Why use Reactive Forms?

1. Ease and clean way of collecting data from your Forms.

No more onSave, onChanges, onEditionCompleted callbacks needed or TextEditionControllers to collect data from inputs and get syncronizations between model and widgets values. Goodby to verbose and boilerplate code.

Reactive Forms get a clean separation between views an model and maintains synchronization between your model and widgets in a transparent way with two-binding mechanism, you don't have to collect data, it does it for you. So you just define your model, declare your widgets and then layback and relax, data will flow smoothly.

2. Transparent Validations of inputs fields.

No more StatefulWidget defining a key for the Form widget, goodbye to Form.of(context) and goodbye to:

if (form.validate()) {
  form.save();
}

In Reactive Forms Validations occurs transparently, you don't have to write boilerplate code in each of your Forms to take care manually of this kind of tasks. Just declare your model and define the validators you need, Reactive Form will handles it for you. It will handle validity of controls and validity of the entire Form. It will shows error messages and will mantains validity syncronization. All of that without you need to write a single imperative line of code to handle it.

// just declare your Form and validators
final form = FormGroup({
  'email': FormControl(validators: [
    Validators.required,
    Validators.email,
  ]),
});

3. Enable/Disable buttons depending of Form validity.

4. Perfect integration with Provider plugin and other state management plugins.

5. Focus/Unfocus text fields ease and clean.
