Ionic Keyboard Attach Directive
import { Directive, ElementRef, Input, OnDestroy, OnInit } from '@angular/core';
import { Keyboard } from '@ionic-native/keyboard';
import { Content, Platform } from 'ionic-angular';
import { Subscription } from 'rxjs/Subscription';
/**
* @name KeyboardAttachDirective
* @source https://gist.github.com/Manduro/bc121fd39f21558df2a952b39e907754
* @description
* The `keyboardAttach` directive will cause an element to float above the
* keyboard when the keyboard shows. Currently only supports the `ion-footer` element.
*
* ### Notes
* - This directive requires [Ionic Native](https://github.com/driftyco/ionic-native)
* and the [Ionic Keyboard Plugin](https://github.com/driftyco/ionic-plugin-keyboard).
* - Currently only tested to work on iOS.
* - If there is an input in your footer, you will need to set
* `Keyboard.disableScroll(true)`.
*
* @usage
*
* ```html
* <ion-content #content>
* </ion-content>
*
* <ion-footer [keyboardAttach]="content">
* <ion-toolbar>
* <ion-item>
* <ion-input></ion-input>
* </ion-item>
* </ion-toolbar>
* </ion-footer>
* ```

Ionic 5 quickfix for components that return HtmlElement (ion-alert, ion-popover, etc...)

My Fix on this was adding a hide and show when the user clicks on the input.
isPlatform('ios') && isShow <>content that overlaps</>
by this the overlap content hides whenever the user click the input and show when the user leaves the input by clicking the screen.
