title: How to get picker label and value and pass to a function
body: <p>I am trying to get my picker label and value in a function because they all carry different values and I will need both the label and value content to work with. Thank you for your help</p>
  
  <pre><code>  onValueChangeInvoiceType(value: string){
      this.setState({
        invoiceType: value,
      });
    }
  
  
  
    &lt;Picker 
      mode="dropdown" 
      style={{flex: 1}} 
      textStyle={{color: '#696969' }} 
      selectedValue={this.state.invoiceType} 
      onValueChange={this.onValueChangeInvoiceType.bind(this)}&gt;
        &lt;Picker.Item label="Select Option" value="" /&gt;
        &lt;Picker.Item label="BOP" value="1" /&gt;
        &lt;Picker.Item label="UNASSESSED BUS PROP" value="2" /&gt;
        &lt;Picker.Item label="UNASSESSED RES PROP" value="3" /&gt;
        &lt;Picker.Item label="FEES" value="4" /&gt;
        &lt;Picker.Item label="FINES" value="5" /&gt;
        &lt;Picker.Item label="BUILDING PLAN PERMIT" value="6" /&gt;
        &lt;Picker.Item label="PERMIT CHARGES" value="7" /&gt;
        &lt;Picker.Item label="RENT" value="8" /&gt;
        &lt;Picker.Item label="PERMIT" value="9" /&gt;
        &lt;Picker.Item label="BUSINESS PROPERTY RATE" value="12" /&gt;
        &lt;Picker.Item label="RESIDENCE PROPERTY RATE" value="13" /&gt;
    &lt;/Picker&gt;
  &lt;/Item&gt;
  </code></pre>
  
  <p>I want to know how I can pass the label content also to the onValueChangeInvoiceType function.</p>
