Flow fails: cannot determine object type for ____ShadowStyle_Internal because ____ShadowStyle_InternalOverrides is inexact.

Description

Tried making a clean expo project and adding Flow to it. I ran yarn flow init, changed the config a little (adding an ignore), and then ran yarn flow status and got this error after editing the App.js file a bit:

Error ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ App.js:15:20

Cannot create Text element because Flow cannot determine a type for object type [1].
____ShadowStyle_InternalOverrides [2] is inexact, so it may contain shadowRadius with a type that conflicts with
shadowRadius's definition in ____ShadowStyle_InternalCore [3]. Try making ____ShadowStyle_InternalOverrides [2] exact in
property style. [incompatible-type]

     App.js
      12│         backgroundColor: "blue",
      13│       }}
      14│     >
      15│       <Text style={{ color: "blue" }}>
      16│         Open up App.js to start working on your app!
      17│       </Text>
      18│       <StatusBar style="auto" />
