This kind of issue usually appears either due to a gradle misconfig or in your case, it looks more of an internet issue.

Try running flutter clean in your project source and then using flutter build appbundle and check whether you're able to run the command without any errors.

In case, you're still facing any errors, go to android/build.gradle in your flutter project and edit this line

from classpath 'com.android.tools.build:gradle:3.5.0'

to classpath 'com.android.tools.build:gradle:3.4.2

Then repeat the above steps again with flutter clean and flutter build appbundle. It should work.
