Package Exports

@hashiprobr/expo-use-locator
@hashiprobr/expo-use-locator/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@hashiprobr/expo-use-locator) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

expo-use-locator

A React Hook for simplifying basic usage of expo-location

This hook returns an object with two properties:

a boolean state reading, that indicates whether it is waiting for the delivery of the user's current location;
an asynchronous method read, that requests and returns the aforementioned location.

Before requesting, this method asks for permission to access the device, if necessary, and throws an error if it is not granted.
