Is it just another mobile app development platform? Is it going to make existing technology obsolete? Is this the way that mobile app development will progress? And, if so, how can I use it to create apps that delight my users and skyrocket my business?
In this article, we’ll answer all these questions and more as we dive into everything you need to know about Flutter, including what it does, why you should use
What Do you know about Flutter?
Flutter is a cross-platform application development framework created by Google. It allows developers to create high-quality native applications for both iOS and Android with a single codebase. Flutter is known for its speed, simplicity, and extensibility.
Additionally, Flutter provides a rich set of Material Design and Cupertino (iOS) widgets that can be used to build beautiful apps with a great user experience. Also, Flutter comes bundled with an IDE named Dart which has a plugin for most popular IDEs like IntelliJ IDEA, VS Code, and Sublime Text.
The language is compiled into native ARM or x86 machine code so it can be run on any modern processor architecture. Finally, Flutter makes use of the Feathers UI Toolkit and the 2D graphics package Skia Graphics Engine (an open-source project).
How Flutter works
Flutter is a powerful toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. It is free and open source, created by Google.
Flutter not only enables you to create incredible apps, but it also makes it possible to do it rapidly and effectively. In addition, Flutter provides a rich set of Material Design and Cupertino (iOS-flavored) widgets that support both material design principles and iOS human interface guidelines.
Plus, with Flutter’s hot reload feature, you can make changes to your code and see the results instantly without having to restart your app or lose your place. And when you’re done coding, Flutter’s gesture recognizer APIs let your users interact with an app on their terms.
That means they don’t have to learn an entirely new way of doing things just because they picked up your phone instead of their laptop or tablet.
We need technologies like Flutter to adapt with us as we start moving away from PCs and laptops because the world has changed. This is only one instance of how technology changes over time: what was once a niche business may soon become mainstream.
Why to learn Flutter
Flutter is a new way to build high-quality, native apps for iOS and Android from a single codebase. With Flutter, you can write one codebase that compiles to both platforms, saving you time and effort.
Plus, Flutter’s hot reload helps you quickly and easily experiment, build UIs, add features, and fix bugs faster. Lastly, Flutter is open source, so you can always get help from the community if you need it. A long time ago, developers could only create one type of app with HTML5: websites.
However, we now have additional choices, including mobile applications with user evaluations on our phones and several frameworks like React Native (which is similar to flutter). For many people, HTML5 was sufficient but this has changed as companies want more control over how their mobile app behaves.
This has created a huge shift in the market where developers are now thinking about which framework will best suit their needs rather than just picking what they know or what their company provides them with.
In addition, companies have begun releasing tools to help make it easier for developers to make decisions based on what they need from an app or what platform they’re developing for.
Mobile app development with Flutter
The development of mobile apps has never been easier thanks to Flutter. Flutter-created apps are quick and responsive.
Additionally, because you don’t need to individually build for two different platforms, the development process is quicker. That means you can write one codebase and have it compile to two different platforms.
Not only that, but Flutter also has amazing performance. Flutter-created apps are quick and responsive. Additionally, because you don’t need to individually build for two different platforms, the development process is quicker.
And what’s even better? You don’t need any extra tools or frameworks to get started. You just use Dart, which is already included in Flutter. When developing an app with Flutter, there’s no need for frameworks like CocoaPods or Kotlin, or Java.
Everything is included as part of the package so developers can focus on building their apps instead of searching for additional software and frameworks to help them along the way.
Creating your first application with Flutter
When you create a new Flutter project, you are given a choice of two templates: material and Cupertino. Material is the design system used by Google for its Android applications. Apple uses the Cupertino design system for its iOS applications. A Blank application is just that, an empty canvas waiting for your code.
A Single Page App (SPA) is created using the Material Template, while an iOS application would be created using the Cupertino Template. The Blanks application doesn’t come with any predefined content so we need to manually add a page to it. We’ll call this page Hello World.
To add pages to our app we first need to go into our pub spec file and make sure that we have defined at least one route (i.e., URL) for our app’s initial page lets switch from the /home/ route to the /hello-world/ route.
Within our main. dart file, after defining the build method and before calling run app(), we will define a new method called _createPage().In this way, we’ll combine many Flutter widgets to produce a straightforward hello world app. Here is what our code should look like now
What do you need to develop mobile apps with Flutter?
To develop mobile apps with Flutter, you’ll need a Mac and Linux machine for the iOS setup, or a Windows machine for the Android setup. You’ll also need the Flutter SDK, an IDE, and a code editor.
Next, you should set up your development environment on your computer: download Xcode from Apple’s developer site if you’re on a Mac, or get Android Studio from Google’s developer site if you’re on Windows.
After that, use Homebrew to install the Flutter SDK package (this is done by running brew install flutter at the terminal). Then install either IntelliJ IDEA (for macOS) or JetBrains’ CLion (for Linux) as your IDE and open it to create a new project.
After that’s done, open Terminal and type flutter doctor to make sure everything is set up correctly; after this step finishes successfully there should be no red warnings in Terminal except those about platform-specific issues such as Xcode installation problems.
Where can I learn more about this technology?
Flutter is a new technology created by Google that allows developers to create high-quality native apps for both iOS and Android.
This is a game changer because it means that developers can now create one app that will work on both platforms, instead of having to create two separate apps. Plus, Flutter apps are faster and more responsive than traditional apps.
If you’re interested in learning more about this technology, there are a few great resources out there. First, you should check out the book from the author of Kotlin: Modern App Development with Kotlin.
And if you want to learn more about Flutter itself, make sure to check out its official website. There’s also an excellent video tutorial series from Udacity which goes into detail about how to use the framework.
