When using flutter_blue package and trying to build android appBuild fails with an exception. This i-CodePudding

I am trying to use flutter_blue package in flutter application. It is easily added to the dependencies but when I try to build the app after adding this package an exception occurs. I have done all the required setups for this package like, setting minSdkVersion 19 and asking for permissions for bluetooth.

Bellow, I have shared screenshot as well as text of the error that is coming as well some other codes

I only have a main.dart file, which has nothing to do with the flutter_blue package for now so I have not posted its code.

Try moving the permissions outside of application tag, like this.

<manifest>
   <uses-permission android:name="android.permission.BLUETOOTH" />  
   <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />  
   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>  
<application>
     ....
</application>
