my solution?
r/FlutterDev
Should I use native or flutter for this project?
So I'm making an app which requires the users camera to switch on and detect their pose (AI based pose detection). The goal is to count the number of seconds they do a particular yoga pose. Is this possible using flutter or should I stick to native app development for this project?
Animate Stack Children on reposition.
So I am trying to create a carousel slider in which I have 3 cards . So one in the middle is at front(top of the stack). I want slide left nd right to cycle through cards. But while cycling through them I also want to animate them.Let's say while Card A is at the front and Card B is to right and behind Card A . And Card C is to right and behind Card A. If I swipe left Card B should be animated while coming to front.What are possible ways to do this ?Note :- Behind Cards are overlapped with front card. Meaning some part of behind cards is visible and rest is behind the front card.
