3. Flutter flaunts beautiful UI with support for tons of Material and Cupertino Widgets.
4. But what happens when that crazy feature you want to build into your app isn’t supported by the Flutter SDK?
5. Flutter doesn’t only come with beautiful UIs but also comes with interoperability with native platform APIs.
6. So while all the features your app needs might not be supported, Flutter has Platform Channels.
7. Platform Channel makes it possible to exchange data between Flutter and native Android and iOS APIs.
8. How To Use Flutter Platform Channel
9. Invoke a method on the client Write Android specific code using Java/Kotlin 2 3 4 Write iOS-specific code using Objective-C/Swift Create a Platform Client. 1
10. class _DashboardState extends State<DashboardPage> { static const platform = const MethodChannel('awesome.app.com'); // Invoke a method on the platform. } Typing... 1
11. String deviceVersion = await platform.invokeMethod('getDeviceVersion'); Typing... 2
12. private val CHANNEL = "awesome.app.com" MethodChannel(flutterView, CHANNEL).setMethodCallHandler { call, result -> when (call.method) { "getDeviceVersion" -> { result.success(BuildConfig.VERSION_CODE.toString() else - > result.notImplemented() } } Typing... 3
13. let channel = FlutterMethodChannel(name: "awesome.app.com", binaryMessenger: controller) channel.setMethodCallHandler({ (call: FlutterMethodCall, result: FlutterResult) -> Void in switch call.method { case "getDeviceVersion": result(UIDevice.current.systemVersion) default: result(FlutterMethodNotImplemented) } }) Typing... 4
