@Component({
    selector: 'app-form',

export class MyFormComponent
{

    public form: FormGroup;

    constructor(
        private $fb: FormBuilder,
    ) {
        this.form = this.createForm();
    }

    public onSubmit(values: any): void
    {
        console.log(values.file);
    }

    public fileChanged(files: Array<Blob>): void
    {
        console.log('CHANGED');
        console.log(files);
