To avoid blinking problem use following code
its not mouseover and mouseout instead of that use mouseenter and mouseleave


**app.component.html**

    <div (mouseenter)="changeText=true" (mouseleave)="changeText=false">
      <span *ngIf="!changeText">Hide</span>
      <span *ngIf="changeText">Show</span>
    </div>

**app.component.ts**

@Component({
   selector: 'app-main',
   templateUrl: './app.component.html'
})
export class AppComponent {
    changeText: boolean;
    constructor() {
       this.changeText = false;
