How to get my flutter app to realize that it was started with a different intent?

I have a Flutter app which, like a browser, can be started from either the launcher or through a URI intent.

I have two files. The Dart file containing the main code and the Kotlin file containing the intent catching code.

My Kotlin code looks like:

class MainActivity : FlutterActivity() {
    override fun onResume() {
        super.onResume()
        print("got at resume ${intent.data}")
    }
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        print("At onCreate: ${intent.data}")
        GeneratedPluginRegistrant.registerWith(this)
        MethodChannel(flutterView, CHANNEL).setMethodCallHandler { call, result ->
            print("got at onCall ${intent.data}")
    }
}

So when I start it the first time, it outputs At onCreate: null". Makes sense, I started it without an intent.

Then I run adb shell am start -d "https://www.example.com". I expect it to (and when I wrote a demo Android app, it did) output print("At onCreate: https://www.example.com").

However, when I run it as a Dart app, I get FlutterActivityDelegate: onResume setting current activity to this. Even when I send it to background and then run adb shell..., I get got at resume null.

The only way for me to get At onCreate: https://www.example.com was to remove it from the previous app list. Then, and only then did I get the right output.

But even then, running adb shell am start -d "https://www.example.com/123" produces the same bug as above.

How can I get the "new" intent in Dart/Kotlin?

In your AndroidManifest.xml the android:launchMode is relevant. If it's set to singleTop, the Activity will receive a call to onNewIntent(Intent):

Note that getIntent() still returns the original Intent. You can use setIntent(Intent) to update it to this new Intent.
