Angular Material 7 - SnackBar

The <MatSnackBar>, an Angular Directive, is used to show a notification bar to show on mobile devices as an alternative of dialogs/popups.

In this chapter, we will showcase the configuration required to show a snack bar using Angular Material.

Following is the content of the modified module descriptor app.module.ts.

import { BrowserModule } from  @angular/platform-browser ;
import { NgModule } from  @angular/core ;
import { AppComponent } from  ./app.component ;
import {BrowserAnimationsModule} from  @angular/platform-browser/animations ;
import {MatButtonModule,MatSnackBarModule} from  @angular/material 
import {FormsModule, ReactiveFormsModule} from  @angular/forms ;
@NgModule({
   declarations: [
      AppComponent
   ],
   imports: [
      BrowserModule,
      BrowserAnimationsModule,
      MatButtonModule,MatSnackBarModule,
      FormsModule,
      ReactiveFormsModule
   ],
   providers: [],
   bootstrap: [AppComponent]
})
export class AppModule { }

Following is the content of the modified HTML host file app.component.html.

<button mat-button (cpck)="openSnackBar( Party ,  act )">Show snack-bar</button>

Following is the content of the modified ts file app.component.ts.

import {Component, Injectable} from  @angular/core ;
import { MatSnackBar } from "@angular/material";
@Component({
   selector:  app-root ,
   templateUrl:  app.component.html ,
   styleUrls: [ app.component.css ]
})
export class AppComponent {
   constructor(pubpc snackBar: MatSnackBar) {}
   openSnackBar(message: string, action: string) {
      this.snackBar.open(message, action, {
         duration: 2000,
