We have public reset method that you can use to manually reset the plugin. Our docs API is missing this information and will be updated in the near future. Here is some code:

Template:

        <mdb-file-upload #fileUpload></mdb-file-upload>
        <button class="btn btn-danger" (click)="handleClick()">
          Reset file upload
        </button> 

Component class:

        import { Component, ViewChild } from '@angular/core';
        import { MdbFileUploadComponent } from 'mdb-angular-file-upload';

        @Component({
          selector: 'app-root',
          templateUrl: './app.component.html',
          styleUrls: ['./app.component.scss'],
        })
        export class AppComponent {
          @ViewChild('fileUpload') fileUpload!: MdbFileUploadComponent;

          handleClick(): void {
            this.fileUpload.reset();
          }
        }
