Flow introduced a new syntax to annotated the context type of a
function, this tries to update the rest and add 1 example usage.
- 2b1fb91a55 already added the changes
required for eslint.
- Jest transform is updated to use the recommended `hermes-parser` which
can parse current and Flow syntax and will be updated in the future.
- Rollup uses a new plugin to strip the flow types. This isn't ideal as
the npm module is deprecated in favor of using `hermes-parser`, but I
couldn't figure out how to integrate that with Rollup.
