Using Angular's ElementRef to set focus on an ion-textarea: "The 'setFocus' property is not found on the 'ElementRef' type."

After developing a textarea component that automatically focuses itself when created using the ngAfterViewInit() method, everything seemed to be working perfectly as expected.

ngAfterViewInit() {
    if(this.text.length===0){
    this.theinput.setFocus();
    }
  }

The implementation was straightforward - I used ElementRef to access the ion-textarea component:

@ViewChild('name') theinput: ElementRef;


<ion-textarea #name rows="1" ></ion-textarea>

However, upon running ionic serve and building the app, an error popped up:

"Property 'setFocus' does not exist on type 'ElementRef'."

This issue occurred at the line of code where this.theinput.setFocus() was called.

A temporary fix involved commenting out the problematic line, rebuilding the app, and then uncommenting it. This solution worked but was not ideal.

Seeking a more efficient workaround, one possible solution could involve extending ElementRef or exploring similar alternatives?

Utilize the ViewChild decorator to access the DOM element

@ViewChild('ref') ref:TextInput;

Then, use nativeElement which represents a textarea in the DOM and includes a focus method.

ngAfterViewInit() {
    if(this.text.length===0){
    this.ref['_native'].nativeElement.focus();
    }
  }
