will not render for React Native 37

[skyride99]

It just blows up in render.

Which version of the picker? 3 or 4? 3 isn't showing up for me.

[skyride99]

Android, version 4+ of the picker.
Also version 3 does not show up, there is nothing inside the picker.

So there is a breaking change to RN36 that has to do with changing flex to flexGrow, you can get it to look like this other issue by changing this on the picker container.
I looked at v4+ and it's working fine. It actually feels a lot better but it's far less customizable. I think it's definitely worth using something that feels better natively. I would try it again and make sure you are using it correctly.

I went back to RN 0.32 and 4.10 of the picker

I have something like this:

<Picker
ref={'refCategory'}
style={{height: 300, backgroundColor: '#fff'}}
pickerHeight={300}
showDuration={300}
pickerData={['Resort', 'Dive Shop', 'Vehicle' ]}
pickerCancelBtnText={''}
pickerBtnStyle={{color: '#439FDF'}}
selectedValue={this.state.selectedOption}
onValueChange={(value) => this.changeCategory(value)}
/>
And that will not render.... is there something different in the API for 4?

Use like this

 import Picker from 'react-native-picker';

    let data = [];
    for(var i=0;i<100;i++){
        data.push(i);
    }

    Picker.init({
        pickerData: data,
        selectedValue: [59],
        onPickerConfirm: data => {
            console.log(data);
        },
        onPickerCancel: data => {
            console.log(data);
        },
        onPickerSelect: data => {
            console.log(data);
        }
    });
    Picker.show();

I'm pretty sure you're not on 4.10, it's a completely different implementation just like mentioned above

[skyride99]

ok i got 4.10 working. But how do you have multiple pickers?

import Picker1 from 'react-native-picker';
import Picker2 from 'react-native-picker';

Picker1.init({});
Picker2.init({});

Picker1.show();
Picker2.show();

Is that right?
