Friends here is the code snippet and please use this carefully to avoid mistakes:

1. Firstly friends we need fresh angular 13 setup and for this we need to run below commands but if you already have angular 13 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

npm install -g @angular/cli

ng new angularmaterial

cd angularmaterial

ng serve --o

//Here is the url, you need to run into your browser and see working angular test project

2. Now friends we need to run below command into our project terminal to get angular material and its related modules:

ng add @angular/material

ng serve --o

3. Finally friends we need to add below code into our project/src/app/app.component.html file to get the final output on web browser:

<form [formGroup]="myForm" (ngSubmit)="onFormSubmit()">
  <mat-form-field appearance="fill">
      <mat-label>User Name</mat-label>
      <input matInput formControlName="unameFormControl">
      <mat-error *ngIf="myForm.get('unameFormControl').hasError('required')">
          Username is <strong>required</strong>
        <mat-error *ngIf="myForm.get('unameFormControl').hasError('minlength')">
          Min lenght <strong>8 char</strong>
    </mat-form-field><br />
    <mat-form-field class="example-full-width" appearance="fill">
      <input type="email" matInput formControlName="emailFormControl"
      <mat-error *ngIf="myForm.get('emailFormControl').hasError('email')">
        Please enter a valid email address
      <mat-error *ngIf="myForm.get('emailFormControl').hasError('required')">
        Email is <strong>required</strong>
    </mat-form-field><br />

    <mat-form-field appearance="fill">
      <input matInput formControlName="pwdFormControl">
      <mat-error  *ngIf="myForm.get('pwdFormControl').hasError('required')">
        Password is <strong>required</strong>
      <mat-error *ngIf="myForm.get('pwdFormControl').hasError('minlength')">
        Min lenght <strong>8 char</strong>
    </mat-form-field><br /><br />
    <div mat-dialog-actions>
      <button type="submit" mat-raised-button color="primary">Submit</button>

4. Now friends  we need to add below code inside project/src/app/app.module.ts file:

import {MatInputModule} from '@angular/material/input';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import {MatIconModule} from '@angular/material/icon';
import {MatButtonModule} from '@angular/material/button';
import {MatFormFieldModule} from '@angular/material/form-field';

imports: [

6. Now friends  we need to add below code inside project/src/app/app.component.ts file:

import { FormControl, Validators, FormBuilder } from '@angular/forms';

 * @title Autocomplete overview
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']

export class AppComponent {
  constructor(public fb: FormBuilder) {}
  myForm:any = FormControl;
  onFormSubmit() {
    if (this.myForm.valid) {
    } else {
  ngOnInit(): void {
    this.myForm ={
      unameFormControl: ['', [Validators.required, Validators.minLength(8)]],
      emailFormControl: ['', [Validators.required,]],
      pwdFormControl: ['', [Validators.required, Validators.minLength(8)]]
