  • Please include some code or a description of the sample code and device you are resting on. This doesn't include enough details for anyone to be able to help. – rmtmckenzie Mar 18 '21 at 07:24
  • The code is working totallly fine without any errors. When I am testing debug apk on any real device it also works fine but when I build the release apk the apk get's installed but does not move respond after entering Login details.. – Nikhil Patil Mar 18 '21 at 08:00

Issue Solved!! Actually, the problem was with 'http' as SSL certificate was not included for the admin panel hence, app showed Bad state: Insecure HTTP is not allowed by platform error in some devices while it was running in my Mi note4 mobile phone.

Added android:usesCleartextTraffic="true" line in AndroidManifest.xml file inside <manifest <application android:usesCleartextTraffic="true""> </application> </manifest> tag

Edit Configuration -> Addition run arguments

--no-sound-null-safety

In main.dart file,

// @dart=2.9

Try

flutter build apk --release --no-sound-null-safety
