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. Now friends we need to add below code into our project/src/app/app.module.ts file to import the angular material form fields for responsive layout and its related modules:

import { DialogOverviewExampleDialog } from './app.component';
import { NgModule } from '@angular/core';
import {MatFormFieldModule} from '@angular/material/form-field';
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 {MatDialogModule} from '@angular/material/dialog';

  declarations: [
  imports: [


4. Now friends we need to add below code into our project/src/app/app.component.ts file :

import {Component, ViewChild,  Inject} from '@angular/core';
import {ErrorStateMatcher} from '@angular/material/core';
import {MatDialog, MatDialogRef, MAT_DIALOG_DATA} from '@angular/material/dialog';
import { NgForm, FormControl, Validators } from '@angular/forms';

  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent {
  constructor(public dialog: MatDialog){}
  // button click function to open dailog with form
  openDialog() {
    const dialogRef =,
        width: '450px',


/** Error when invalid control is dirty, touched, or submitted. */
export class MyErrorStateMatcher implements ErrorStateMatcher {
  isErrorState(control: FormControl | null, form: FormGroupDirective | NgForm | null): boolean {
    //condition true
    const isSubmitted = form && form.submitted;
    return !!(control && control.invalid && (control.dirty || control.touched || isSubmitted));

//Dialog Component
  selector: 'dialog-overview-example-dialog',
  templateUrl: 'dialog-overview-example-dialog.html',
  styleUrls: ['app.component.css']
export class DialogOverviewExampleDialog {
  constructor(public dialogRef: MatDialogRef<DialogOverviewExampleDialog>) {}
  //Dialog close function 
  onNoClick(): void {

   /*Form validations*/
   unameFormControl = new FormControl('', [
    emailFormControl = new FormControl('', [
    pwdFormControl = new FormControl('', [

    matcher = new MyErrorStateMatcher();

5. 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:

<button mat-raised-button color="primary" (click)="openDialog()" >Login</button>

6. Now friends in last we need to create new file `dialog-overview-example-dialog.html` into our project/src/app/ folder and add below code inside it:

<h1 mat-dialog-title>User Details:</h1>
<form >
  <mat-form-field appearance="fill">
      <mat-label>User Name</mat-label>
      <input matInput [formControl]="unameFormControl" [errorStateMatcher]="matcher" required>
      <mat-error *ngIf="unameFormControl.hasError('required')">
          Username is <strong>required</strong>
    </mat-form-field><br />
    <mat-form-field class="example-full-width" appearance="fill">
      <input type="email" matInput [formControl]="emailFormControl" [errorStateMatcher]="matcher"
             placeholder="Ex." required>
      <mat-hint>Errors appear instantly!</mat-hint>
      <mat-error *ngIf="emailFormControl.hasError('email') && !emailFormControl.hasError('required')">
        Please enter a valid email address
      <mat-error *ngIf="emailFormControl.hasError('required')">
        Email is <strong>required</strong>
    </mat-form-field><br />
    <mat-form-field appearance="fill">
      <input matInput [formControl]="pwdFormControl" [errorStateMatcher]="matcher" required>
        <mat-error type="password" *ngIf="pwdFormControl.hasError('required')">
          Password is <strong>required</strong>
      <mat-error *ngIf="pwdFormControl.hasError('minlength') && !pwdFormControl.hasError('required')">
          Max lenght <strong>8 char</strong>
    </mat-form-field><br /><br />
    <div mat-dialog-actions>
      <button type="submit" mat-raised-button color="primary">Submit</button>
      <button mat-button class="mat-focus-indicator mat-raised-button mat-button-base mat-raised" (click)="onNoClick()">Close!!</button>
