FLUTTER INSTALL PLUGIN SOFTWARE
You need two pieces of software to complete this lab: the Flutter SDK and an editor. I'm looking for an explanation of something specific.
FLUTTER INSTALL PLUGIN CODE
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.
FLUTTER INSTALL PLUGIN HOW TO
How to publish your plugin so that others can use it.How to write an app that uses your plugin.How to write a Flutter plugin for iOS and Android.You'll implement a simple music plugin that processes audio on the host platform, and then you'll make an example app that uses your plugin to make a music keyboard. In this codelab, you'll learn how to author your own plugins for iOS and Android.
Flutter provides a mechanism for authoring plugins that allows you to communicate with platform-specific code and also allows you to publish your plugins on pub.dev so that others can use them. For example, you might want to communicate with a database that doesn't have a Dart library written for it. Some Flutter developers may never write a plugin.įlutter makes it easy for users to interact with cross-platform Dart libraries, but sometimes it's ideal to interact with platform-specific code. Note: This is an advanced topic and is not intended for Flutter beginners. The Flutter Favorite Favorites tag identifies plugins that you should first consider when building your apps. In particular, you should check out the Flutter Favorite packages and plugins. The authors of the Flutter SDK, as well as members of the Flutter community, have written many plugins and published them to pub.dev to share them with the community. You should first check pub.dev to see if the plugin you need already exists. Plugins are an important part of the Flutter ecosystem. For example, you might want your mobile app to interact with the camera on your device. Adding new methods to this interface will break platform implementations that 'implement' it therefore, extending this class assures that the subclass gets the default implementation.Welcome to the "How to write a Flutter plugin" codelab!Ī plugin is a piece of software that adds capabilities to your app. In order to avoid breaking changes, platform implementations should extend this class rather than implement it. Import 'method_channel_url_launcher.dart' Import 'package:plugin_interface_platform.dart' Now run the following code in the current directory you created earlier to create the platform interface package. For example, the URL launcher plugin can be moved to a federated sub-folder in the packages directory. We will be creating a directory that contains the plugin package, the platform interface, and web packages. First, we will develop the platform interface package and restructure the code to use a federated plugin directory arrangement. The plugin sits in a directory like packages/URL launcher in the flutter/plugins directory on the GitHub repository.
Additionally, platform interfacing explains how the plugin package communicates with the platform implementation and replaces what the plugin package needs from the platform. Platform interfacing is the process of abstracting what plugin package is to be implemented via its platforms. On the other hand, a package can use plugins if it so chooses. A flutter plugin contains just Dart code, while a package only contains Native code.
Federated plugins are created in this manner.īy reorganizing your plugin as a federated plugin, anyone can add support for new platforms without needing to do so yourself. When constructing Flutter plugins, platform-specific implementations are divided into different packages. This tutorial will show you how to create a web plugin using Flutter. In addition to translating Dart to JavaScript, adding web functionality to Flutter requires the inclusion of fundamental graphics layer on top of conventional browser APIs.
FLUTTER INSTALL PLUGIN ANDROID
For example, you can create apps for iOS and Android that can then be converted to run on the web. Flutters web support enables a seamless online experience.
