Ionic v4 - Use Keyboard on pages

Ionic Framework ionic-v3
1

Hello,

Currently in a project which work with Electron and Ionic, i am trying to use an ionic keyboard to be able to write in a input.

I try to use the ionic Keyboard included in Ionic v4 like that:

app.module.ts

import { Keyboard } from '@ionic-native/keyboard/ngx';
@NgModule({
  [...]
  ],
  providers: [ 
    (...),
    Keyboard
  ],
});

my-page.ts

import { Keyboard  } from '@ionic-native/keyboard/ngx';
import { IonInput } from '@ionic/angular';
@ViewChild('input') InputK: IonInput;

constructor( private keyboard: Keyboard) {
}
public showKeyboard(){
   this.keyboard.setFocus()
}

On the input in my html i just put (click)=‘showKeyboard()’ but i won’t work…

I’ve you got solution for this kind of problem ?

Kind Regards for your time.
