Android app submission was rejected. Issue: Violation of Device and Network Abuse policy

I have created a complete app using webview plugin. When I submit it to google play-store it has rejected. The only thing I did was create a website and load it through flutter webview. So I think something wrong in this plugin.

This is the content in email I got.

Publishing status: Rejected

After review, your app has been rejected and wasn't published due to a policy violation. If you submitted an update, the previous version of your app is still available on Google Play.

Issue: Violation of Device and Network Abuse policy
--
We don’t allow apps that interfere with, disrupt, damage, or access in an unauthorized manner the user’s device, other devices or computers, servers, networks, application programming interfaces (APIs), or services, including but not limited to other apps on the device, any Google service, or an authorized carrier’s network.

Google Play の却下テキストと、アプリが Flutter WebView plugin を通じてウェブサイトを読み込むという報告から始めてください。ソースファイル、テスト、エントリーポイントは特定されていないため、plugin の変更が妥当かどうかを判断する前に、plugin の動作を Google の Device and Network Abuse policy と比較してください。
