Thanks for the PR! Just a few observations

1. You don't need custom putIntoMap function. Arguments class provides a super helpful fromBundle method which you can use to convert Bundle to WritableMap.
2. It would be better to rename extras key with a more meaningful word. Since the android doc says it provides Provider specific information, so providerInfo should do the job I think.
3. Please add it to the typings.
