It is always a fear that one day you might end up leaking your API key in a public git repository. In flutter is there are many ways of hiding the API key some are not working and some don't work properly in this article I will be showing you one way to work with API keys in flutter.
Let's see how we can do it
We will be using this package
If you are using it in a project with null safety
dependencies:
flutter_dotenv: ^4.0.0-nullsafety.0
If you are using it in a project without null safety
dependencies:
flutter_dotenv: ^3.1.0
then create a file in the root directory called .env
For those of you who don't know what a
.envfile is it is basically a file in which we store secret variables.
In the .env file you can add your secret API keys in this format
SUPER_SECRET_API_KEY=This is a super secret API key
THIS_CAN_BE_CALLED_ANYTHING=This here can be anything like ut4ihyeFn49
Important: Never commit these .env files in your version control.
If you are using git version control system add the.envfile to.gitignore
After making this .env file add it as an asset in the pubspec.yaml
assets:
- .env
Then run
flutter pub get
In your main.dart file load the .env file
import 'package:flutter_dotenv/flutter_dotenv.dart' as DotEnv;
Future main() async {
await DotEnv.load(fileName: ".env");
//...runapp
}
Now in your code you can load the variables from the .env file anywhere like this.
import 'package:flutter_dotenv/flutter_dotenv.dart';
env['SUPER_SECRET_API_KEY'];
That's it, thanks for reading hope this short article helps!
