Step 3: Import Module

In third step, we need to import some dependency like MatCheckboxModule and MatButtonModule. so let’s add.

src/app/app.module.ts

import { NgModule } from '@angular/core';

import { BrowserModule } from '@angular/platform-browser';

import { AppComponent } from './app.component';

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

import { FormsModule, ReactiveFormsModule } from '@angular/forms';

import { MatButtonModule } from '@angular/material/button';

import { MatCheckboxModule } from '@angular/material/checkbox';

@NgModule({

declarations: [

AppComponent

],

imports: [

BrowserModule,

BrowserAnimationsModule,

FormsModule,

ReactiveFormsModule,

MatButtonModule,

MatCheckboxModule

],

providers: [],

bootstrap: [AppComponent]

})

export class AppModule { }

Step 4: Updated ts file

Now in ts file, add bellow code:

src/app/app.component.html

import { Component } from '@angular/core';

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

@Component({

selector: 'app-root',

templateUrl: './app.component.html',

styleUrls: ['./app.component.css']

})

export class AppComponent {

title = 'app-material2';

form: FormGroup = new FormGroup({});

/*------------------------------------------

--------------------------------------------

Defined constructor

--------------------------------------------

--------------------------------------------*/

constructor(private fb: FormBuilder) {

this.form = fb.group({

i_agree: ['', [Validators.required]],

i_agree_terms: ['', [Validators.required]],

})

}

/*------------------------------------------

--------------------------------------------

Define f()

--------------------------------------------

--------------------------------------------*/

get f(){

return this.form.controls;

}

/*------------------------------------------

--------------------------------------------

Defined submit()

--------------------------------------------

--------------------------------------------*/

submit(){

console.log(this.form.value);

}

/*------------------------------------------

--------------------------------------------

Defined change event

--------------------------------------------

--------------------------------------------*/

onChangeEvent(event: any){

console.log(event.checked);

}

}

Step 5: Update html file

Now in view file, we will write code of input element with checkbox.

You can change color with two ways:

First, you can change color using color attribute.

Second, you can change color using css.

Let’s see both ways here:

src/app/app.component.html

<h1>Angular Material Checkbox Change Event Example - ItSolutionStuff.com</h1>

<form [formGroup]="form" (ngSubmit)="submit()">

<mat-checkbox

color="primary"

formControlName="i_agree"

(change)="onChangeEvent($event)">

I Agree for condition...</mat-checkbox>

<br/>

<mat-checkbox

formControlName="i_agree_terms"

(change)="onChangeEvent($event)">

I Agree with terms and conditions...</mat-checkbox>

<br/>

<button mat-raised-button color="accent">Submit</button>

</form>

Step 6: Update css file

you can change color using css file as well.

src/app/app.component.css

mat-checkbox ::ng-deep .mat-checkbox-inner-container {width: 30px;height: 30px;}

Run Angular App:

All the required steps have been done, now you have to type the given below command and hit enter to run the Angular app:

ng serve

Now, Go to your web browser, type the given URL and view the app output:

http://localhost:4200

now you can check it.

Output:
