Install:
yarn global add flow-typed /*get type defination*/ yarn add flow-bin -D
For example you have installed lodash libaray, and you want the defination file also, you can do:
flow-typed install
It will help to install the files automaticlly.
If you running flow with Node.js, the syatax:
const result: number = _.min([,1,2]);
cannot be understand by node.js.
You can do:
const result/* :number*/ = _.min([1,2])
or you can use Babel.
