Android: Way to block set of URL

Do we have any way to block a set of URL. I want to open anything which is not from my domain in different browser or app available on the mobile.
I can do this on iOS by listening to shouldStart and then using url_laucher for anything which is not my domain. However for Android, I dont even get control for 'shouldStart' state.

Do we have anything which I can listen to for stopping loading URL? I can still use url_launcher, but it would also open in my application currently. Please suggest.

まず、issue にある既存の iOS の `shouldStart` と `url_launcher` のアプローチを確認し、次にこの plugin における Android WebView の URL 読み込みのエントリーポイントを追跡します。ユーザーのドメイン外の URL を別のブラウザまたはアプリで開ける一方で、ユーザーのドメインの URL は引き続き WebView で開けるようになれば完了です。
