Does using indexes work for you?
<v-row class="d-block d-md-flex">
<v-col v-for="(planning, index) in module.plannings" :key="planning.id">
<v-textarea
outlined hide-details dense
:label="planning.name"
@input='(evt) => { updateItem(index, evt.target.value) }'
:value="planning.text"></v-textarea>
</v-col>
</v-row>
//
...
methods: {
updateItem(index, value) { this.module.plannings[index].text = value; }
}
