UI Kitten Select Exception

Question

I basically copy/pasted the example from the documentation

         <Select
          selectedIndex={this.currLangIndex}
          onSelect={(index) => {
            this.currLangIndex = index;
          }}>
          <SelectItem title="Option1" />
          <SelectItem title="Option2" />
        </Select>

and I get the following error:

 TypeError: undefined is not an object (evaluating 'props.getItem')
 This error is located at:
    in FlatList (created by List)
    in List (created by Context.Consumer)
    in Wrapper (created by List)

I'm new to React Native and UI Kitten so any help is appreciated.

Answer 1

const [selectedIndex, setSelectedIndex] = useState(new IndexPath(0));


<Layout style={styles.container} level='1'>
  <Select
    selectedIndex={selectedIndex}
    onSelect={index => setSelectedIndex(index)}>
    <SelectItem title='Option 1'/>
    <SelectItem title='Option 2'/>
    <SelectItem title='Option 3'/>
  </Select>
</Layout>

I got same problem , but it worked when wrapped it with Layout Comp. from UI Kitten, but now it is not showing any option when trying to select
