Issue Description

Expected behaviour

Actual behaviour

When Item Picker is shown, the 'VirtualizedLists should never be nested inside plain ScrollViews with the same orientation - use another VirtualizedList-backed container instead.' warning shown.

Steps to reproduce

<Item picker>
                        <Picker
                            mode="dropdown"
                            iosIcon={<Icon name="arrow-down" />}

                            onValueChange={this.onValueChange2.bind(this)}
                        >

Is the bug present in both iOS and Android or in any one of them?

The bugs occur in iOS and Android. I have tested in iOS 14.4 and Android 11.0

Any other additional info which would help us debug the issue quicker.

Same here
I will provide you more details from Element inspector
So basically thats because Picker component renders FlatList inside VirtualizedList (screenshot below)

@Ajamuar I am also still having this problem in NativeBase v2 with the sample code. I realize you all are focused on v3 right now, but I hope you will continue to support v2 for a while until we get a chance to rewrite our app.

 <Container>
      <Header />
      <Content>
        <Form>
          <Item>
            <Input value="test" onChangeText={() => true} />
          </Item>
          <Item picker>
            <Picker
              mode="dropdown"
              iosIcon={<Icon name="arrow-down" />}
              style={{ width: undefined }}
              placeholder="Select your SIM"
              placeholderStyle={{ color: '#bfc6ea' }}
              placeholderIconColor="#007aff"
              selectedValue={selected2}
              onValueChange={() => true}
            >
              <Picker.Item label="Wallet" value="key0" />
              <Picker.Item label="ATM Card" value="key1" />
              <Picker.Item label="Debit Card" value="key2" />
              <Picker.Item label="Credit Card" value="key3" />
              <Picker.Item label="Net Banking" value="key4" />
            </Picker>
          </Item>
        </Form>
      </Content>
    </Container>

I hope the team at native base continue support for nativebase v2 and fix this issue. There are still many apps out there that uses v2

It isn't stale, its still an issue.

[jmgarciasanti]

Yes, still an issue. It's thrown as error on iOS devices after migrating app to Expo SDK 48. The error is shown in every screen I have with a Form including a "Select" Native Base component. The error is not thrown on Android.
