React Native Picker select：Android 是否有可用的回调？

Question

I'm using react-native-picker-select in my React Native app, and the two main callbacks I'm using for iOS are onClose() and onDonePress() . However, these are iOS only. Is there some approach you can use with Android to trigger a function when the user has closed the picker or pressed Done ? I know you can use onValueChange() , but this doesn't get triggered when the user is done, just when they iterate through the options in the picker.

onClose is iOS only, I was able to get a similar behavior for Android using onBlur of touchableWrapperProps (please make sure to add fixAndroidTouchableBug).

const handleOnClose = () => {};

<RNPickerSelect
          onClose={handleOnClose} // iOS only
          fixAndroidTouchableBug
          touchableWrapperProps={{ onBlur: handleOnClose }} // Android only
        />
