Same issue

I have the same issue on Android. Somehow I suspect that the root cause is the same as of flutter/flutter#153075 there however is the root cause not found yet.

That's interesting. One reply there suggested running flutter clean

[rekire]

I did that multiple times. I also deleted my App multiple times and even Flutter. My current theory is that something breaks the initialization of the method channels.

[rekire]

As expected, in my app is the FlutterSecureStoragePlugin's method onAttachedToEngine() is not called, that is why the the method channel is not found. Digging deeper...

[rekire]

Okay got it repaired, but not sure why it broke.
I'm calling there the GeneratedPluginRegistrant.registerWith(flutterEngine) in my MainActivity and it starts working again. The most interesting question is why this is necessary and why it broke.

My simplified code is like this:

class MainActivity: FlutterActivity() {
    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        GeneratedPluginRegistrant.registerWith(flutterEngine)
    }
}

(I removed the part regarding a custom Application since that is not related as I found out later)

This flutter clean fixed it for me. I was happily using flutter run -d chrome but a release build flutter build web was hitting this error in chrome when loading from the prod web server. Seems the flutter clean just prior to the flutter build web gives me a working release build...
