In my application I have a snackbar .

Now I want to set an Icon inside the snackbar but I trie

Answer 1

This how I did it

1. Create a component
2. Create a Service for the snackBar
3. add the component to a module. import it in declarations and entryComponents
4. Use the service

example

my-snackbar.component.ts

 import { Component, OnInit, Inject } from '@angular/core';
 import { MAT_SNACK_BAR_DATA } from '@angular/material/snack-bar';

    @Component({
      selector: 'my-snackbar',
      templateUrl: './snackbar.component.html',
      styleUrls: ['./snackbar.component.scss']
    })
    export class MySnackbarComponent implements OnInit {
      constructor(@Inject(MAT_SNACK_BAR_DATA) public data: any) {
        console.log(data); 
      }

      ngOnInit() {}

      get getIcon() {
        switch (this.data.snackType) {
          case 'Success':
            return 'done';
          case 'Error':
            return 'error';
          case 'Warn':
            return 'warning';
          case 'Info':
            return 'info';
        }
      }
    }

.........

my-snackbar.component.html

  

    {{getIcon}}
  
  

    {{data.message}}
  

.........

my-snack-bar.service.ts

import { Injectable } from '@angular/core';
import { MatSnackBar } from '@angular/material/snack-bar';
import { MySnackbarComponent } from '../components/snackbar/my-snackbar.component';

@Injectable({
  providedIn: 'root'
})
export class MySnackBarService {
  constructor(private snackBar: MatSnackBar) {}
  public openSnackBar(message: string, action: string, snackType?: snackType) {
    const _snackType: snackType =
      snackType !== undefined ? snackType : 'Success';

    this.snackBar.openFromComponent(SnackbarComponent, {
      duration: 2000,
      horizontalPosition: 'end',
      verticalPosition: 'top',
      data: { message: message, snackType: _snackType }
    });
  }
}

........

app.module.ts

@NgModule({
  declarations: [
    SnackbarComponent
  ],
  imports: [
...
  ],
  providers: [],
  bootstrap: [AppComponent],
  entryComponents: [
    SnackbarComponent
  ]
})
export class AppModule {}

.......

other.component.ts

import { Component, OnInit } from '@angular/core';
import { MySnackBarService } from '../../services/my-snack-bar.service';

@Component({
...
})
export class SomeComponent implements OnInit {

  constructor(
    private snack: MySnackService
  ) {}

  ngOnInit() {
  }


  openSnack() {
    this.snack.openSnackBar('Testing snack', '', 'Success');
  }
}
