refactor: converted all internal state/memoized variables to reanimated shared values.

[gorhom]

#427

Motivation

I have refactored the library to use shared values to store and update layout values.

Notice

Calculating snap points position had change in this branch, now the library will count the handle height when positioning the sheet. This is a breaking change and will require developers to carefully monitor the change.

This is how you can visualise it:

Installation

yarn add ssh://git@github.com:gorhom/react-native-bottom-sheet#refactor/convert-variables-to-shared-values
