Upgrading pre 1.12 Android projects based on Kotlin
My old Flutter app has been complaining I need to do this migration for a while. Today I finally decided to do it.
Based on the criteria listed in the documentation, I determined that I should follow step 1b. However, the snippet was in Java, and my MainActivity was written in Kotlin.
I'm useless at Kotlin and the doc doesn't include a snippet in that language. Luckily someone else posted the corresponding snippet on a GitHub ticket.
Java snippet:
@Override
public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
GeneratedPluginRegistrant.registerWith(flutterEngine);
new MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), CHANNEL)
.setMethodCallHandler(
(call, result) -> {
// Your existing code
}
);
}
The Kotlin equivalent:
public class MainActivity extends FlutterActivity {
@Override
public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
GeneratedPluginRegistrant.registerWith(flutterEngine);
}
}
I tried it in my app and it worked fine.
And I filed this ticket so that the Flutter team can include the snippet in their official documentation.
