How to implement functionality for using .env variables? Let’s see…

To use environment variables from .env files we will use flutter_dotenv package.

First, we’ll need to add flutter_dotenv package to our dependencies:

flutter_dotenv: ^2.1.0

Import flutter_dotenv package in main.dart file:

import 'package:flutter_dotenv/flutter_dotenv.dart';

Next, we will change our main method from…

void main() => runApp(MyApp());

to…

Future main() async {
await DotEnv().load('.env');
runApp(MyApp());
}

To extract .env variable, VAR_NAME=HELLO_WORLD, for example, we will need to use this syntax:

import 'package:flutter_dotenv/flutter_dotenv.dart';// some classprint(DotEnv().env['VAR_NAME'])
