According to Google's own statements, Flutter may be a mobile app SDK for creating high-quality native interfaces for Android and iOS in record time. Flutter applications are written in darts and may finally be packaged into iOS and Android applications. Dart is additionally an in-house development from Google, which is specially tailored for the event of front-end applications and may even be used, for instance , for programming Angular.
Flutter is Google’s framework for cross-platform development. It therefore makes it possible to develop an application only once for the different platforms: iOS and Android.
The highly advertised features of Flutter are hot reload, the immediate observation of changes to the device during programming, an in depth widget library, the planning of lovely and fluid user interfaces, and reactive programming, i.e. the asynchronous execution of operations during user interactions. the main target is therefore clear: optimal user interfaces and an honest developer experience.
The definition of Flutter is an SDK that permits you to develop mobile apps for both iOS and Android using Dart code. Developing in Flutter may be a pleasure, and leveraging it’s beautiful widgets allow you a really fast prototyping. Flutter converts your code into native code for both platforms, therefore you don’t got to add those platforms if you don’t want to.
Thanks to the Hot Reload functionality of the DART language, the build of applications is very fast, which makes compilation time almost invisible. Another time saver for developers! The advantages are therefore numerous.
Flutter is based on the DART programming language (originally called Dash), also created by Google and presented to the public in 2011.
Flutter has 2 main advantages.
1. Widgets : they allow you to simply describe the final rendering. Each object is defined independently of the parent constraints. It is its location in the code that will define its external constraints. This allows you to easily build its interface; the code is then more easily readable and maintainable.
2. The components : they have been recreated by Google. Developers have a gallery of components adapting to IOS like Android, and to different versions of OS.
Developing Flutter app.
Be it Linux, Mac or Windows, you'll work with flutter from the OS of your choice. All you would like to try to to is to satisfy system requirements and follow configuration steps mentioned here: https://flutter.io/docs/get-started/install.
Make sure that you simply have properly found out your Android Emulator and iOS Simulator from the link above.
Flutter Doctor:
To confirm that you simply have done your setup properly, we've a thing called Flutter Doctor which can check out your setup and can inform you if you've got missed anything. Instructions to use Flutter doctor is additionally mentioned in above mentioned link.
IDE:
You can work with flutter form Android Studio, Intellij Idea or VS Code.
To avoid setup conflict, confirm you employ the newest version of your IDE.
Setup — Android Studio and Intellij Idea:
Step I: your IDE attend File>Settings>Plugin>Browse Repositories.
Step II: Search and install Dart Plugin.
Step III: Search and install Flutter Plugin.
Step IV: Restart your IDE.
Step V: After you've got plugins installed, attend File>New>New Flutter Project>Flutter Application.
Step VI: Press next and you'll see that on next screen there's a field for your Flutter SDK path.
Step VII: If you've got the Flutter SDK on your system provide the trail there, if you've got not yet downloaded the SDK press install button beside that field and in few mins it'll make Flutter SDK available to you on your system.
Step VIII: Press next and you've got created your first flutter project.
Step IX: Once you're done you'll run your app from Shift F10 or from Run>Run main.dart
Setup — VS Code:
Step I: attend extensions.
Step II: Search and install Flutter extension.
Step III: Reload VS Code.
Step IV: After the plugin is installed, use Ctrl + Shift + P on Windows and Linux or Command + Shift + P on Mac OS to make a replacement project.
Step V: Well your project won’t be created initially , it'll offer you a mistake that you simply can see at heart right of the screen. therein error dialog you'll get choice to “Locate SDK” or “Download SDK” option. Choose what's appropriate for you. As in, if you've got a downloaded SDK, “Locate SDK”. alternatively choose "Download SDK".
Step VI: After fixing your SDK with VS Code try Step 4 again. It should work. Select the name for your flutter project then you'll be asked for the folder where you'd wish to create your project.
Step VIII: you're done, you've got just created your first flutter project.
Step VIII: Once you're through with everything, you'll run your code from debug section in VS Code.
