我在我的项目中正常使用angular的最新版本中的Mat Autocomplete并得到这种类型的错误

Question

    <form class="example-form">
      <mat-form-field class="example-full-width">
        <input type="text" placeholder="Pick one" aria-label="Number" matInput [formControl]="myControl" [matAutocomplete]="auto" for="id" >
    </mat-form-field>
        <mat-autocomplete #auto="matAutocomplete" id="id">

          <mat-option *ngFor="let option of options" [value]="option">
            {{ option }}
          </mat-option>
        </mat-autocomplete>

    </form>


import { Component, OnInit } from '@angular/core';
import { FormControl } from '@angular/forms';
@Component({
  selector: 'app-auto',
  templateUrl: './auto.component.html',
  styleUrls: ['./auto.component.css']
})
export class AutoComponent implements OnInit {


  constructor() { }

  ngOnInit() {
  }
  myControl: FormControl = new FormControl();

  options = [
    'One',
    'Two',
    'Three'
  ];

}

I am getting this error when i am using it in my project in which i used material design bootstrap .

You are using id but never declared it anywhere.

ts:

public id = 'my-input';
