Ion-content adjust the screen resolution Ionic 4

#1

I would like my ion-content adjusted to the size of the screen. In this case, fill in and do not leave that void at the bottom.

Example with a large resolution:

u73u0

Hence if the height of the screen is smaller, it causes to do scroll, getting that part white, because the bottom does not fill when it does screen scroll
