use env flutter
You can do that by inserting in the .env file:
HOST=localhost
PORT=3000
Add the .env file in the assets section of the pubspec.yaml:
assets:
- .env
Then, you can change the main function in the main.dart to load the .env file:
Future main() async {
await DotEnv().load('.env');
runApp(MyApp());
}
After that, you can get the HOST and PORT anywhere with:
DotEnv().env['PORT'];
DotEnv().env['HOST'];
All these instructions are in the README of the library: https://pub.dev/packages/flutter_dotenv#-readme-tab-
