you dont have to provide a value to auto-grow(presence of auto-grow prop indicates true and absence false). Just having auto-grow is enough. As in
<v-textarea auto-grow ></v-textarea>

Either use
<v-textarea :auto-grow="true"></v-textarea>
or
<v-textarea auto-grow></v-textarea>
The first one notifies that you are using a prop with initializing a value.
The second one just notifies you are using a default prop.
