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 (click)="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(public snackBar: MatSnackBar) {}
   openSnackBar(message: string, action: string) {
      this.snackBar.open(message, action, {
         duration: 2000,
      });
   } 
}
