get-flow-type.vim

" Uses Dispatch to print the flow type of the variable under the cursor.
"
" Example:
"
" ```javascript
"
" type Person = {age: number, name: string, sex: 'male' | 'female'}
" const person: Person = {age: 35, name: 'Bob', sex: 'male'};
" const {a|ge, sex} = person;
"         ^
"         cursor
"
" // Would print `number`.
"
" const {age, s|ex} = person;
"              ^
"              cursor
"
" // Would print `'male' | 'female'`.
" ```
function! GetFlowType()
    let cursorcolumn = col('.')
    let cursorline = line('.')
    let localflow = "~/khan/webapp/node_modules/.bin/flow"

    execute "Dispatch " . localflow . " type-at-pos --quiet " . expand('%:p') . " " . cursorline. " " .cursorcolumn
endfunction

This line could use some love. We should probably check for the flow binary in a safer way but 🤷‍♂️
