Convert your website into an application in a few minutes (FLUTTER WEBVIEW).

Hmm 🤔 Kind of, but you're not doing any harm to the owner because you can't access anything(e.g database) on the website, webview is just like your normal browser but a webview app-only access one URL you put in your code. As a matter of fact, you're even doing the owner a favor because if many users download the app on the play store, they are only registering on the person's website, not on your app so all the traffic is going to the person website not on your app, although traffic comes to the app if you have many downloads.
