I have found a way to do it.

in .ts file define two boolean variables.and change value on focus and focus out event of input element.

home: boolean = false;
edit:boolean = true;

onFocusOutEvent(event: any){
// toggle as you want to use it.
}
onFocusEvent(){
// toggle as you want to use it.
}

in HTML file

<input matInput type="text" [formControlName]="element.id" (focusout)="onFocusOutEvent($event)" (focus)="onFocusEvent($event)" >

<button style="float: right;" color="primary" *ngIf="edit">
     <mat-icon>edit</mat-icon>
</button>
<button *ngIf="home" style="float:left;">
<mat-icon>home</mat-icon>
</button>

i hope it's helpful for someone. thank you
