Question

         <Picker
          label={strings('Uploaddocs.Identity_Type')}
          width={metrics.width - metrics.getW(40)}
          value={this.state.idType}
          data = {identityType}
          valueExtractor={(item) => item.value}
          labelExtractor={(item) => item.value}
          onChange={(value, index, item) => {
            this.setState({ idType: value})
          }}
        />

above label is = 'identity type' data is = [{value:passport, value:driving licence , value:id card}]
