For the Flutter app I’m working on, the company had a third party develop native Android and iOS code for an alarm to integrate into our app. I ran their sample app that they made and it ran just fine.
I copied the code over to my project and kept getting this error.

So, I created a new project and copied the code over and it worked great. While doing some troubleshooting, we found out that this issue sometimes appears with dependencies having issues with each other, so I copied all my dependencies from my app to the new project and got the same error. After commenting out dependencies to find which one may be causing the issue, I landed at the audio_service package. We did some more searching through forums and all, but weren’t able to figure out a solution.
Has anyone run into this issue before and been able to figure out what’s going on? Or have any ideas of what I can try?
I got the recommendation of having the other developers redo the native stuff with a different dependency, but I'm hoping to avoid that if possible.

delete the application on your emulator (or wherever you work)
execute
flutter clean
in your working directory and rebuild the app.
flutter sometimes does not recognize plugins automatically.
I had this error and deleting app on device/simulator and installing it again helped me
I recently added quick_actions plugin works fine in debug mode but shows a blank screen in release mode.
Found these issues in the log.

I found the same issue for google_fonts package. As of now to remove this issue from the release mode I added shrinkResources false in the app level build.grade file of android folder. Let me know if this helps.

STEP 1 : Ensure you have imported the plugin by including this in your pubspec.yaml file
image_picker: ^0.6.7+4
STEP 2 : Make sure you have imported the plugin in the file you need it
import 'package:image_picker/image_picker.dart';
STEP 3 : Make sure you run this command
flutter pub get
Now, many times in Flutter even after doing the above 3 steps perfectly you will get the same error.
Here is my solution that has worked for me.
STEP 1 : Run this command in the terminal
flutter clean
STEP 2 : CLOSE/STOP your emulator and start it again
99% of the time this works for me.
just click stop red icon right side of run icon. and restart app
