Why is my flow not type checking?

Why is flow not type checking function args for me? Or I dont think its type checking anything at all, even though it is in the app.

.flowconfig

[ignore]
.*/build
.*/docs
.*/node_modules
.*/public

[include]

[options]
module.system.node.resolve_dirname=node_modules
module.system.node.resolve_dirname=src

How to setup flow is out of scope of the project, but you can try run flow ls to see which files flow can see and flow check possibly with --verbose flag for more options see flow --help and flow check --help

No. I did and it works now.
