React.createElement: type is invalid about picker

[Aidurber]

A PR has been created for this fix, awaiting for review and approval.

If you use something like patch-package, this fix is just to return UnimplementedView not <UnimplementedView /> in both PickerAndroid.ios.js and PickerIOS.android.js

This seems to be back, using "react-native": "~0.61.5", and "@react-native-community/picker": "^1.3.0",

Here's the code:

const [tipValue, setTipValue] = useState(0.2);

...

<Picker
  selectedValue={tipValue}
  onValueChange={(itemValue, itemIndex) => setTipValue(itemValue)}
  style={{ width: "100%", height: 50 }}
>
  <Picker.item label="Fair" value={0.1} />
  <Picker.item label="Reasonable" value={0.2} />
  <Picker.item label="Generous" value={0.35} />
  <Picker.item label="Outrageous" value={0.5} />
  <Picker.item label="Are you nuts?!" value={1} />
</Picker>

Here's the error I'm getting:

ExceptionsManager.js:126 Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

I have this warning as well.
Using:
"@react-native-community/picker": "^1.6.1",
"react-native": "^0.62.0",
Code:
`
import {Picker} from '@react-native-community/picker';
...
<Picker
style={this.styles.picker}
selectedValue={data.LadderModel}
onValueChange={(itemValue) => {
this.changeLadderModel(itemValue, data_id);
}}

<Picker.item label="Model 3" value="3" />
<Picker.item label="Model 4" value="4" />
<Picker.item label="Model 5" value="5" />
<Picker.item label="Other" value="other" />

`
