au User asyncomplete_setup call asyncomplete#register_source(asyncomplete#sources#flow#get_source_options({
    \ 'name': 'flow',
    \ 'allowlist': ['javascript'],
    \ 'completor': function('asyncomplete#sources#flow#completor'),
    \ 'config': {
    \    " Resolves 'flow' in the closest node_modules/.bin directory (in case
    \    " flow is installed via 'npm install flow-bin' locally). Falls back to
    \    " 'flowbin_path' (see below) if can't find it.
    \    'prefer_local': 1,
    \    " Path to 'flow' executable.
    \    'flowbin_path': expand('~/bin/flow'),
    \    " Displays additional typeinfo exposed by flow, if any is provided. 
    \    " Defaults to 0.
    \    'show_typeinfo': 1
    \  },
    \ }))

Note: config is optional. flowbin_path defaults to flow i.e., flow binary should exist in the PATH if config is not specified.

Also make sure your javascript project is correctly initialized with .flowconfig.
