Enables Babel to parse Flow syntax. This plugin allows Babel to understand and process Flow type annotations in your JavaScript code, but it doesn't remove or transform the types. It prepares the code for further processing by tools that specifically handle Flow type checking or conversion. A crucial prerequisite for using other Babel plugins that work with Flow types, like removing or converting them to TypeScript. Requires Babel version 7.0.0 or later.
