yarn bootstrap fails with invalid podfile error

[zakini]

I'm trying to get this repo set up locally so I can put together a PR, but I'm getting stuck when running yarn bootstrap

Steps to reproduce:

git clone [email protected]:react-native-menu/menu.git
cd menu
yarn bootstrap

Output from yarn bootstrap:

yarn run v1.22.18
$ yarn example && yarn && yarn pods
$ yarn --cwd example
