New post on /r/flutterdev subreddit: Prioritisation of notifications in flutter development. It seems to me that notifications are a prominent part of what makes mobile apps valuable, but flutter doesn't support this well.For instance, having to manually launch an app before notifications will work.It seem to me that Google has dropped the ball on this one.What's your view on this?

New post on /r/flutterdev subreddit: what do we need so that apple will approve our webview app? I have made a responsive website, and I want it to be an app, I don't want to do the whole process again, so I am using Flutter Webview.I have heard that Apple frequently rejects apps that are just webviews of websites, but the problem is the webview already has everything I might need, so, I don't know what "extra" feature to add so that apple will approve my app, got any suggestions?

New post on /r/flutterdev subreddit: When to start writting an App? Hi everyone!,Have you ever felt like you don't have enough knowledge build an App? Maybe felt like you are no educated enought to build the app of your dreams?Because of that feeling we postpone to first "learn" thoose glamorous tools and services. The problem is that maybe we expend way to much reading articles and articles instead of actually being productive.So my question is:¿When do you feel brave enough to start? ¿What strategy do you follow to avoid this feeiing? ¿What is the essential knowledge to build any app?Thanks for your attention.

New post on /r/flutterdev subreddit: Flutter Hooks Tutorial (Part 1): Flutter Animation using Hooks (useEffect and useAnimationController) Do you remember how we used to do programming before Flutter hooks weren’t part of Flutter? It was a bit difficult and overwhelming, right? Here’s a Flutter tutorial where we will explore pre-hooks and post-hooks Flutter life. We will learn how to use useEffect and useAnimationController in our demo app. Let’s get ready and build an application, then!Basics of Flutter AnimationIn this Flutter Hooks tutorial, we will learn how to install and build an animation demo using hooks in Flutter, and also, we will look at how we used to code before hooks weren’t introduced. Before moving on to the Flutter hooks tutorial, let’s discuss the basics of animation.We need to do the below things for animation,Animation controllerManage animationListen for updatesManipulate animationThe default part is the “Animation,” There are two types of animation that Flutter supports.Tween Animation– It is the short form of in-betweening. The animation must define the start and endpoint. The animation will have a start value and then reaches the end value through various intermediate values.Physics-based Animation– It allows you to interact with an app more realistically and interactively.In simple words, an Animation controller is called whenever its value changes, Ticker calls tick function every frame. After each tick, it provides a callback function after it is started. In our case, the ticker listener is the controller.Introduction: What is Flutter Hooks?Flutter hooks have not received much visibility and acknowledgment, but that won’t make them less awesome. With the help of the flutter_hooks library, we can provide a robust way for managing the lifecycle of widgets by reducing code duplication and increasing code-sharing.Flutter provides in-built hooks as shown below:useEffect hook fetches data from a server and sets the fetch to the local stateuseState hook manages local states in appsuseMemoized hook memoizes complicated functions to achieve optimal app performanceuseRef hook creates an object that has one mutable property.useCallback hook cache a function instance.useContext hook obtain the BuildContext of the building HookWidgetuseValueChanged Hook watches a value and calls a callback whenever the value changes.In this guide, we’ll use the useEffect hook for redirection after some duration, and useAnimationController hook to create an instance of AnimationController. Flutter, just like ReactJS, also gives you the opportunity of creating your custom hooks. We will discuss that later in the tutorial. Without further ado, let’s get started with the Flutter hooks tutorial.Read more for Pre-Hooks Life: Animation without Flutter Hooks.Note:This is an Original Content(OC).Spamming is like a deadly virus in your body and computer, so please don't do it.

New post on /r/flutterdev subreddit: Are there any disadvantages of using RepaintBoundary excessively RepaintBoundary is a widget that creates a separate display list for its child.I wrap all my animated widgets like marquee texts which animate forever with RepaintBoundary. This allows other sibling widgets to not get unnecessary rebuilds because of the marquee text widget and this seems to increase the FPS of the app.However I am skeptical on using RepaintBoundary all over the place. Do they have any side effects? Are there some cases which we need to be careful while using it?If they are only bringing performance improvements to the table and no side effects, why do animation packages in pub.dev do not publish the widgets already wrapped in RepaintBoundary widgets?You can see Remi's great explanation on RepaintBoundary. However he only talks about the use and advantages and not any side effects.The documentation does not give enough info on this widget.
