How do you talk to native code from within a Flutter app?

Posted by Jennifer | Updated on

Normally you don’t need to talk to native code because the Flutter framework or third party plugins handle it. However, if you do find yourself needing to get special access to the underlying platform, you can use platform channels.

One type of platform channel is a method channel. Data is serialized on the Dart side and then sent to the native side. You can write native code to interact with the platform before sending a serialized message back. That message might be written in Java or Kotlin on Android or Objective-C or Swift on iOS.
