[Question] Select picker

[DCKT]

Hello,

I didn't find anything for select a Picker.Item with precision, do you know how to do it ?

Thanks !

For pickers to work with Detox, we need to add API for scrolling from a point to a point, where then you would be able to scroll to the item you desire. We plan to add this soon, and it is tracked in #154.

I'm not sure that scrolling is the way to approach pickers. Wouldn't it be better to be able to set a wheel to a particular value?

@colinramsay you're right, and EarlGrey actually have lots of actions that we can support pretty easily, we just need to expose them with our API.

Actually, this can be a great PR.
This is where we invoke EarlGrey methods, and more specifically, configure actions:

+ (id<GREYAction>)actionForSetPickerColumn:(NSInteger)column toValue:(NSString *)value;

Interesting. However, this is a very naive approach, as picker views can have custom views. Still interesting. I'll open a new issue for discussing additional actions we may want to support.

This is being worked on as we speak in #605
