Flow has recently landed support for
declare
fields, similar to TypeScript. (facebook/flow@11b7adb)This PR implements parser support, and adds an
allowDeclareFields
option to the transform plugin to mirror the one of@babel/plugin-transform-typescript
. In Babel 8 it will be enabled by default.Even if it's not released yet in Flow, I'm adding this to the v7.9.0 milestone since Flow is released about once a week.
