Storing API keys in a JSON file¶

Did you know?

Since Flutter 3.7, you can store all your API keys inside a JSON file and pass it to a new --dart-define-from-file flag from the command line.

(you’ll want to add that JSON file to .gitignore to avoid exposing your sensitive keys)

Then in your Dart code, simply use String.fromEnvironment to retrieve your keys and use them as needed. 👇
