I've start to use got in project that use flow. And to help me to catch misuse of the library I've written the got flow definition. Feel free to add it to the repository if you feel it useful for the project 😉

@Spy-Seth it is better to add them to flow-typed. See sindresorhus/ama#439

I actually knew this one but man you are fast @floatdrop 😉 .

Also cool to see a flowtype definition @Spy-Seth. Been meaning to try it out more myself. Let me know if you don't feel like PR-ing it into flow-typed because I'll look into it then! This should be shared 😄 .
