In Flutter, you can make two kinds of widgets - Stateless and Stateful. So what the Flutter are widgets, and what's their lifecycle? In fact, everything in Flutter is a widget, including your entire Flutter app itself, and if you look at Flutter's source code, many widgets are themselves made of widgets behind the scenes. If you are coming from the world of Jetpack Compose, think of Widgets as Composables. Overall, in my experience, Hot Reload has been very useful and there were only a few scenarios where Hot Restarts were required. Why? The reason probably is: Any changes that are outside of the build method will require a Hot RestartĪnd not just the build method - if you change anything in initState() or dispose() or value of a static variable since these changes aren't called by build method, the changes won't be picked up by hot reload. So you try reloading the app but when you change your root class nothing happens. Wanna change layouts, colors, or widget sizes? Hot reload lets you do that without restating your entire app. One of the amazing abilities Dart provides to flutter is Hot Reload – the ability to see most of the changes in the app source live, without restarting it. On top of all this, Dart is null-safe and has a very popular and open-source package manager called pub, which can be found at pub.dev. Dart is a type-safe programming language just like Typescript or Kotlin, and also provides dynamic types and runtime checks when needed. It also has a JIT or (just-in-time) compiler which speeds the language up and improves developer productivity by adding features like Hot Reload and Hot Restart. Why Dart?ĭart is a client-optimized general-purpose programming language, designed to build fast and beautiful apps across multiple platforms such as arm64, x86_64, and even Javascript for the web, developed by Google and launched in the year 2011. If you get an error saying Android Studio can't be found, add it manually: flutter config -android-studio-dir Īnd finally, agree to the Android licenses: flutter doctor -android-licensesĪdditionally, you can check out additional Linux libraries here. IntelliJ IDEA Ultimate Edition (version 2022.1) Linux toolchain - develop for Linux desktop Android toolchain - develop for Android devices (Android SDK version 33.0.0-rc2) Flutter (Channel stable, 3.3.1, on Void Linux 5.10.138_1, locale en_US.UTF-8)Ĭhecking Android licenses is taking an unexpectedly long time. If you have already downloaded Android Studio, run flutter doctor it should give you this: Doctor summary (to see all details, run flutter doctor -v): You can verify whether your Flutter installation succeeded by running flutter -v. Or for the stable branch: git clone -b stable Alternatively, you can do it using git: git clone ![]() ![]() If you use Linux, simply download the tarball, extract it, and add it to your PATH. ![]() Table of Contentsįlutter SDK ships with Dart, and so you don't need to install it separately.Īnd choose your operating system. The blog has gotten lengthier than I thought, so here's a table of contents for better navigation. If you're here, you probably know what Flutter is, so let's skip that and move straight up into the development environment setup. These are a few questions we will have a look at the solutions of on our journey to becoming a Flutter developer. Why Dart? What is hot reload? What are widgets? How is the development experience? How is compose similar to flutter? Is native development dead? This blog is my journey as a native android developer that went on to learn Flutter. Declarative UI is the answer, and this is the reason me and a large part of the industry have shifted to Jetpack Compose and Flutter. ![]() The modern generation requires a beautiful yet powerful UI which XML wasn't meant to solve. I have been doing native Android development since 2019, starting with XML and now with Jetpack Compose. It supports platforms like iOS, macOS, Android, Web, Linux, Windows, and Fuchsia. Flutter is an open-source UI toolkit created by Google to build and ship beautiful yet powerful applications across platforms with a single codebase.
