Motivation

Explain the motivation for making this change. What existing problem does the pull request solve?

I would like to have some kind of hook useNetworkReachable(). Exporting the context allows me to do this. I was wondering if there was any reason why it's not already exported?

Test plan

Demonstrate the code is solid and make sure you add tests to cover the new functionality.

The code must pass tests. It's an export...

Code formatting

Look around. Match the style of the rest of the codebase. Run yarn format before committing.

Hey @sbelzile-nexapp,

Thanks for your contribution. I thought it was easier to provide the hook out of the box, as well as proper docs. I'll ship a new version in the next minutes.

@all-contributors please add @sbelzile-nexapp for ideas
