I'm trying to use a USDA API for farmers markets in a Flutter project. Here's the API instructions. https://www.usdalocalfoodportal.com/fe/datasharing/
I'm basically following this guidance to build the Flutter app and get the USDA API.
https://docs.flutter.dev/cookbook/networking/fetch-data
Any advice? Just can't seem to get it working. The basic scaffold works but it throws the exception error on the app simulator screen.
