Flutter: Get data from native activity to Flutter Widget?-CodePudding

I have a Flutter app that lunch a native activity that contains a form (first and last name fields), when I fill in the fields and click the finish button I want to get these data back to Flutter widget.

Basically, all what I did, was lunch the FormActivity, how can I get the form data from FormActivity and display them on my Flutter widget?

override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)

        MethodChannel(flutterEngine.dartExecutor.binaryMessenger, CHANNEL).setMethodCallHandler {
                call, result ->
            if (call.method == "lunchActivity") {
               
                val intent = Intent(this, FormActivity::class.java)
                startActivity(intent)


            }
        }
    }

CodePudding user response：

Use startActivityForResult to launch an activity, return a result from the activity with setResult, implement ActivityResultListener to handle the result and finally call success on a channel to return the result to Flutter side.

See details for Flutter - Android communication.
