Angular 18 FormBuilder error Property not initialized

I am doing a Dummy in Angular 18, I am using Reactive Forms and I an trying to implement FormBuilder

I have this constructor in my .ts

constructor(private builder:FormBuilder){

}


Then I try to create the form with the validations.

registerform= this.builder.group({
username:this.builder.control('',Validators.required),
name:this.builder.control('',Validators.compose([Validators.minLength(5),Validators.required])),
email:this.builder.control('', Validators.compose([Validators.email,Validators.required])),

});


But I got an error... saying

Property 'builder' is used before initialization


The html has his header.

<form class="example-form" [formGroup]="registerform" (ngSubmit)="ProceedRegister()">


I saw others examples that do not throw any errors.

How can I initialized this property?

Thanks
