dart - Flutter: disable screenshot capture for app

Question

I am making a Flutter app and I need to make sure the user is not able to capture screenshot of the app (any screen). Is there any way to achieve this in Flutter or do I need to write native code for both Android and IOS?

1. Locate your MainActivity class inside the embedded android project dir in your Flutter Project
2. Add the following import to your main activity class: import android.view.WindowManager.LayoutParams;
3. Add the following line to your MainActivity's onCreate method: getWindow().addFlags(LayoutParams.FLAG_SECURE);
