When submitting is done perfectly even if errors come out

Question

I have a form, with a minimum of characters and a maximum, the problem is that if the minimum is 2 characters and I put one I get the mat-error but when giving save it lets you save it with only one character.

 <mat-form-field>
        <input matInput #input1 maxlength="300" minlength="2"
                placeholder="Nombre"
               formControlName="name">
        <mat-hint align="end">{{input1.value?.length || 0}}/300</mat-hint>
        <mat-error>
           Minimo 2 caracteres máximo 300
        </mat-error>
</mat-form-field>

The save button:

 <button  class="mat-raised-button mat-primary"  (click)="save()">Save</button>

The save function:

    save() {
    this.dialogRef.close(this.form.value);
  }

Answer 1

use Form submit

<form [formGroup]="form" (ngSubmit)="save()" class="example-form">
<mat-form-field>
    <input matInput #input1 maxlength="300" minlength="2"
            placeholder="Nombre"
           formControlName="name">
    <mat-hint align="end">{{input1.value?.length || 0}}/300</mat-hint>
    <mat-error>
        Minimo 2 caracteres máximo 300
    </mat-error>
</mat-form-field>
<button type="submit"> save</button>

In component.ts

save(){
  if(this.form.valid){
  console.log('saved')
  }
  else{
     console.log('invalid form')
  }
}
