Vuetify stepper alert message when blanks not filled

I have gotten some help in making this Vuetify stepper code but I have one last question. I have understood that there are rules you can set, so that those blanks must be filled out. For example in my code, when you haven't filled the blanks in step 3 and want to continue, it does not let you. But when you have not filled the blanks in step 2 it just lets you finish.

Is there a way to let the user know under which step the requirements have not been met by for example displaying alert message which should be something like this :rules="[() => false]" and when user has filled the blanks to switch the icon back to normal?

Here is the code:

For more complicated validation, I prefer to use library like Vee Validate

Added to your script

Vue.use(VeeValidate);

Basically, each step will become:

<v-stepper-step :complete="step > 1" 
                step="1" editable 
                :rules="[() => !errors.has('name') && !errors.has('email')]">
    Person
</v-stepper-step>
<v-stepper-content step="1">
    <v-text-field name="name" 
                  label="Name" 
                  v-model="registration.name" 
                  v-validate="'required'" 
                  :error-messages="errors.collect('name')">
    </v-text-field>
    <v-text-field name="email" 
                  label="Email" 
                  v-model="registration.email" 
                  v-validate="'required|email'" 
                  :error-messages="errors.collect('email')">
    </v-text-field>
    <v-btn color="primary" @click.native="step = 2">Continue</v-btn>
</v-stepper-content>

Note that how v-validate and errors.has are used. You can checkout demo at https://codepen.io/ittus/pen/ZoRyKv
