@hashiprobr/expo-use-picker v1.0.5

expo-use-picker

A React Hook for simplifying basic usage of expo-document-picker

This hook returns an object with two properties:

• a boolean state loading, that indicates whether it is waiting for a file to load;

• an asynchronous method load, that asks the user to choose the aforementioned file and returns its URI.
