| 2 | +title: Leveraging Apple's System APIs and Frameworks |
| 3 | +description: Learn about Flutter plugins that offer equivalent functionalities to Apple's frameworks |
| 4 | +--- |
| 5 | + |
| 6 | +When you come from iOS development, you might need to find |
| 7 | +Flutter plugins that offer the same abilities as Apple's system |
| 8 | +libraries. This might include accessing device hardware or interacting |
| 9 | +with specific frameworks like `HealthKit` or `MapKit`. |
| 10 | + |
| 11 | +<!-- Add once SwiftUI PR is merged --> |
| 12 | +<!-- For an overview of how the SwiftUI framework compares to Flutter, |
| 13 | +see [Learning Flutter as a SwiftUI developer][]. --> |
| 14 | + |
| 15 | +### Introducing Flutter plugins |
| 16 | +Dart calls libraries that contain platform-specific code _plugins_. |
| 17 | +When developing an app with Flutter, you use _plugins_ to interact |
| 18 | +with system libraries. |
| 19 | + |
| 20 | +In your Dart code, you use the plugin's Dart API to call the native |
| 21 | +code from the system library being used. This means that you can write |
| 22 | +the code to call the Dart API. The API then makes it work for all |
| 23 | +platforms that the plugin supports. |
| 24 | + |
| 25 | +To learn more about plugins, see [Using packages][]. |
| 26 | +Though this page links to some popular plugins, |
| 27 | +you can find thousands more, along with examples, |
| 28 | +on [pub.dev][]. The following table does not endorse any particular plugin. |
| 29 | +If you can't find a package that meets your need, |
| 30 | +you can create your own or use platform channels directly in your project. |
| 31 | +To learn more, see [Writing platform-specific code][]. |
| 32 | + |
| 33 | +### Adding a plugin to your project |
| 34 | +To use an Apple framework within your native project, |
| 35 | +import it into your Swift or Objective-C file. |
| 36 | + |
| 37 | +To add a Flutter plugin, run `flutter pub add package_name` |
| 38 | +from the root of your project. |
| 39 | +This adds the dependency to your [`pubspec.yaml`][] file. |
| 40 | +After you add the dependency, add an `import` statement for the package |
| 41 | +in your Dart file. |
| 42 | + |
| 43 | +You might need to change app settings or initialization logic. |
| 44 | +If that's needed, the package's "Readme" page on [pub.dev][] |
| 45 | +should provide details. |
