installed "flow" in package.json and incorporated into github workflow

[J0nathanLai]

This static analysis type checker tool "Flow" was not installed in the first checkpoint and has just been added as a tool we want to integrate.

In order to install flow, run npm install --save-dev flow-bin This will install the package flow into your project. You can see the changes inside the package.json file on line 164 where you will see "flow-bin": "^0.250.0" Inside the package.json file, add "flow": "flow"'to line 18 after the coveralls script.

The above steps would allow you to use the flow package locally.

Then to run this tool, run the command npm run flow init the first time you run this tool. This will generate the file .flowconfig which has been added to the files changed.

Then, run the command npm run flow which will actually check your code against the tool. Look for the "No errors!" line in the output.

We can see that there aren't any errors or warnings that the Flow tool is flagging.

Lastly, to integrate the tool into the workflow on Github, copy the code or the changes you made from package.json into install/package.json. This is because the Github workflow uses the packages from install/package.json. Then, go to .github/workflows/test.yaml and add the installation line and the run flow line.
