Flutter web5/18/2023 ![]() Let's build a Flutter app from scratch! If you’re new to Flutter, you’ll be introduced to the framework through setting up the dev environment, building a starter app, and running it in your browser. The Flutter team and community also provide easy-to-follow documentation with straightforward step-by-step breakdowns, and written and video tutorials. It enjoys strong support from Google and has a vibrant community. Therefore, it’s much easier to maintain updates and add new features when you build a Flutter web app.įlutter performs extremely well across different platforms because it applies each platform’s native code without the need for an intermediary layer to interpret it. It’s a single programming language that can develop apps for Android, iOS, and the web, which means you only need one codebase. However, it’s easy to pick up and has some distinct advantages over other languages. If you’re not already familiar with Dart, learning an entirely new language might seem like an extra chore. Flutter is built using the Dart programming language, so to use Flutter you need to know Dart. It’s one of the most-used mobile development frameworks. Add the following code, which sets up a not-yet-complete, count-the-number-of-stars-on-a-GitHub-repo app: lib/main.dart import 'package:flutter/material.Flutter is a development framework that allows developers to build applications across various platforms, namely Android, iOS, and the web. Delete all of the code from lib/main.dart, which creates a Material-themed, count-the-number-of-button-presses app. Removing the mobile and desktop runners will eliminate the need to select which platform to run this project on $ rm -r android ios linux macos windows This project is designed to work with Flutter for the web. $ flutter pub add githubįinally, add the intl dependency. $ flutter pub add flutter_markdownĪdd the github dependency. These packages are no longer being depended on:Īdd the flutter_markdown dependency. Remove the cupertino_icons dependency, as this project isn't targeting iOS. ![]() Note: The code for this codelab uses a plugin, so you can't use DartPad.įor this codelab, we provide much of the starting code so that you can quickly get to the interesting bits.Ĭreate a Flutter project called star_counter as follows. You will debug your code using Dart DevTools on Chrome. You can use your preferred editor, such as Android Studio or IntelliJ with the Flutter and Dart plugins installed, or Visual Studio Code with the Dart Code and Flutter extensions. You need three pieces of software to complete this lab: the Flutter SDK, an editor, and the Chrome browser. For more information about packages and plugins, see Flutter Plugin or Dart Package? As previously mentioned, a plugin is a type of a package. (In fact, Flutter supports federated plugins, which allow support for different platforms to be split across packages.)Ī package is a Dart library that you can use to extend or simplify your app's functionality. Plugin packages can be written for Android (using Kotlin or Java), iOS (using Swift or Objective-C), web (using Dart), macOS (using Dart), or any combination thereof. I'm looking for an explanation of something specific.Ī plugin (also called a plugin package) is a specialized Dart package that contains an API written in Dart code combined with one or more platform-specific implementations. I'm looking for example code to use in my project. I know something about this topic, but I want a refresher. What would you like to learn from this codelab? I'm new to the topic, and I want a good overview. If you are new to Flutter, you might want to first start with Write your first Flutter app on the web. Prerequisites: This codelab assumes that you have some basic Flutter knowledge. ![]() ![]() How to debug a web app using Dart DevTools.The difference between a package and a plugin.How to use a Flutter plugin in a web app.Finally, you'll use a Flutter plugin to launch the app and open the hosted privacy policy. You'll learn how to host your app on Firebase. You'll use Dart DevTools to do some simple debugging. In this codelab, you'll finish an app that reports the number of stars on a GitHub repository. Flutter is Google's UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. ![]()
