Leveraging Apple's System APIs and Frameworks

When you come from iOS development, you might need to find Flutter plugins that offer the same abilities as Apple’s system libraries. This might include accessing device hardware or interacting with specific frameworks like HealthKit or MapKit.

For an overview of how the SwiftUI framework compares to Flutter, see Flutter for SwiftUI developers.

Introducing Flutter plugins

Dart calls libraries that contain platform-specific code plugins. When developing an app with Flutter, you use plugins to interact with system libraries.

In your Dart code, you use the plugin’s Dart API to call the native code from the system library being used. This means that you can write the code to call the Dart API. The API then makes it work for all platforms that the plugin supports.

To learn more about plugins, see Using packages. Though this page links to some popular plugins, you can find thousands more, along with examples, on pub.dev. The following table does not endorse any particular plugin. If you can’t find a package that meets your need, you can create your own or use platform channels directly in your project. To learn more, see Writing platform-specific code.

Adding a plugin to your project

To use an Apple framework within your native project, import it into your Swift or Objective-C file.

To add a Flutter plugin, run flutter pub add package_name from the root of your project. This adds the dependency to your pubspec.yaml file. After you add the dependency, add an import statement for the package in your Dart file.

You might need to change app settings or initialization logic. If that’s needed, the package’s “Readme” page on pub.dev should provide details.
