Safe areas on iphone x/11

Any idea how to prevent the safe area in case of using a cordova keyboard plugin?

If you use its config from/with F7 CLI, then when keyboard opened it will add device-with-keyboard class to HTML, so you can just add the following CSS rule:

.device-with-keyboard {
  --f7-safe-area-bottom: 0px;

What is different in using cli to classic handwriting code?

None, except CLI already has code that adds that class
