Shrinker error

So I just came across this error while I was trying to integrate google sign in into one of my Flutter app.

shrinker may have failed to optimize the Java bytecode.
To disable the shrinker, pass the ` — no-shrink` flag to this command

The error that you get.

So, to solve this error just navigate to {your-app-name}\android\app\build.gradle, when you get to the build.gradle file just scroll down to where defaultConfig was specified and change the minSdkVersion from 16 to 21 and the problem is gone.
