I'm using react-native picker in dialog mode. Now I want to call a function whenever the dialog opens. How can I achieve that because there is no onPress prop? Any help will be appreciated. Please don't recommend any other packages because I want to use the default one.
You can achieve it without using Picker, use TouchableOpacity to call a function, and in the same function just open a Modal for showing the list of items of Picker and close the Modal when selecting any item from the list.

I am using modal for React Native UI kitten.
But the problem is I did't find anything like onRequestClose prop like the React Native provides for the modal. Nothing mentioned on their API also.
So is there anything like I can close the modal on back button press?

If so, then you need to use Modal component.
Here's the link to the docs of modal component -

My react native version is 0.55.4 , when modal showing keyboard dismiss , how can show modal without dismissing keyboard.
You need a little hack!
For example you can auto focus on a input in your modal (More info)
Or use a custom modal that not related with native keyboard (You can write this yourself or use some package like this)

You can use the renderKnob prop as mentioned in the docs to render your own icon
