I met a problem where when I build the application, it shows there is error where the package is not exists. I am using the example code that provided at pub dev of the dependency flutter_secure_storage. I have already change the minSdkVersion to 18.
Can I know is there any ways to fix this problem?
android\app\src\main\java\io\flutter\plugins\GeneratedPluginRegistrant.java:16: error: package com.it_nomads.fluttersecurestorage does not exist
flutterEngine.getPlugins().add(new com.it_nomads.fluttersecurestorage.FlutterSecureStoragePlugin());

after some search through Google, I have found a solution for my issue through Github. It could be some problem in the pub-cache folder. I follow the comment from one post in Github and deleted flutter_secure_storage inside the pub-cache folder and reinstall and it won't show the error anymore.

i show only error message.
What i can do to fix this problem ?
I already tried to flutter clean, flutter pub cache repair, restart laptop, reinstall android studio, and reinstall android emulator.
I'm new to flutter dev and android studio, so basically whenever i run my app on windows(desktop), my app opens for 20sec on windows but then gets closed automatically.
It shows :
"LOST CONNECTION TO DEVICE" ,
I don't know what is the problem !? I didn't even have the app.so file present in any folder, I had to ask a friend to mail me this file, and even after pasting the file in the
build->windows->runner->debug folder, it's showing the same error.
flutter doctor -v result is :

In Android Studio, I get this error message when trying to start a new Flutter App.
Android Studio error message
I can't figure out why it's not working. I can run the default Android Studio flutter app in the Android Virtual Device fine.
?
same thing happened to me when i pointed the path
as
/home/ekele/flutter_sdk/bin
it worked when i changed it to
/home/pompidou/flutter_sdk
change the path below to C:\Users\kaste\Documents\flutter
As said before, you need to set 'flutter installation directory' (you got it as can be shown at your flutter doctor -v command output:
Flutter version 2.2.0 at C:\Users\kaste\Documents\flutter.
Problem is you are setting as flutter SDK your Android SDK installation directory, which is wrong. You need to just set C:\Users\kaste\Documents\flutter instead of C:\Users\kaste\AppData\Local\Android\sdk
I am new to flutter and everything was working fine for me until I updated flutter today from 2.0.1 to 2.0.3 when I started to get this error I tried everything from configuring the adb manually and everything I could get on stack overflow. Can anybody help me with this error it will be a great help for me.
