For Expo this will work.The React native picker suggested in their expo documentation was not working for me over version of 36 react native expo sdk.

import { Picker } from 'react-native' 
// state
 const [picked, setPicked] = useState(1.15);

 <Picker
        selectedValue={picked}
        style={{ height: 50, width: 100 }}
        onValueChange={(itemValue, itemIndex) =>
          setPicked(itemValue)
        }>

        <Picker.Item label="Canda 5%" value={1.05} />
        <Picker.Item label="Japan 8%" value={1.08} />
        <Picker.Item label="USA 10%" value={1.10} />
        <Picker.Item label="Egypt 14%" value={1.14} />
        <Picker.Item label="Saudi Arabia 15%" value={1.15} />
        <Picker.Item label="China 16%" value={1.16} />
        <Picker.Item label="Algeria 17%" value={1.17} />
        <Picker.Item label="18%" value={1.18} />
        <Picker.Item label="German 19%" value={1.19} />
        <Picker.Item label="German 19%" value={1.20} />
</Picker>
